Hello, This is my first post in this mailing list, so I apologize if I do anything wrong. I'm working on a hobby operating system and, as part of making apps for it, I'm trying to port gcc to it. To be clear: I already have my cross compiler, I just want to make gcc run inside the OS. However, gcc doesn't seem to find cc1, and when I look into the searchdirs it shows relative paths (prepended with ".."), which means it would never find cc1. I'm configuring GCC with the following: configure --host=x86_64-toast --prefix=/usr --target=x86_64-toast --with-sysroot=/ --with-build-sysroot=<my sysroot dir> --enable-languages=c,c++ --enable-initfini-array --disable-multilib --disable-nls --enable-lto --with-system-zlib CFLAGS=-O2 CXXFLAGS=-O2 Then running make all-gcc all-target-libgcc all-target-libcstdc++-v3 Is there some sort of setting I could use to change the searchdirs to absolute? Thank you very much for your time.
