--- Comment #7 from Rich Townsend <townsend at astro dot wisc.edu> --- (In reply to Andrew Pinski from comment #6) > GCC 13 won't build with anything older than GCC 4.8.x as documented at > https://gcc.gnu.org/install/prerequisites.html (which is right now for the > trunk but that requirement has not changed yet). The plot thickens -- I misidentified the compiler, here's the correct id: [user@0ec987449fdf gcc-build]$ x86_64-pc-linux-gnu-g++ -v Using built-in specs. COLLECT_GCC=x86_64-pc-linux-gnu-g++ COLLECT_LTO_WRAPPER=/opt/bootstrap/mesasdk/bin/../libexec/gcc/x86_64-pc-linux-gnu/12.1.0/lto-wrapper Target: x86_64-pc-linux-gnu Configured with: /home/user/sdk2-tmp/build/gcc/configure CC= CXX= --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=x86_64-pc-linux-gnu --prefix=/home/user/sdk2-tmp/mesasdk --with-gmp=/home/user/sdk2-tmp/mesasdk --with-mpfr=/home/user/sdk2-tmp/mesasdk --with-mpc=/home/user/sdk2-tmp/mesasdk --enable-languages=c,c++,fortran --disable-multilib --disable-nls --disable-libsanitizer --enable-clocale=generic Thread model: posix Supported LTO compression algorithms: zlib gcc version 12.1.0 (GCC) So, 12.1.0 should be perfectly capable of building 13.1, right?
