&buildtime; &grep-time-tools; &diskspace; &grep-compsize-tools; &aa-grep-down; &aa-grep-dep;   Prepare Grep for compilation: ./configure --prefix=/tools \     --disable-perl-regexp --with-included-regex The meaning of the configure options: --disable-perl-regexp: This makes sure that grep does not get linked against a PCRE library that may be present on the host and would not be available once we enter the chroot environment. --with-included-regex: This ensures that Grep uses its internal regular expression code. Without this switch, Grep will use the code from Glibc, which is known to be slightly buggy. Compile the programs: make (If you insist on testing the results, then issue: make check.) Then install them and their documentation: make install   The details on this package are found in .
