GCC tools, libstdc++ Libstdc++ is part of the GCC sources. You should first unpack the GCC tarball and change to the gcc-&gcc-version; directory. Create a directory for Libstdc++ and enter it: mkdir -v ../gcc-build cd ../gcc-build Prepare Libstdc++ for compilation: ../gcc-&gcc-version;/libstdc++-v3/configure \ --host=$LFS_TGT \ --prefix=/tools \ --disable-multilib \ --disable-nls \ --disable-libstdcxx-threads \ --disable-libstdcxx-pch \ --with-gxx-include-dir=/tools/$LFS_TGT/include/c++/&gcc-version; --host=... Indicates to use the cross compiler we have just built instead of the one in /usr/bin. --disable-libstdcxx-threads Since we have not yet built the C threads library, the C++ one cannot be built either. --disable-libstdcxx-pch This switch prevents the installation of precompiled include files, which are not needed at this stage. --with-gxx-include-dir=/tools/$LFS_TGT/include/c++/&gcc-version; This is the location where the standard include files are searched by the C++ compiler. In a normal build, this information is automatically passed to the Libstdc++ configure options from the toplevel directory. In our case, this information must be explicitly given. Compile libstdc++ by running: make Install the library: make install
