--- Comment #13 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > Did you try to get gnat1 built without -static-libgcc ? How am I supposed to do that? I have used the same clean configure ../p_work/configure --prefix=/opt/gcc/gcc8p-247298p1 --enable-languages=c,c++,lto,fortran,ada,objc,obj-c++ --with-gmp=/opt/mp-new --with-system-zlib --enable-checking=release --with-isl=/opt/mp-new --enable-lto --enable-plugin --with-arch=corei7 --with-cpu=corei7 and bootstrap for r247298 (bootstraps) and r247302 (fails). The bootstrap compiler is gcc version 8.0.0 20170425 (experimental) [trunk revision 247256] configured with ../_clean/configure --prefix=/opt/gcc/gcc8a --enable-languages=c,c++,fortran,ada,lto --with-gmp=/opt/mp-new --with-system-zlib --enable-checking=release --with-isl=/opt/mp-new --enable-lto --enable-plugin
