--- Comment #1 from Sam James <sjames at gcc dot gnu.org> --- Can you still reproduce this after r15-4345-g384faebde257b0? (In reply to Martin Jambor from comment #0) > Starting with commit r15-4286-gc397a8c12296b7 (Jakub Jelinek: > libcpp, genmatch: Use gcc_diag instead of printf for libcpp > diagnostics), I cannot build GCC when configured as: > > ../src/configure --enable-languages=c,c++ --disable-bootstrap > --enable-coverage=opt --enable-host-shared > > which we use (with more languages enabled) to generate > https://gcc.opensuse.org/gcc-lcov/ (I admit I do not know why we use > --enable-host-shared or if it is strictly necessary). > JIT needs it, at least.
