# DESCRIPTION
|

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

#
|

# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on

#
|

# 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

|

# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the current language's
|
||||
# preprocessor 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 preprocessor's default
|
||||
# flags when the check is done. The check is thus made with the flags:
|
||||
# "CPPFLAGS EXTRA-FLAGS FLAG". This can for example be used to force the
|
||||
# preprocessor to issue an error when a bad flag is given.
|
||||
#
|
||||
# INPUT gives an alternative input source to AC_PREPROC_IFELSE.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{COMPILE,LINK}_FLAG.

#
|

# AX_SAVE_FLAGS(mypackage)

# CPPFLAGS="-Imypackagespath ${CPPFLAGS}"
