5.8. Libstdc++-4.8.2

Libstdc++ is the standard C++ library. It is needed for the correct operation of the g++ compiler.

Approximate build time: 0.4 SBU
Required disk space: 734 MB

5.8.1. Installation of Target Libstdc++



Libstdc++ is part of the GCC sources. You should first unpack the GCC tarball and change to the gcc-4.8.2 directory.

Create a directory for Libstdc++ and enter it:

mkdir -pv ../gcc-build
cd ../gcc-build

Prepare Libstdc++ for compilation:

../gcc-4.8.2/libstdc++-v3/configure \
    --host=$LFS_TGT                 \
    --prefix=/tools                 \
    --disable-multilib              \
    --disable-shared                \
    --disable-nls                   \
    --disable-libstdcxx-threads     \
    --disable-libstdcxx-pch         \

The meaning of the configure options:


Indicates to use the cross compiler we have just built instead of the one in /usr/bin.


Since we have not built the thread C library, the C++ one cannot be built as well.


This switch prevents the installation of precompiled include files, which are not needed at this stage.


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:


Install the library:

make install
