Build Temporary Tools Part I

The commands are similar to the book for the packages in chapter 6. Slightly differences are mentioned in the former Temporary Tools Intro. More or less major differences are described below. If not otherwise stated the package will be compiled with make and installed with make install .

M4-1.4.19

Reference: 6.2. M4-1.4.19

./configure --prefix=/qlnx   \
            --host=$LFS_TGT \
            --build=$(build-aux/config.guess)
            --mandir=/qlnx/man \
            --infodir=/tmp

Ncurses-6.2

Reference: 6.3 Ncurses-6.2. The special build instructions for the tic program in the book can be ignored safely. It is ok here to use the one from the host. This is the modified configure command:

./configure --prefix=/qlnx \
            --host=$LFS_TGT \
            --build=$(./config.guess) \
            --includedir=/qlnx/inc \
            --datarootdir=/qlnx/dat \
            --mandir=/qlnx/man \
            --with-manpage-format=normal \
            --with-shared \
            --without-debug \
            --without-ada \
            --without-normal \
            --enable-widec

Compile and install the package:

$> make
$> make TIC_PATH=/usr/bin/tic install
$> echo "INPUT(-lncursesw)" > $LFS/qlnx/lib/libncurses.so

The above is correct. We use the tic from the host.

Bash-5.1.8

Reference: 6.4 Bash-5.1.8. The configure command is slightlyy modified to reflect the final locations:

./configure --prefix=/qlnx \
            --build=$(support/config.guess) \
            --host=$LFS_TGT \
            --without-bash-malloc \
            --includedir=/qlnx/inc \
            --datarootdir=/qlnx/dat \
            --mandir=/qlnx/man \
            --infodir=$LFS/tmp \
            --docdir=$LFS/tmp

Create symlinks¹⁾:

$> cd $LFS
$> mkdir $LFS/bin
$> ln -s bash bin/sh
$> ln -s bash /qlnx/bin/sh

The sh symlinks are required for the build inside the chroot environment. Delete the empty share directory:

rmdir /qlnx/share

Coreutils-8.32

Reference: 6.5 Coreutils-8.32. Ignore the last step moving chroot and the man pages. The configure command is slightly modified:

./configure --prefix=/qlnx \
            --host=$LFS_TGT \
            --build=$(build-aux/config.guess) \
            --enable-install-program=hostname \
            --enable-no-install-program=kill,uptime \
            --libexecdir=/qlnx/bin/libexec \
            --mandir=/qlnx/man \
            --infodir=$LFS/tmp

Diffutils-3.8

Reference: 6.6. Diffutils-3.8.

./configure --prefix=/qlnx \
            --host=$LFS_TGT \
            --mandir=/qlnx/man \
            --infodir=$LFS/tmp

File-5.40

Reference: 6.7 File-5.40. Ignore the first step to build the same magic file as at the host. Run the following command to install 'magic.mgc' directly in /qlnx/dat instead of /qlnx/dat/misc :

sed -i '/^pkgdatadir/s/\/misc//g' configure

Configure, compile and install the package:

./configure --prefix=/qlnx \
            --host=$LFS_TGT \
            --build=$(./config.guess) \
            --includedir=/qlnx/inc \
            --datarootdir=/qlnx/dat \
            --mandir=/qlnx/man

            --libexecdir=/qlnx/bin/libexec \

            --disable-static \
            --includedir=/qlnx/inc \
            --datarootdir=/qlnx/dat \
            --mandir=/qlnx/man \
            --docdir=$LFS/tmp

Binutils-2.37 - Pass 2

Reference: 6.17 Binutils-2.37 - Pass 2. Apply a patch to change the default library path to /qlnx/lib :

 patch -Np1 -i ../_sources/patches/binutils-default-lib.patch

This ensures that the crt*.o files will be found by the linker (ld).

../configure --prefix=/qlnx \
             --build=$(../config.guess) \
             --host=$LFS_TGT \
             --disable-nls \
             --enable-shared \
             --disable-werror \
             --enable-64-bit-bfd \
             --includedir=/qlnx/inc \
             --datarootdir=/qlnx/dat \
             --mandir=/qlnx/man \
             --infodir=$LFS/tmp

In qLinux the target triplet is in /qlnx/lib/binutils . This have to be fixed in the new created build/Makefile :

sed -i '/^tooldir/s/}\/x86_/}\/lib\/binutils\/x86_/g' Makefile
sed -i '/^build_tooldir/s/}\/x86_/}\/lib\/binutils\/x86_/g' Makefile

Compile and install the package:

$> make
$> make install -j1

The workaround from the book to install libctf.so was not required. The book says to do the following command:

$> install -vm755 libctf/.libs/libctf.so.0.0.0 [$LFS]/qlnx/lib

Against the above command does link the libctf with an invalid path to other libraries. To verify that it is linked correct do

ldd /qlnx/lib/libcft.so*

Everything have to be linked to libraries in /qlnx/lib/* .

GCC-11.2.0 - Pass 2

Reference: 6.18. GCC-11.2.0 - Pass 2.

Important: Start with a fresh extracted sources from the tarball always!

Extract the mpfr, mpc and gmp packages into the source tree. Replace the lib64 (patch ):

patch -Np0 -i ../_sources/_patches/0001-pure64-for-x86-64.patch

The book suggests a sed command for this, but the patch is more strict.

Change the default (native) include directory (patch ) to /qlnx/inc , the location of the dynamic loader and the startfile prefix:

patch -Np1 -i ../_sources/_patches/config-gcc-qlinux.patch

On some systems the compilation could fail with an error saying that fenv.h (and many other headers) was not found. In this case apply the following patch as a workaround:

patch -Np1 -i ../_sources/patches/gcc-nostinc++.patch

Start over an interrupted build of gcc from fresh extracted sources.

Enable posix threads support in libgcc:

mkdir -pv $LFS_TGT/libgcc
ln -s ../../../libgcc/gthr-posix.h $LFS_TGT/libgcc/gthr-default.h

In the build directory configure the package:

../configure --prefix=/qlnx \
             --build=$(../config.guess) \
             --host=$LFS_TGT \
             CC_FOR_TARGET=$LFS_TGT-gcc \
             CXX_FOR_TARGET=$LFS_TGT-g++ \
             --with-tune=generic \
             --with-arch=x86-64 \
             --enable-languages=c,c++ \
             --disable-bootstrap \
             --enable-initfini-array \
             --disable-multilib \
             --disable-libsanitizer \
             --disable-werror \
             --libexecdir=/qlnx/bin/libexec \
             --includedir=/qlnx/inc \
             --datarootdir=/qlnx/dat \
             --mandir=/qlnx/man \
             --infodir=$LFS/tmp

The build steps are different from the book, instead it's done the “mussel way”. First the gcc itself:

make all-gcc

Before continue check that the dynamic loader is correct:

readelf -l gcc/cc1 | grep ld

Install it:

make install-gcc

Build an install libgcc make -C $LFS_TGT/libgcc distclean make enable-shared=yes all-target-libgcc make install-target-libgcc </code>

Build libstdc++-v3 for c++ support:

make all-target-libstdc++-v3
make install-target-libstdc++-v3

Optional build OpenMP support (libgomp):

make all-target-libgomp
make install-target-libgomp

Verify that all works like expected:

gcc dummy.c

Check for the correct dynamic loader.

readelf -l a.out | grep ld

Execute the a.out file:

./a.out

There should be no output as well no error. Do the same for c++. First create a c++ testfile:

cat > dummy.cpp << "EOF"
#include<iostream>
int main(int argc, char** argv) {
  using namespace std;
  int ret = 0;
  return ret;
}
EOF

Compile it:

g++ dummy.cpp -o cpp.out

and repeat the last to steps with cpp.out file like with a.out from above.
