Building
--------
1. To compile:
> tar zxvf nxcomp-X.Y.Z-N.tar.gz
> cd nxcomp
> ./configure
> make
You'll have to run gmake under Solaris.
2. The 'make install' target is not currently supported
in the Makefile, but it should be simple to fix.
You need at least nxproxy and nxagent packages to enjoy this code. Check the
NoMachine website at http://www.nomachine.com to get the latest release.

nxcompext-3.0.0-15
- Separated the functionalities made available by NXQueryDisplay()
in three distinct functions:
NXDisplayReadable() Query the number of bytes readable from
the display connection.
NXDisplayFlushable() Query the number of the outstanding bytes
to flush to the display connection.
NXDisplayCongestion() Return a value between 0 and 9 indicating
the congestion level of the NX transport.
- Renamed NXQueryDisplayError() to NXDisplayError().
nxcompext-3.0.0-14
- Removed support for Rdp, Tight and Hextile packed images encod-
ing since they have been made obsolete by the new NX server.
- Changed the copyright attribution from Medialogic to NoMachine.
nxcompext-3.0.0-13
- Allocate 1024 additional bytes for the Jpeg compression, instead
of 512, to avoid failures on very tiny images.
- Removed support for the special *PNG_JPEG* pack method.
nxcompext-3.0.0-12
- Implemented the NXEncodeBitmap() method. This is a very simple
encoder removing the 4th byte in 32 bits-per-plane images. For
the other pixmap depths it simply returns a pointer to the orig-
inal image data, saving the copy. This encoding is intended to
better leverage the stream compression on low bandwidth links.
- Removed the quality parameter from the RGB/RLE encoding function.
nxcompext-3.0.0-11
- Removed the additional parameter in the call to NXTransFlush().
nxcompext-3.0.0-10

to NXproto.h to force fields to be CARD32.
- Fixed a typo in NXSetDisplayBuffer() that could cause a double
free.
- Fixed a compilation error with old GCC versions.
- Removed the warning issued on AMD64 when compiling with the logs
enabled.
nxcompext-3.0.0-9
- Added the NXDisplayCongestion query type to NXQueryDisplay(). It
returns a value between 0 and 9, with 9 meaning that the link is
congested and no further data can be sent.
- Added the NXSetDisplayBuffer() function. It allows the caller to
set the display output buffer size at runtime.
- Removed the congestion and synchronization callbacks.
nxcompext-3.0.0-8
- Removed the warnings issued when purging the collected data at
display reset.
nxcompext-3.0.0-7
- Added the NXSetDisplayWriteHandler() interface. The function
registers a callback that will be invoked every time more data
is written to the display socket.
nxcompext-3.0.0-6
- Made NXQueryDisplay() take into account the bytes in the display
buffer when queried for the bytes flushable.
nxcompext-3.0.0-5
- Added file COPYING.

- Imported changes up to nxcompext-2.1.0-4.
- Fixed TR12D01564. Changed configure script to build library with
-fPIC option.
- Added 256 byte to the size of Jpeg destination buffer.
nxcompext-3.0.0-2
- Updated the file VERSION.
nxcompext-3.0.0-1
- Opened the 3.0.0 branch based on nxcompext-2.0.0-33.
nxcompext-2.0.0-33
- Placed the inclusion of jpeglib.h after the X includes to fix a
possible compilation error.
nxcompext-2.0.0-32
- Avoid to copy the data to the scratch buffer and yield the task
of padding the output to _XSend() in the NXPutPackedImage(), NX-
SetUnpackAlpha() and NXSetUnpackColormap() requests.
- Added support for the RLE pack method.
nxcompext-2.0.0-31
- The X_NXSetUnpackColormap and X_NXSetUnpackAlpha now carry their
data in compressed form. The alpha data is compressed using the
ZLIB RLE encoding, while the colormap data is compressed using
the default ZLIB deflate.
- Created new message structures to handle the compatibility with
the old proxy versions. When connected to an old proxy version
the agent should use the NXSetUnpackColormapCompat() and NXSet-
UnpackAlpha() interfaces.
nxcompext-2.0.0-30
- Removed the unfriendly warning printed if a client tried to reset
the library multiple times.
nxcompext-2.0.0-29
- Made possible to compile even if makedepend is not found.
nxcompext-2.0.0-28
- Added the NXSetDisplaySynchronizationHandler() interface. The NX
transport will use the callback to report when the agent can use
the available bandwidth to synchronize the X objects that are
corrupted or incomplete.
- Bytes from 14 to 24 in the NXGetControlParameters() reply report,
respectively, the frame timeout, the ping timeout, the preferred
image split mode and the split size threshold.
nxcompext-2.0.0-27
- Changed the image cleanup functions and the Png and Jpeg encoders
to be independent from the host endianess.
- Enabled again the image cleanup on big endian machines.
nxcompext-2.0.0-26
- Added the NXAbortSplit() request.
- Added information about the size of the shared memory segment used
by the remote proxy in the NXGetShmemParameters() reply.
nxcompext-2.0.0-25
- Renamed the NXGetSplitResource() and NXGetUnpackResource() utili-
ties to NXAllocSplit() and NXAllocUnpack(). They can be called
with a NXAnyResource parameter to get the first available id or
requre a specific resource. From this version the resource must
be explicitly reserved. NXFreeUnpack() and NXFreeSplit() check
if the resource was allocated and don't do anything if it is not
the case. NXAllocSplit() and NXAllocUnpack() return NXNoResource
if the resource can't be reserved.
nxcompext-2.0.0-24
- NXFlushDisplay() now verifies whether the XlibDisplayWriting flag
is set before flushing the display buffer. in this case, it only
flushes the NX link.
nxcompext-2.0.0-23
- Implemented a move-to-front strategy for the image cache, to mi-
nimize the number of lookups.
- Fixed the problems imtroduced by the new cache implementation by
modifying the memory allocation routines in Jpeg.c and Pgn.c.
- Temporarily fixed the cleanup problems on big-endian machines by
skipping the operation.
- Added a NXSetDisplayStatisticsHandler() to let the agent include
arbitrary data in the transport statistics. The parameter is a
pointer to a pointer to a null terminated string. The pointer is
set at the time the handler is registered. The pointed string can
be filled by the agent with its statistics data.
nxcompext-2.0.0-22
- The NXCacheFindImage() returns a pointer to the checksum, if the
image is found.
- The image cache uses the data passed to NXCacheAddImage() instead
of making a copy.
- The Z stream used by the RGB encoder is allocated at initializat-
ion and freed at reset.
nxcompext-2.0.0-21
- Removed the reliance on the local byte order in the image cleanup
functions.
nxcompext-2.0.0-20
- Added the NXFinishSplit() request. It forces the proxy to comple-
tely transfer all the split messages for the given resource, and
then notify the agent.
nxcompext-2.0.0-19
- Enabled again the cleanup of images.
- Updated to comply with the new NXTransFlush() interface.
nxcompext-2.0.0-18
- Moved all the declarations in Rgb.c at the beginning of the block
to avoid the possible compilation errors with old compilers.
nxcompext-2.0.0-17
- Added a new RGB image encoder. For now the encoder uses a static
Z stream to compress the image data in the destination buffer and
allows the agent to use the simplest encoding by still separating
the alpha channel from the image data. The new encoder can be the
the base for implementing color reduction by dithering or a color-
mapped translation of the image similar to PNG, but without the
PNG overhead and with the colormap being sent to the client using
the NXSetUnpackColormap() opcode.
- Created a new NXCleanImage() function that takes a XImage pointer
and uses either the CleanXYImage() or the CleanZImage() routines
to cleanup the padding bits.
nxcompext-2.0.0-16
- Added a parameter to NXFlushDisplay() to specify what needs to be
flushed. The parameter can be one the following values, defined
in NXvars.h:
NXFlushBuffer Only the Xlib buffer is to be flushed.
NXFlushLink Flush both the Xlib buffer and any pending
data encoded by the NX transport.
NXFlushIdle Inform the NX transport that the agent is
idle. This will let the NX transport encode
more low-priority data, and then flush the
link.
- Ensured that the padding bytes are cleaned when creating a new
PNG image. It seems that some images are still missed. This is
to be investigated.
nxcompext-2.0.0-15
- Ensured that the packed image cache is recreated only on a size
change.
nxcompext-2.0.0-14
- Updated to get the karma delay field from the X_NXGetControlPara-
meters reply.
nxcompext-2.0.0-13
- Added the NXSetDisplayPolicy() and NXSetDisplayFlushHandler() in-
terfaces. The second function registers a callback that will be
invoked by the NX transport when the number of bytes encoded by
the proxy exceeds the threshold set for the scheduled write.
- Added the NXFlushDisplay() and NXQueryDisplay() interfaces. They
are used to hide the corresponding NX transport functions to the
application. NXQueryDisplay() can be called with the NXDisplay-
Flushable or NXDisplayReadable parameters, to get, repectively,
the number of bytes that are queued to the NX transport and the
number of bytes that is possible to read.
- Included the remote proxy version in the NXGetControlParameter()
reply.
nxcompext-2.0.0-12
- Added the NXGetSplitResource() and NXGetUnpackResource utilities.
These can be used by the client to find out the first unused id
available for a split or unpack operation.
- Added the NXFreeSplit() request function. It makes the resource
available for the next operation and tells the proxy to destroy
all the storage associated to the split.
- Renamed the NXNumberOfConnections constant to NXNumberOfResources.
nxcompext-2.0.0-11
- Changed NXForceDisplayError() to also shut down the NX transport
by calling NXTransClose().
- Updated to comply with the new NX function prototypes introduced
in nxcomp-2.0.0-31.
nxcompext-2.0.0-10
- NXQueryDisplayError() now checks the predicate function only if
the I/O error was not encountered already.
nxcompext-2.0.0-9
- Added the NXSetDisplayErrorPredicate(), NXSetDisplayBlockHand-
ler(), NXSetDisplayCongestionHandler(), NXSetLostSequenceHand-
ler() interfaces to let the user set the values used internal-
ly. All functions return the previous handler. See ChangeLog
in nx-X11-2.0.0-16 and nx-X11-2.0.0-17.
- Moved all the internal variables shared between Xlib, nxcompext
and the X server in nxcomp. Declarations and function prototypes
moved to NXvars.h.
- Some name changes. In particular the NXContinueOnDisplayError()
function iss renamed NXHandleDisplayError() and NXDisplayError()
is now renamed NXQueryDisplayError(). To verify if the display
is valid, NXQueryDisplayError() will now call the _NXDisplayEr-
rorPredicate function, or, if the predicate function is not set,
will simply check the value of the XlibDisplayIOError flag.
- Removed the NXGetCleanupParameters() and NXGetImageParameters()
interfaces and the remaining references to the unused display
buffer and image cleanup functions.
- Updated the NoMachine copyright notice to year 2006.
nxcompext-2.0.0-8
- Removed the unused screen parameter from XSetUnpackGeometry().
- NXSetUnpackGeometry() now fails if no visual is provided.
nxcompext-2.0.0-7
- Changed the LICENSE file to state that the software is only made
available under the version 2 of the GPL.
- Removed the misplaced DXPC copyright notices from the license.
They were copied from NXCOMP but they don't apply in any way to
NXCOMPEXT.
nxcompext-2.0.0-6
- Added the NXSetCacheParameters() request. It tells to the local
proxy how to handle the X requests, namely if the next requests
have to be stored in the memory cache, split in smal data chunks,
and in the case of images, saved on disk in the persistent image
cache. The request will affect all X messages, including plain
and packed images. It can be used to tell the proxy to discard
images coming from some selected operations, like GLX or XVideo.
nxcompext-2.0.0-5
- Added the NXGetFontParameters() request and reply. If the proxy
has been configured accordingly, the request returns the X font
path that can be set by the agent to tunnel the font server con-
nections through the NX link.
nxcompext-2.0.0-4
- Initial work on font server tunneling.
nxcompext-2.0.0-3
- Renamed the NXSetExposeEvents request to NXSetExposeParameters.
nxcompext-2.0.0-2
- Modified the configure and the makefiles to support the Cygwin
environment.
- Renamed Png.h to Pgn.h to avoid name clashes on Windows.
- The distclean target now removes the autom4te.cache directory.
nxcompext-2.0.0-1
- Opened the 2.0.0 branch based on nxcompext-1.5.0-20.
nxcompext-1.5.0-20
- Removed the code installing a SIGSEGV handler before trying to
clean an image in NXCleanImageInPlace().
nxcompext-1.5.0-19
- Added the NXUnsetLibraryPath() function to specify the behaviour
of the Popen() in the X server. If the _NXUnsetLibraryPath flag
is set, the Popen() will remove the LD_LIBRARY_PATH variable from
the environment before running the child process. This will cause
the X server to run the process (for example the keyboard initia-
lization utilities) by using the native system libraries, instead
of the libraries shipped with the NX environment.
nxcompext-1.5.0-18
- Moved the declarations of _NXEnable* and related structures from
Xlibint.h to NXlibint.h.
- Use the include files from nx-X11 if the nx-X11/include directory
is found. The previous configure checked the presence of nx-X11/
exports/include, that might not be built at the time this library
is compiled.
nxcompext-1.5.0-17
- Added the -fPIC GCC flag when compiling on AMD64 architectures.
- Removed all warnings when compiling with GCC4.
- Small changes to configure.in to have specific CFLAGS.
- Created a new configure using autoconf 2.59.
nxcompext-1.5.0-16
- Added the 'mode' field in the NXStartSplit() request. It determi-
nes the strategy that the proxy will adopt to handle the image.
If set to 'eager', the proxy will only split the messages whose
size exceeds the split threshold (the threshold can be found in
the NXGetControlParameters() reply). If mode is set to lazy, the
proxy will split any image that it is not able to find in its
cache.
The opcode and the two available modes are defined in NXproto.h,
currently:
#define NXSplitModeDefault 0
#define NXSplitModeEager 1
#define NXSplitModeLazy 2
- All requests related to image streaming now carry a 'resource' id.
The id is currently ignored by the proxy in the case of NXCommit-
Split() requests.
nxcompext-1.5.0-15
- Removed the NXSync() and NXKarma() operations, not used anymore
by the NX agents.
- Updated to comply with changes occurred in the numbering of the
notification events and in the interface to the image streaming
functions.
nxcompext-1.5.0-14
- Accounted for the missing xoffset field in clean-up of XYPixmaps.
nxcompext-1.5.0-13
- Added a 'commit' field in NXCommitSplit(). When zero, the remote
proxy will remove the message from the split store, without send-
ing the recomposed image to the X server.
nxcompext-1.5.0-12
- Added the NXContinueOnDisplayError() function to specify the be-
haviour of the Xlib I/O error handler. If the flag is set to true,
Xlib will simply return, instead of quitting the program. This
leaves to the application the responsibility of checking the sta-
te of the XlibDisplayIOError flag.
- Changed NXDisplayIsValid() to NXDisplayError() and inverted the
logic. Now the function returns true if the display pointer is
NULL or the XlibDisplayIOError flag is set.
- Added the NXForceDisplayError() function, to shutdown the display
descriptor and force Xlib to set the I/O error flag.
nxcompext-1.5.0-11
- Added -I../nx-X11/exports/include to CCINCLUDES in Makefile.in.
nxcompext-1.5.0-10
- Added FindLSB() to replace ffs() that may be not present on some
systems.
- Some cosmetic changes.
nxcompext-1.5.0-9
- Fixed a printf() that prevented the code to compile if TEST was
enabled.
nxcompext-1.5.0-8
- Implemented the NXLib interface for asynchronous handling of the
XGetInputFocus requests and replies.
nxcompext-1.5.0-7
- Removed the _NXFlushSize parameter. New agents run the NX trans-
port in-process, so we don't get any benefit from increasing the
display buffer size.
nxcompext-1.5.0-6
- Added a NXDisplayIsValid() to check that the display is not NULL
and that the descriptor was not shut down after an IOError. The
reason a function is needed for this is that the flags field is
only in Xlibint and it is not visible to Xlib applications.
nxcompext-1.5.0-5
- Added the NXGetCollect*Resource utility functions, returning the
first available small integer resource id that can be used in a
subsequent collect request.
nxcompext-1.5.0-4
- Added the NXNumberOfConnections constant.
nxcompext-1.5.0-3
- Implemented the NXLib interface for the asynchronous handling of
the XGrabPointer requests and replies.
- Solved an error in image cleaning that prevented the 8 bits-per-
pixel images to be completely cleaned. Due to the bug, only half
of the total lines were cleaned.
- Removed a bug that prevented the cleaning of XYPixmaps images of
bitmap unit 32 and byte order LSB.
- Renamed the NXImageCache variables to show they are global. They
are currently used in the nxagent code.
nxcompext-1.5.0-2
- Changed VERSION file.
nxcompext-1.5.0-1
- Opened the 1.5.0 branch.
nxcompext-1.4.1-1
- Removed the configure option --with-static. There are two options
now, --with-static-png and --with-static-jpeg, to offer a greater
degree of control on the resulting library.
- This version differs from the 1.4.0-3-KRY1 in the way that the con-
figure script is generated by GNU Autoconf 2.57, the same version
used for nxcomp.
- Opened the 1.4.1 branch.
nxcompext-1.4.0-3
- Updated the VERSION file to reflect the 1.4.0 status.
nxcompext-1.4.0-2
- Imported changes from the latest 1.3.2 development branch.
- The 1.4.0 branch already had a 1.4.0-1 version. The changes from
the 1.4.0-1 were up to date with the 1.3.2-2 version.
nxcompext-1.3.2-6
- Fixed problem with icons in KDE and Mozilla on SPARC Solaris. The
problem was related to cleaning of one-bit XYPixmaps on big-endian
hosts, where shift of the cleaning mask executed in the wrong di-
rection.
nxcompext-1.3.2-5
- Changes in Clean.c to compile on Solaris.
nxcompext-1.3.2-4
- Fixed a bug in clean image procedures for 1bit XYPixmaps. The bug
caused Mozilla to trash some transparent icons in web pages and
the toolbar.
- Added cleaning of the padding bytes at the end of the data chunk
inside XImage structure
- Implemented handling of SIGSEGV during cleanup in case of static
data.
- Moved image cleanup and masking code in new Clean.c and Mask.c
sources.
- Corrected few typos in NXCollectImage code.
nxcompext-1.3.2-2
- Imported 1.4.0-1 changes from the 1.4.0 development branch.
- Modified NXAllocColors to handle errors generated allocating
each requested color. A per-color result code is now returned
to the caller.
- Code cleanup in Png.h and Png.c.
nxcompext-1.3.2-1
- Opened the 1.3.2 branch.
nxcompext-1.3.1-2
- Removed the underline characters and added a colon in the
title of this ChangeLog to fully comply with format used in
the release notices.
nxcompext-1.3.1-1
- Opened the 1.3.1 branch.
nxcompext-1.3.0-18
- Added the _NXLostSequenceHandler function to let NX agents
suppress the error message and modify the default Xlib
behaviour when out-of-order sequence numbers are received.
Pointer to function is assigned to _NXLostSequenceFunction
in XlibInt.c.
- Original output buffer size in stock XFree86 is 2048. We try
to reduce context switches and help stream compression by
increasing the maximum size of the buffer 8192. _NXFlushSize
determines when the display buffer is actually flushed. It is
set by default to 4096 in XlibInt.c and set to 0 to use the
maximum available size at the time NXGetControlParameters()
is called.
nxcompext-1.3.0-17
- In handling of asynchronous GetProperty replies a warning
message was printed in session log when a null property was
stored in the state structure. This message is now printed
only if TEST is defined.
nxcompext-1.3.0-16
- Added asynchronous handling of GetProperty request and reply
by means of the NXCollectProperty and NXGetCollectedProperty
requests and the NXCollectPropertyNotify event.
nxcompext-1.3.0-15
- Added 4 new fields to the X_NXGetControlParameters reply.
nxcompext-1.3.0-14
- Added request X_NXFreeUnpack to free the resources allocated
by the remote proxy to unpack images for the given agent's
client
nxcompext-1.3.0-13
- Modified the following requests to carry the id of the
agent's client in the field resource:
- X_NXSetUnpackGeometry
- X_NXSetUnpackColormap
- X_NXSetUnpackAlpha
- X_NXPutPackedImage
nxcompext-1.3.0-11
- Modified the MIT-SHM initialization procedure to always send
all the 3 protocol requests also in the case of early failures.
nxcompext-1.3.0-10
- Added handling of X_NXSetUnpackAlpha request.
- It has been made possible to send both X_NXSetUnpackColormap
and X_NXSetUnpackAlpha messages with 0 entries to temporarily
disable use of the colormap or the alpha channel and free the
resources allocated by the remote proxy.
nxcompext-1.3.0-9
- Solved a compatibility problem when mixing proxy versions
1.2.2 and 1.3.0 due to the missing X_NXGetShmemParameters
request.
nxcompext-1.3.0-7
- Reduced the number of requests needed to setup the shared
segment at X server proxy from 4 to 3.
- Small changes to the shared memory interface to support
path X agent to X client proxy.
nxcompext-1.3.0-6
- Implemented initial support for MIT-SHM extension in the
network path between the X server proxy and the real X
server.
- Configure script now checks for the FreeBSD environment.
- New configure script generated using autoconf-2.57-3.
- Removed the XFree86 CCDEFINES from Makefile.in.
nxcompext-1.3.0-5
- Cosmetic changes.
- Started to convert configure.in to the new layout adopted
for nxcomp.
- Created file CHANGELOG.
nxcompext-1.3.0-4
- More fixes in image clean-up.
nxcompext-1.3.0-3
- Many fixes in image clean-up functions to handle differences
in endianess between client and X server.
nxcompext-1.3.0-2
- Modified configure.in to compile under Solaris.
nxcompext-1.3.0-1
- First 1.3.0 version based on nxcompext-1.2.2-12.

nxproxy-2.0.0-2
- Updated copyright to year 2006.
nxproxy-2.0.0-1
- Opened the 2.0.0 branch based on nxproxy-1.5.0-10.
nxproxy-1.5.0-10
- Added the JPEG, PNG and Z libraries to the linker when compiling
on Cygwin. GCC 3.3.x requires that these libraries are explicitly
given while this is not required since GCC 3.4.x.
- Created a new configure using autoconf 2.59.
nxproxy-1.5.0-9
- Removed provision for dynamically loading a different version of
the nxcomp library.
nxproxy-1.5.0-8
- Updated to reflect the new naming of the NX transport interfaces.
nxproxy-1.5.0-7
- Modified the Makefile.in to remove the *.out.* files generated by
Valgrind when running a 'make clean'.
- Modified the README files and removed files that were outdated.
nxproxy-1.5.0-6
- Removed the NX_FORCE_IDLE_PROXY stubs.
nxproxy-1.5.0-5
- This version has NX_FORCE_IDLE_PROXY undefined, so it should work
in a way that is compatible with the old nxproxy.
nxproxy-1.5.0-4
- This software is crafted by default to test the new integration
between nxcomp and nxssh. The process will stay idle and will
let nxssh create the proxy. Note that the session log will go to
'sshlog', not to 'session'. This will have to be fixed in nxcomp
in future versions.
- Removed the references to the "bind" functionality that is not
used in the current software.
nxproxy-1.5.0-3
- Added a NX_FORCE_IDLE_PROXY. If set, nxproxy will stay idle and
will not try to create a nxcomp proxy. This is used for testing
the new in-process nxcomp functionalities with the development
versions of nxclient and nxssh software.
nxproxy-1.5.0-2
- Small changes to this file.
nxproxy-1.5.0-1
- Opened the 1.5.0 branch.
nxproxy-1.4.1-1
- Opened the 1.4.1 branch.
nxproxy-1.4.0-3
- We were lucky. We found a machine where nxproxy failed exactly
in the same way described by multiple users in their reports.
The error was the same ('dlopen: win32 line 126') and neither
rebasing the Cygwin DLLs or removing all the other Cygwin li-
braries worked. So the problem had necessarily to be in a bug-
gy Cygwin dlopen() implementation. To solve this I had to make
changes to the nxproxy code on Windows, so it links to nxcomp
at compile time in the way specified below. As far as I can
tell, any other way fails. This seems to be another Cygwin bug:
the linker says that everything is OK but then the executable
can't be run. Both the Cygwin's bash and the command.com say
'Permission denied'.
LIBS = -L../nxcomp -lstdc++ -Wl,-e,_mainCRTStartup -lXcomp \
-lcygipc -static -lpng -static -ljpeg -lz
nxproxy-1.4.0-2
- Added a Binder class invoked when calling proxy with -B option.
It would serve as a replacement of the modifications I'm doing
in nxssh. The class is just a framework and the implementation
is unfinished.
- Solved a potential problem in Main.c with NXExit() being called
after the dlclose(). This was unlikely to happen as proxy never
returns.
nxproxy-1.4.0-1
- Opened the 1.4.0 branch.
nxproxy-1.3.2-1
- Opened the 1.3.2 branch.
nxproxy-1.3.1-2
- Removed the underline characters and added a colon in the
title of this ChangeLog to fully comply with format used in
the release notices.
nxproxy-1.3.1-1
- Opened the 1.3.1 branch.
nxproxy-1.3.0-7
- Added a check on the OS version when running on MacOS/X.
Versions 10.2 and 10.3 differ in the way names are mangled.
- Fixed error detection on dlsym(). The previous code was not
able to correctly identify missing symbols.
nxproxy-1.3.0-6
- Modified configure.in to compile under FreeBSD.
nxproxy-1.3.0-5
- Fixed a (further) compilation problem under Cygwin.
nxproxy-1.3.0-4
- New nxproxy is able to load libXcomp by dlopen() under
Cygwin. This simplifies both code in Main.c and the
configure.in script.
- Changed configure.in to not link with -mwindows under
Cygwin. Linking with -mwindows prevented stderr to be
correctly output when running nxproxy on a console.
nxproxy-1.3.0-3
- Changed configure.in to first check for nx-X11 includes
and libraries. Added "/usr/openwin/bin/makedepend" to
path searched for the executable.
nxproxy-1.3.0-2
- Small cleanup in configure.in. A new configure script has
been generated using autoconf-2.57-3.
nxproxy-1.3.0-1
- Updated internal version, so this release tries to load
libXcomp version 1.3.0.

README
------
1. To compile:
> tar zxvf nxproxy-X.Y.Z-N.tar.gz
> cd nxproxy
> ./configure
> make
You'll have to run gmake under Solaris.
2. The 'make install' target is not currently supported
in the Makefile, but it should be simple to fix.

README-IPAQ
-----------
1. Install a cross-compiler for ARM. You can find detailed
informations at:
http://www.ailis.de/~k/knowledge/crosscompiling/toolchain.php
There are also binaries needed to install the cross-compiler.
2. Configure and compile nxproxy using:
$ ./configure --with-ipaq
$ make
After compilation type:
$ arm-linux-strip nxproxy
3. You need libXcomp.so to run nxproxy. Be sure you include the
library in your LD_LIBRARY_PATH. For example, you can run:
> export LD_LIBRARY_PATH $HOME/NX/nxcomp
> nxproxy -S localhost:8
4. The package nxscripts contains many examples of NX usage that
you can modify to suit your needs.
