# SYNOPSIS
|
||||
#
|
||||
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for baseline language coverage in the compiler for the specified
|
||||
# version of the C++ standard. If necessary, add switches to CXX and
|
||||
# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
|
||||
# or '14' (for the C++14 standard).
|
||||
#
|
||||
# The second 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 third argument, if specified 'mandatory' or if left unspecified,
|
||||
# indicates that baseline support for the specified C++ standard 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_CXX${VERSION} if and only if a
|
||||
# supporting mode is found.
