Details on this package are located in Section 6.11.3, “Contents of GCC.”
The GCC package contains the GNU compiler collection, which includes the C and C++ compilers.
The following patch contains a number of updates to the 4.4.1 branch by the GCC developers:
patch -Np1 -i ../gcc-4.4.1-branch_update-1.patch
The GCC documentation recommends building GCC outside of the source directory in a dedicated build directory:
mkdir -v ../gcc-build cd ../gcc-build
Prepare GCC for compilation:
AR=ar LDFLAGS="-Wl,-rpath,${CLFS}/cross-tools/lib" \
../gcc-4.4.1/configure --prefix=${CLFS}/cross-tools \
--build=${CLFS_HOST} --host=${CLFS_HOST} --target=${CLFS_TARGET} \
--disable-multilib --with-sysroot=${CLFS} --disable-nls \
--enable-shared --enable-languages=c,c++ --enable-__cxa_atexit \
--with-mpfr=${CLFS}/cross-tools --with-gmp=${CLFS}/cross-tools \
--with-ppl=${CLFS}/cross-tools --with-cloog=${CLFS}/cross-tools \
--enable-c99 --enable-long-long --enable-threads=posix
The meaning of the new configure options:
--enable-languages=c,c++
This option ensures that only the C and C++ compilers are built.
--enable-__cxa_atexit
This option allows use of __cxa_atexit, rather than atexit, to register C++ destructors for local statics and global objects and is essential for fully standards-compliant handling of destructors. It also affects the C++ ABI and therefore results in C++ shared libraries and C++ programs that are interoperable with other Linux distributions.
--enable-c99
Enable C99 support for C programs.
--enable-long-long
Enables long long support in the compiler.
--enable-threads=posix
This enables C++ exception handling for multi-threaded code.
Continue with compiling the package:
make AS_FOR_TARGET="${CLFS_TARGET}-as" \
LD_FOR_TARGET="${CLFS_TARGET}-ld"
Install the package:
make install
