Package: grep Version: 2.5.3~dfsg-5 Tags: patch User: [EMAIL PROTECTED] Usertags: ubuntu-patch origin-ubuntu intrepid
Hi, When building the current grep package on glibc 2.8, the configure check for glibc's regex will get confused since it does not define _GNU_SOURCE. As a result, it builds the package with the internal copy of the regex library, which seems to be seriously broken (e. g. grep -i does not work any more, see https://launchpad.net/bugs/241990). I worked around this by explicitly configuring with --without-included-regex. Upstream should fix their configure test to define _GNU_SOURCE (and maybe also their internal regex lib), but as a distribution the configure argument suffices for now. Please note that this does not directly affect sid/lenny ATM, since we are frozen with glibc 2.7. However, it is a future trap which we should avoid altogether in Debian, so please feel free to apply it right now.
