URL: <http://savannah.gnu.org/patch/?7985> Summary: Feature additions to AX_CXX_COMPILE_STDCXX_11 macro Project: GNU Autoconf Archive Submitted by: None Submitted on: Thu 28 Mar 2013 05:35:19 PM UTC Priority: 3 - Low Status: None Assigned to: None Originator Email: address@hidden Open/Closed: Open Discussion Lock: Any _______________________________________________________ Details: The attached version of ax_cxx_compile_stdcxx_11.m4 has several changes: The C++11 test code includes the "auto" keyword AC_LANG_PUSH/POP rather than AC_LANG_ASSERT makes it more robust to use An optional second argument makes it possible to test for C++11 and return the result with an AC_DEFINE/AC_SUBST/AM_CONDITIONAL without erroring out if support is not found. This new version should be nearly backwards-compatible with the old; the obvious exception being when compilers which implement a subset of C++11 not including "auto" are used with codes for which that subset would have been sufficient. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Thu 28 Mar 2013 05:35:19 PM UTC Name: ax_cxx_compile_stdcxx_11.m4 Size: 4kB By: None <http://savannah.gnu.org/patch/download.php?file_id=27704> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/patch/?7985> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
