Hi there, So I compiled gcc-7.1.0 with in-tree binutils-2.28 with lto support: ../srcdir/configure --enable-languages=c,c++,fortran,lto \ --enable-lto=yes \ --prefix=<prefix> \ --enable-host-shared \ --enable-shared \ --with-gnu-as \ --with-gnu-ld \ --enable-gold \ --enable-plugins \ --with-plugin-ld=gold \ --with-fpmath=avx Everything compiles and installs itself properly. But strangely enough, I get that error when trying to use -fuse-linker-plugin: gcc: error: -fuse-linker-plugin is not supported in this configuration Is there anything obvious I did wrong?
