Temporary Tools Part II

Entering the Chroot'ed Environment

Enter the Chroot ( sudo ~/dochroot ). If not done already, the first thing we have to do is to create  /bin/sh  for compatibility reasons:

$> mkdir /bin
$> cd /bin
$> ln -s ../qlnx/bin/sh

This is really temporarily to build the rest of qLinux. Later on we will get rid of "/bin/sh" - fortunately we running a linux kernel. Some more directories and files:

$> mkdir /tmp && chmod 1777 /tmp
$> mkdir -p /home/admin

Building Additional Temporary Tools

Some packages from the chapter 7 of the book can be skipped, because they are not required. The ones are:

Thus the following packages remains:

        Libstdc++ from GCC-11.2.0, Pass 2
        Bison-3.7.6
        Util-linux-2.37.2

Libstdc++ from GCC-11.2.0, Pass 2

Reference: Libstdc++ from GCC-11.2.0, Pass 2. This is done already.

Bison-3.7.6

Reference: 7.9. Bison-3.7.6.

./configure --prefix=/qlnx \
            --docdir=/tmp \
            --mandir=/qlnx/man \
            --datarootdir=/qlnx/dat \
            --infodir=/tmp

Fix the shebang of  yacc :

sed -i 's/^#\!*.\/bin\/sh/#\!\/qlnx\/bin\/sh/g' /qlnx/bin/yacc

Util-linux-2.37.2

Reference: 7.13. Util-linux-2.37.2.

Apply a patch to adjust path names for qLinux:

./configure --prefix=/qlnx \
            --bindir=/qlnx/bin \
            --sysconfdir=/qlnx/etc \
            --includedir=/qlnx/inc \
            --mandir=/qlnx/man \
            --datarootdir=/qlnx/dat \
            --docdir=/tmp \
            --infodir=/tmp

This package doesn't have any scripts with a shebang, but actually some man pages have a wrong path (and even others like “/etc/passwd” or “/proc/mounts” etc.). The configure option  –sbindir  doesn't work for all programs, so some will be installed in  {$prefix]/sbin  anyway. Thus we don't use this option and move the admin executables with modified rights after install:

chmod 0754 qlnx/sbin/*
mv /qlnx/sbin/* /qlnx/bin
rmdir /qlnx/sbin
