GCC tools, libstdc++ pass 2 Libstdc++ is part of the GCC sources. You should first unpack the GCC tarball and change to the gcc-&gcc-version; directory. Create a link which exists when building libstdc++ in the gcc tree: ln -s gthr-posix.h libgcc/gthr-default.h Create a separate build directory for libstdc++ and enter it: mkdir -v build cd build Prepare libstdc++ for compilation: ../libstdc++-v3/configure \ CXXFLAGS="-g -O2 -D_GNU_SOURCE" \ --prefix=/usr \ --disable-multilib \ --disable-nls \ --disable-libstdcxx-pch ../libstdc++-v3/configure \ CXXFLAGS="-g -O2 -D_GNU_SOURCE" \ --prefix=/usr \ --enable-multilib \ --disable-nls \ --disable-libstdcxx-pch \ --host=x86_64-lfs-linux-gnu CXXFLAGS="-g -O2 -D_GNU_SOURCE" These flags are passed by the top level Makefile when doing a full build of GCC. --disable-libstdcxx-pch This switch prevents the installation of precompiled include files, which are not needed at this stage. --enable-multilib This switch is set by default but it is added here explicitly for documentary purpose. The libstdc++ libraries will be built for every arch (m64, m32, mx32) which are made available in . --host=x86_64-pc-linux-gnu Since up to now the cross-compile tools are used. This switch is set to ensure that the headers used for multilib are placed in correct locations where the final system can pick them up. Compile libstdc++ by running: make Install the library: make install
