Bug 607620 – <sys-devel/gcc-6.0: c++11 mode does not work properly on FreeBSD

• Product: Gentoo/Alt
• Status: RESOLVED OBSOLETE

[Description Yuta SATOH 2017-01-29 11:41:46 UTC]

-std=c++11 is required for llvm and clang.

test.cpp
#include <string>

int main() {
        std::to_string(1);
        return 0;
}

# g++-5.4.0 -std=c++11 test.cpp
test.cpp: In function 'int main()':
test.cpp:4:9: error: 'to_string' is not a member of 'std'
         std::to_string(1);
         ^
# g++-6.3.0 -std=c++11 test.cpp
#
Note, Compile is successful with gcc-6.3.0.

@toolchain, any idea how to fix it? FWICS, passing -D_GLIBCXX_USE_C99 works around the problem, so maybe there's an easy trick to make it enable that for -std=c++11?

*-fbsd is gone.
