# AX_AM_JOBSERVER([default_value])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Enables the use of make's jobserver for the purpose of parallel building
|
||||
# by passing the -j option to make.
|
||||
#
|
||||
# The option --enable-jobserver is added to configure which can accept a
|
||||
# yes, no, or an integer. The integer is the number of separate jobs to
|
||||
# allow. If 'yes' is given, then the is assumed to be one more than the
|
||||
# number of CPUs (determined through AX_COUNT_CPUS). If the value of no is
|
||||
# given, then the jobserver is disabled. The default value is given by the
|
||||
# first argument of the macro, or 'yes' if the argument is omitted.
|
||||
#
|
||||
# This macro makes use of AX_AM_MACROS, so you must add the following line
|
||||
#
|
||||
# @INC_AMINCLUDE@
|
||||
#
|
||||
# to your Makefile.am files.

#
|

# DESCRIPTION
|

#
|
||||
# For every FLAG1, FLAG2 it is checked whether the compiler works with the
|

|
||||
#
|
||||
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
|
||||
# CFLAGS) is used. During the check the flag is always added to the
|
||||
# current language's flags.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the current language's default
|
||||
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
||||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
||||
# force the compiler to issue an error when a bad flag is given.
|
||||
#
|
||||
# NOTE: This macro depends on the AX_APPEND_FLAG and
|
||||
# AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
|
||||
# AX_APPEND_LINK_FLAGS.

# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_LIBRARY(VARIABLE-PREFIX, HEADER-FILE, LIBRARY-FILE,
|
||||
# [ACTION-IF-FOUND], [ACTION-IF-NOT_FOUND])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Provides a generic test for a given library, similar in concept to the
|
||||
# PKG_CHECK_MODULES macro used by pkg-config.
|
||||
#
|
||||
# Most simplest libraries can be checked against simply through the
|
||||
# presence of a header file and a library to link to. This macro allows to
|
||||
# wrap around the test so that it doesn't have to be recreated each time.
|
||||
#
|
||||
# Rather than define --with-$LIBRARY arguments, it uses variables in the
|
||||
# same way that PKG_CHECK_MODULES does. It doesn't, though, use the same
|
||||
# names, since you shouldn't provide a value for LIBS or CFLAGS but rather
|
||||
# for LDFLAGS and CPPFLAGS, to tell the linker and compiler where to find
|
||||
# libraries and headers respectively.
|
||||
#
|
||||
# If the library is find, HAVE_PREFIX is defined, and in all cases
|
||||
# PREFIX_LDFLAGS and PREFIX_CPPFLAGS are substituted.
|
||||
#
|
||||
# Example:
|
||||
#
|
||||
# AX_CHECK_LIBRARY([LIBEVENT], [event.h], [event], [],
|
||||
# [AC_MSG_ERROR([Unable to find libevent])])

# SYNOPSIS

#
|
||||
# AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the linker or gives an error.
|
||||
# (Warnings, however, are ignored)
|
||||
#
|
||||
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
||||
# success/failure.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the linker's default flags
|
||||
# when the check is done. The check is thus made with the flags: "LDFLAGS
|
||||
# EXTRA-FLAGS FLAG". This can for example be used to force the linker to
|
||||
# issue an error when a bad flag is given.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.

# AX_CREATE_GENERIC_CONFIG [(PACKAGEnlibs [, VERSION])]

#
|

# DESCRIPTION
|
||||
#
|
||||
# Creates a generic PACKAGE-config file that has all the things that you
|
||||
# want, hmm, well, atleast it has --cflags, --version, --libs. Ahhm, did
|
||||
# you see ax_path_generic in the autoconf-archive? ;-)
|
||||
#
|
||||
# this macros saves you all the typing for a pkg-config.in script, you
|
||||
# don't even need to distribute one along. Place this macro in your
|
||||
# configure.ac, et voila, you got one that you want to install.
|
||||
#
|
||||
# oh, btw, if the first arg looks like "mylib -lwhat' then it will go to
|
||||
# be added to the --libs, and mylib is extracted.
|
||||
#
|
||||
# the defaults: $1 = $PACKAGE $LIBS $2 = $VERSION there is also an
|
||||
# AC_SUBST(GENERIC_CONFIG) that will be set to the name of the file that
|
||||
# we did output in this macro. Use as:
|
||||
#
|
||||
# install-exec-local: install-generic-config
|

#
|
||||
# install-generic-config:
|

# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro figures out how to build C programs using POSIX threads. It
|
||||
# sets the PTHREAD_LIBS output variable to the threads library and linker
|
||||
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
|
||||
# flags that are needed. (The user can also force certain compiler
|
||||
# flags/libs to be tested by setting these environment variables.)
|
||||
#
|
||||
# Also sets PTHREAD_CC to any special C compiler that is needed for
|
||||
# multi-threaded programs (defaults to the value of CC otherwise). (This
|
||||
# is necessary on AIX to use the special cc_r compiler alias.)
|
||||
#
|
||||
# NOTE: You are assumed to not only compile your program with these flags,
|
||||
# but also link it with them as well. e.g. you should link with
|
||||
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
|
||||
#
|
||||
# If you are only building threads programs, you may wish to use these
|
||||
# variables in your default LIBS, CFLAGS, and CC:
|
||||
#
|
||||
# LIBS="$PTHREAD_LIBS $LIBS"
|
||||
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
||||
# CC="$PTHREAD_CC"
|
||||
#
|
||||
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
|
||||
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
|
||||
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
||||
#
|
||||
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
|
||||
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
|
||||
# PTHREAD_CFLAGS.
|
||||
#
|
||||
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
|
||||
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
|
||||
# is not found. If ACTION-IF-FOUND is not specified, the default action
|
||||
# will define HAVE_PTHREAD.
|
||||
#
|
||||
# Please let the authors know if this macro fails on any platform, or if
|
||||
# you have any other suggestions or comments. This macro was based on work
|
||||
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
|
||||
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
|
||||
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
|
||||
# grateful for the helpful feedback of numerous users.

# AX_TLS([action-if-found], [action-if-not-found])
|

#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Provides a test for the compiler support of thread local storage (TLS)
|
||||
# extensions. Defines TLS if it is found. Currently knows about GCC/ICC
|
||||
# and MSVC. I think SunPro uses the same as GCC, and Borland apparently
|
||||
# supports either.

# DESCRIPTION
|

#
|
||||
# With the advent of Apple Xcode v5.0, the old tool sets are missing from

# the distribution. The provided "gcc" executable wrapper accepts the

# "-pthread" flag, and passes it to the underlying "clang" which chokes

# on it. This script checks the version of the gcc executable to see if
|

# it reports it is really "clang".
|
||||
#
|
||||
# The value is placed in the wolfssl_darwin_clang variable.
