I can't get the linker plugin to work. g++: error: -fuse-linker-plugin is not supported in this configuration I build a userland binutils and gcc with dependencies. I've tried gold and bfd. Does anyone see anything obvoiusly wrong with this? cd gcc-4.7.0 ./configure --with-gmp=$INSTALLATION/gmp-4.3.2 --with-mpfr=$INSTALLATION/mpfr-2.4.2 --with-mpc=$INSTALLATION/mpc-0.8.2 --with-ppl=$INSTALLATION/ppl-0.11 \ --enable-cloog-backend=isl --with-cloog=$INSTALLATION/cloog-0.16.2 --prefix=$INSTALLATION/gcc-4.7.0 \ --enable-languages=c,c++ \ --enable-lto --with-libelf=$INSTALLATION/libelf-0.8.12 --enable-gold make install cd binutils-2.22 ./configure --enable-gold --enable-plugins --enable-lto --with-gmp=$INSTALLATION/gmp-4.3.2 --with-mpfr=$INSTALLATION/mpfr-2.4.2 --with-mpc=$INSTALLATION/mpc-0.8.2 \ --with-ppl=$INSTALLATION/ppl-0.11 --enable-cloog-backend=isl --with-cloog=$INSTALLATION/cloog-0.16.2 --prefix=$INSTALLATION/binutils-2.22 \ --disable-werror make all-gold Do I have the order right? Someone mentioned an in-tree build to build binutils and gcc together. Is there some doc explaining how to do that? GCC's HAVE_LTO_PLUGIN=0 in ./host-i686-pc-linux-gnu/gcc/auto-host.h. Does that mean it won't ever work or I just need a better linker at runtime? Chris
