GNU Compiler Collection - LibStdC++

Name: libstdc++
Summary: The C++ language runtime libraries
License: GPL v3.0+
Version: 15.2.0
URL: https://ftp.gnu.org/gnu/gcc/gcc-15.2.0.tar.xz

Configuration

To configure LibStdC++ from the the GNU Compiler Collection into our cross-compilation root, run the following command:

mkdir -v build && cd build
../libstdc++-v3/configure   \
    --host=$BRFS_TARGET     \
    --build=$BRFS_HOST      \
    --prefix=/usr           \
    --enable-multilib       \
    --disable-nls           \
    --disable-libstdcxx-pch \
    --with-gxx-include-dir=/tools/$BRFS_TARGET/include/c++/15.2.0

Stay in the build directory until this package is installed.

Compilation and Installation

To compile LibStdC++ from the GNU Compiler Collection, run the following command:

make

Next, to install LibStdC++ from the GNU Compiler Collection into the cross-tools tree, run the following command:

make DESTDIR=$BRFS install

Finally, remove the libtool archive files from the build root for libstdc++ and others since they can cause issues with other builds. To do so, run the following command:

rm -v $BRFS/usr/lib/lib{stdc++{,exp,fs},supc++}.la
rm -v $BRFS/usr/lib64/lib{stdc++{,exp,fs},supc++}.la

More details about this package is covered later in the core system build.
