Details on this package are located in Section 6.12.2, “Contents of GCC.”
The GCC package contains the GNU compiler collection, which includes the C and C++ compilers.
To make sure that a couple of tools use the proper syntax, apply the following patch:
patch -Np1 -i ../gcc-4.1.1-posix-1.patch
The following patch is needed for GCC to build against uClibc:
patch -Np1 -i ../gcc-4.1.1-uclibc-1.patch
The following patch fixes the searching of multilib dirs for specs file.The patch standardizes the gcc drivers path iteration functions, ensuring multilib directories are searched in the correct order. This fixes various issues, most noticably with libtool on multilib systems:
patch -Np1 -i ../gcc-4.1.1-PR20425-1.patch
The following patch ensures that gcc does not search the /usr directory for libgcc_s.so when cross-compiling:
patch -Np1 -i ../gcc-4.1.1-cross_search_paths-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:
../gcc-4.1.1/configure --prefix=${CLFS}/cross-tools \
--host=${CLFS_HOST} --target=${CLFS_TARGET} --disable-multilib \
--with-sysroot=${CLFS} --disable-nls --disable-shared --disable-threads \
--enable-languages=c
The meaning of the configure options:
Disables the creation of the shared libraries.
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 Glibc headers are created.
This option ensures that only the C compiler is built.
Continue with compiling the package:
make all-gcc
Install the package:
make install-gcc
