%general-entities; ]> Bash temporary system When Bash 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 ./configure --prefix=/tools \ --build=${CLFS_HOST} --host=${CLFS_TARGET} \ --without-bash-malloc --cache-file=config.cache --without-bash-malloc This option turns off the use of Bash's memory allocation (malloc) function which is known to cause segmentation faults. By turning this option off, Bash will use the malloc functions from Glibc which are more stable. make install Make a link for programs that use sh for a shell: ln -sv bash /tools/bin/sh
