# SYNOPSIS
|
|
#
|
|
# AX_CFLAGS_AIX_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# AX_CFLAGS_AIX_OPTION(-qubicle) would show a message as like "checking
|
|
# CFLAGS for aix/cc -qubicle ... yes" and adds the optionflag to CFLAGS if
|
|
# it is understood. You can override the shellvar-default of CFLAGS of
|
|
# course. The order of arguments stems from the explicit macros like
|
|
# AX_CFLAGS_WARN_ALL.
|
|
#
|
|
# The cousin AX_CXXFLAGS_AIX_OPTION would check for an option to add to
|
|
# CXXFLAGS - and it uses the autoconf setup for C++ instead of C (since it
|
|
# is possible to use different compilers for C and C++).
|
|
#
|
|
# The macro is a lot simpler than any special AX_CFLAGS_* macro (or
|
|
# ax_cxx_rtti.m4 macro) but allows to check for arbitrary options.
|
|
# However, if you use this macro in a few places, it would be great if you
|
|
# would make up a new function-macro and submit it to the ac-archive.
|
|
#
|
|
# - $1 option-to-check-for : required ("-option" as non-value)
|
|
# - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case)
|
|
# - $3 action-if-found : add value to shellvariable
|
|
# - $4 action-if-not-found : nothing
|
|
#
|
|
# note: in earlier versions, $1-$2 were swapped. We try to detect the
|
|
# situation and accept a $2=~/-/ as being the old option-to-check-for.
|
|
#
|
|
# see also: AX_CFLAGS_GCC_OPTION for the widely used original variant.
