%general-entities; ]> Finally, clean up some extra files left around from running tests: rm -rf /tmp/* There are also several files installed in the /usr/lib and /usr/libexec directories with a file name extension of .la. These are "libtool archive" files. As already said, on a modern Linux system the libtool .la files are only useful for libltdl. No libraries in LFS are expected to be loaded by libltdl, and it's known that some .la files can cause BLFS packages fail to build. Remove those files now: find /usr/lib /usr/libexec -name \*.la -delete find /usr/lib32 -name \*.la -delete find /usr/libx32 -name \*.la -delete For more information about libtool archive files, see the BLFS section "About Libtool Archive (.la) files". The compiler built in and is still partially installed and not needed anymore. Remove it with: find /usr -depth -name $(uname -m)-lfs-linux-gnu\* | xargs rm -rf Finally, remove the temporary 'tester' user account created at the beginning of the previous chapter. userdel -r tester
