6.28.1. Environment Settings
This package requires compiler variables to be set for the target
in the environment.
export CC="${CLFS_TARGET}-gcc"
export CXX="${CLFS_TARGET}-g++"
export AR="${CLFS_TARGET}-ar"
export AS="${CLFS_TARGET}-as"
export RANLIB="${CLFS_TARGET}-ranlib"
export LD="${CLFS_TARGET}-ld"
export STRIP="${CLFS_TARGET}-strip"
6.28.2. Installation of Bash
The following patch contains updates from the maintainer. The
maintainer of Bash only releases these patches to fix serious
issues:
patch -Np1 -i ../bash-4.0-branch_update-6.patch
When bBsh is cross-compiled, it cannot test for the presence of
named pipes, among other things. If you used su to become an unprivileged
user, this combination will cause Bash to build without
process substitution, which
will break one of the C++ test scripts in eglibc
. The following prevents future problems by
skipping the check for named pipes, as well as other tests that can
not run while cross-compiling or that do not run properly:
cat > config.cache << "EOF"
ac_cv_func_mmap_fixed_mapped=yes
ac_cv_func_strcoll_works=yes
ac_cv_func_working_mktime=yes
bash_cv_func_sigsetjmp=present
bash_cv_getcwd_malloc=yes
bash_cv_job_control_missing=present
bash_cv_printf_a_format=yes
bash_cv_sys_named_pipes=present
bash_cv_ulimit_maxfds=yes
bash_cv_under_sys_siglist=yes
bash_cv_unusable_rtsigs=no
gt_cv_int_divbyzero_sigfpe=yes
EOF
Prepare Bash for compilation:
./configure --build=${CLFS_HOST} --host=${CLFS_TARGET} \
--prefix=/usr --bindir=/bin --cache-file=config.cache \
--without-bash-malloc --with-installed-readline
The meaning of the configure option:
-
--with-installed-readline
-
This option tells Bash to use the readline
library that is already installed
on the system rather than using its own readline version.
Compile the package:
make
Install the package:
make DESTDIR=${CLFS} htmldir=/usr/share/doc/bash-4.0 install
Create /bin/sh:
ln -sfv bash ${CLFS}/bin/sh
