Hi,
In this chapter we are going to compile and install GCC package again, this is the second pass of the package.
Note :
- Please check the version of the package when you compile and install, at the time of writing the package was at version 10.2.0
- You should be logged in as lfs user, when you perform the actions described here.
- Change directory to the sources folder (/mnt/lfs/sources)
- Please check http://linuxfromscratch.org/lfs/view/stable/chapter06/gcc-pass2.html for more details.
Remove the directory gcc-10.2.0 if it's still exist in sources directory.
$ rm -rf gcc-10.2.0
Unpack the package tarball and change directory.
$ tar -xvf gcc-10.2.0.tar.xz
$ cd gcc-10.2.0
Unpack the packages and move it to the gcc-10.2.0 directory.
$ tar -xf ../mpfr-4.1.0.tar.xz
$ mv -v mpfr-4.1.0 mpfr
$ tar -xf ../gmp-6.2.0.tar.xz
$ mv -v gmp-6.2.0 gmp
$ tar -xf ../mpc-1.1.0.tar.gz
$ mv -v mpc-1.1.0 mpc
If building on x86_64, change the default directory name for 64-bit libraries to “lib”
$ case $(uname -m) in
x86_64)
sed -e '/m64=/s/lib64/lib/' -i.orig gcc/config/i386/t-linux64
;;
esac
Create the build directory and move into it.
$ mkdir -v build
$ cd build
Create a symlink that allows libgcc to be built with posix threads support
$ mkdir -pv $LFS_TGT/libgcc
$ ln -s ../../../libgcc/gthr-posix.h $LFS_TGT/libgcc/gthr-default.h
Preparing Gcc package for compilation.
../configure \
--build=$(../config.guess) \
--host=$LFS_TGT \
--prefix=/usr \
CC_FOR_TARGET=$LFS_TGT-gcc \
--with-build-sysroot=$LFS \
--enable-initfini-array \
--disable-nls \
--disable-multilib \
--disable-decimal-float \
--disable-libatomic \
--disable-libgomp \
--disable-libquadmath \
--disable-libssp \
--disable-libvtv \
--disable-libstdcxx \
--enable-languages=c,c++
Compiling the package
$ make -j4
Installing the package
$ make DESTDIR=$LFS install
Creating a utility symlink.
$ ln -sv gcc $LFS/usr/bin/cc
