# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_PREPROC_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
# AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
|
||||
# AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
|
||||
# AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the current language's
|
||||
# preprocessor/compiler/linker, or whether they give 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 current language's default
|
||||
# flags (e.g. CFLAGS) when the check is done. The check us thus made
|
||||
# with the following flags: "CFLAGS EXTRA-FLAGS FLAG". EXTRA-FLAGS can
|
||||
# for example be used to force the compiler to issue an error when a bad
|
||||
# flag is given.
|
||||
#
|
||||
# AX_APPEND_FLAG appends the FLAG to the FLAG-VARIABLE shell variable or
|
||||
# the current language's flags if not specified. FLAG is not added to
|
||||
# FLAG-VARIABLE if it is already in the shell variable.
|
||||
#
|
||||
# AX_APPEND_COMPILE_FLAGS checks for each FLAG1, FLAG2, etc. using
|
||||
# AX_CHECK_COMPILE_FLAG and if the check is successful the flag is added
|
||||
# to the appropriate FLAGS variable with AX_APPEND_FLAG. The
|
||||
# FLAGS-VARIABLE and EXTRA-FLAGS arguments are the same as in the other
|
||||
# macros. AX_APPEND_LINK_FLAGS does the same for linker flags.
|
||||
#
|
||||
# NOTE: Based on AX_CHECK_COMPILER_FLAGS and AX_CFLAGS_GCC_OPTION.
