# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_COMPILE_AND_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the current language's compiler
|
||||
# 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 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.
|
||||
#
|
||||
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.
