From 608cee69658faa668c31fa41e15a62fbf7ad5cd1 Mon Sep 17 00:00:00 2001 From: Vadim Zeitlin Date: Sun, 20 Mar 2016 16:56:50 +0100 Subject: [PATCH 1/9] Fix C++11 check when --with-cxx=11 is used AX_CXX_COMPILE_STDCXX() macro does not define HAVE_CXX11 when C++11 is required (and not optional, as with --enable-cxx11), so the build was broken when --with-cxx=11 was used under OS X as -stdlib=libc++ was not used. Fix this and also leave only a single AX_CXX_COMPILE_STDCXX() check for C++11, this saves us ~1000 lines in configure. --- configure | 2931 +++++++++++++++++--------------------------------- configure.in | 12 +- 2 files changed, 989 insertions(+), 1954 deletions(-) diff --git a/configure b/configure index 0b45fb4c8f..b3968a85bf 100755 --- a/configure +++ b/configure @@ -15139,1958 +15139,988 @@ fi if test -n "$wxWITH_CXX"; then case "$wxWITH_CXX" in 11) + ax_cxx_compile_cxx11_required=false + ac_ext=cpp +ac_cpp='$CXXCPP $CPPFLAGS' +ac_compile='$CXX -c $CXXFLAGS $CPPFLAGS conftest.$ac_ext >&5' +ac_link='$CXX -o conftest$ac_exeext $CXXFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5' +ac_compiler_gnu=$ac_cv_cxx_compiler_gnu + ac_success=no + { $as_echo "$as_me:${as_lineno-$LINENO}: checking whether $CXX supports C++11 features by default" >&5 +$as_echo_n "checking whether $CXX supports C++11 features by default...
