--- Comment #57 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Jürgen Reuter from comment #56) > I tried the fix, but now I get another error: > /libstdc++-v3/../libgcc > -I/usr/local/packages/gcc_9.0_fixincl/_build/x86_64-apple-darwin18.5.0/i386/ > libstdc++-v3/include/x86_64-apple-darwin18.5.0 > -I/usr/local/packages/gcc_9.0_fixincl/_build/x86_64-apple-darwin18.5.0/i386/ > libstdc++-v3/include > -I/usr/local/packages/gcc_9.0_fixincl/libstdc++-v3/libsupc++ -std=gnu++17 > -D_GLIBCXX_SHARED -fno-implicit-templates -Wall -Wextra -Wwrite-strings > -Wcast-qual -Wabi=2 -fdiagnostics-show-location=once -ffunction-sections > -fdata-sections -frandom-seed=fs_dir.lo -fimplicit-templates -g -O2 -m32 -c > ../../../../../../libstdc++-v3/src/c++17/fs_dir.cc -fno-common -DPIC > -D_GLIBCXX_SHARED -o fs_dir.o > ../../../../../../libstdc++-v3/src/c++17/fs_ops.cc:31:10: fatal error: > filesystem: No such file or directory > 31 | #include <filesystem> > | ^~~~~~~~~~~~ > compilation terminated. so, to be clear, it worked for the 8.x branch and you see a different issue for trunk. what stage is this at, and what version of trunk is it?
