## Makefile variables that must be defined in this file

|
# @param[out] $(BUILD) Set here for release or debug
|
|
BUILD:=release ##< Release build strips binary and optimizes
|
|
#BUILD:=debug ##< Debug build keeps debug symbols and disables compiler optimizations. Assembly language optimizations remain enabled

## Makefile variables that are read by this file.
|
|
# @param[in] $(MATRIXSSL_ROOT) Must be set to root MatrixSSL directory
|
|
# @param[in] $(CC) Used to determine the target platform, which will differ
|
|
# from host if cross compiling.
|
|
# @param[in] $(CPU) If set, should be the target cpu for the compiler,
|
|
# suitable for the '-mcpu=' flag. See 'gcc --help=target' for valid values.
|
|
# @param[in] $(SRC) List of source files to be compiled. Used to make $(OBJS),
|
|
# the list of object files to build.
|
|
|
|
#-------------------------------------------------------------------------------
|
|
## Makefile variables that are modified by this file
|
|
# @param[in,out] $(CFLAGS) Appended with many options as determined by this file, to be passed to compiler
|
|
# @param[in,out] $(LDFLAGS) Appended with many options as determined by this file, to be passed to linker
|

#-------------------------------------------------------------------------------
|
|
## Makefile variables that are created by this file
|
|
# @param[out] $(OSDEP) Set to platform code directory (./core/$OSDEP/osdep.c), based on $(CC)
|
|
# @param[out] $(CCARCH) Set to compiler's target architecture, based on $(CC)
|
|
# @param[out] $(STRIP) Set to the executable to use to strip debug symbols from executables
|
|
# @param[out] $(STROPS) Human readable description of relevant MatrixSSL compile options.
|
|
# @param[out] $(O) Set to the target platform specific object file extension
|
|
# @param[out] $(A) Set to the target phatform specific static library (archive) file extension
|
|
# @param[out] $(E) Set to the target platform specific executable file extension
|
|
# @param[out] $(OBJS) Set to the list of objects that is to be built
|
