GCC tools, libstdc++ pass 1 Libstdc++ is part of the GCC sources. You should first unpack the GCC tarball and change to the gcc-&gcc-version; directory. Create a separate build directory for libstdc++ and enter it: mkdir -v build cd build Prepare libstdc++ for compilation: ../libstdc++-v3/configure \ --host=$LFS_TGT \ --build=$(../config.guess) \ --prefix=/usr \ --disable-multilib \ --disable-nls \ --disable-libstdcxx-pch \ --with-gxx-include-dir=/tools/$LFS_TGT/include/c++/&gcc-version; --host=... Specifies that the cross compiler we have just built should be used instead of the one in /usr/bin. --disable-libstdcxx-pch This switch prevents the installation of precompiled include files, which are not needed at this stage. --with-gxx-include-dir=/tools/$LFS_TGT/include/c++/&gcc-version; This specifies the installation directory for include files. Because libstdc++ is the standard C++ library for LFS, this directory should match the location where the C++ compiler ($LFS_TGT-g++) would search for the standard C++ include files. In a normal build, this information is automatically passed to the libstdc++ configure options from the top level directory. In our case, this information must be explicitly given. The C++ compiler will prepend the sysroot path $LFS (specified building GCC pass 1) to the include file search path, so it will actually search in $LFS/tools/$LFS_TGT/include/c++/&gcc-version;. The combination of the DESTDIR variable (in the make install command below) and this switch ensures to install the headers there. Compile libstdc++ by running: make Install the library: make DESTDIR=$LFS install
