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 \
--without-headers --with-newlib --disable-decimal-float \
--disable-libgomp --disable-libmudflap --disable-libssp \
--with-mpfr=${CLFS}/cross-tools --with-gmp=${CLFS}/cross-tools \
--with-ppl=${CLFS}/cross-tools --with-cloog=${CLFS}/cross-tools \
--disable-shared --disable-threads --enable-languages=c
The meaning of the configure options:
--disable-shared
Disables the creation of the shared libraries.
--disable-threads
This will prevent GCC from looking for the multi-thread include files, since they haven't been created for this architecture yet. GCC will be able to find the multi-thread information after the EGLIBC headers are created.
--enable-languages=c
This option ensures that only the C compiler is built.
