--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> --- The build works for me just fine on sparc-sun-solaris2.11. I've also fired one off on sparc64-unknown-linux-gnu which worked just as well. It was a rough ride, however, with the build aborting with xgcc: fatal error: cannot execute '/var/gcc/regression/master/6.4.0-gcc-gas-gld/build/./gcc/cc1plus': posix_spawn: Bad address several times. When I ran make under strace -f, however, the build worked just fine. Quite ugly, actually. That said, those specializations of std::to_string live in libstdc++-v3/include/bits/basic_string.h. The floating point ones are guarded by _GLIBCXX_USE_C99_STDIO. In my build, sparc64-unknown-linux-gnu/libstdc++-v3/config.h has #define _GLIBCXX11_USE_C99_STDIO 1 #define _GLIBCXX98_USE_C99_STDIO 1 If yours does not, you need to check config.log to find out what's wrong. -- You are receiving this mail because: You are on the CC list for the bug.
