# SYNOPSIS
|
||||
#
|
||||
# AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# For every FLAG1, FLAG2 it is checked whether the compiler works with the
|
||||
# flag. If it does, the flag is added FLAGS-VARIABLE
|
||||
#
|
||||
# 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.
|
||||
#
|
||||
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
|
||||
#
|
||||
# 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_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])

#

# Check whether the given FLAG works with the current language's compiler

#
|

# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|

# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.
