Why do you need "i686-elf" rather than e.g. i686-unknown-linux-gnu ? What are you actually trying to do in the end? > So, first I created native compiler Native to what?

The instructions you said you're following don't do this. I no longer help people who install gmp, mpfr and mpc manually and ask for help. > #GCC > $gcc_src/configure > --prefix="/home/ragnar/cpp-tools/compiler/linux32/gcc" > --target=i686-elf --enable-32bit --disable-64bit > --enable-languages="c,c++" --disable-multilib --enable-libssp > --enable-threads=posix --disable-nls --disable-shared > --with-gmp="/home/ragnar/cpp-tools/compiler/linux32/gcc" > --with-mpfr="/home/ragnar/cpp-tools/compiler/linux32/gcc" > --with-mpc="/home/ragnar/cpp-tools/compiler/linux32/gcc" > --enable-checking=release --enable-lto > --enable-version-specific-runtime-libs > make all-gcc > make all-target-libgcc Where is the --without-headers option that the wiki.osdev.org instructions say to use? Why are you surprised it doesn't work if you don't follow the instructions properly?
