# # SYNOPSIS
|
|
# #
|
|
# # AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
|
|
# #
|
|
# # 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.
