I haven't tried to build the current version, but I see it is in a tests subdirectory. People will know that I loathe static libs (specifically, I want to know which packages use a static lib from another package in case that other package ever has a known vulnerability). So I'm going to suggest that libpthread.a and libc.a might not be present ? In my own builds I keep libc.a available because it can be used all over the place in configure scripts and anyway if glibc has vulnerabilities it is time for a new system. For other static libs, like pthread, my post-install scripts rename them so that I can make them available if needed (tests are particularly likely to use static libs, for example the binutils gold tests need static libpthread.a). ĸen -- The right of the people to keep and arm Bears, shall not be infringed. -- http://lists.linuxfromscratch.org/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
