# SYNOPSIS

#
|
||||
# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
|
||||
# added in between.
|
||||
#
|
||||
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
|
||||
# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
|
||||
# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
|
||||
# FLAG.

# SYNOPSIS
|

#
|
||||
# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
|
||||
#
|
||||
# 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.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for baseline language coverage in the compiler for the C++11
|
||||
# standard; if necessary, add switches to CXXFLAGS to enable support.
|
||||
#
|
||||
# The first argument, if specified, indicates whether you insist on an
|
||||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
|
||||
# -std=c++11). If neither is specified, you get whatever works, with
|
||||
# preference for an extended mode.
|
||||
#
|
||||
# The second argument, if specified 'mandatory' or if left unspecified,
|
||||
# indicates that baseline C++11 support is required and that the macro
|
||||
# should error out if no mode with that support is found. If specified
|
||||
# 'optional', then configuration proceeds regardless, after defining
|
||||
# HAVE_CXX11 if and only if a supporting mode is found.
