Can we add a check on the libarchive version number when configuring pacman. You can run configure without a problem with a libarchive 1.x version but not actually complete the build. See http://bbs.archlinux.org/viewtopic.php?pid=367593
I know next to nothing about libarchive so I am giving this to someone else to take care of!
I doubt many ppl are still trying to build pacman with libarchive 1.x. Yeah, one did but well.. But in any cases, I am curious to know how to check version number at configure time. I don't know how to do it either. Though I believe I know one way to prevent the specific error that user was having. We could replace this stuff in configure.ac : # Check for libarchive AC_CHECK_LIB([archive], [archive_read_data], , AC_MSG_ERROR([libarchive is needed to compile pacman!])) by this : # Check for libarchive AC_CHECK_LIB([archive], [archive_read_open_filename], , AC_MSG_ERROR([libarchive is needed to compile pacman!])) What I don't know is when this read_open_filename function was introduced. And also what is the oldest libarchive version with which pacman is guaranteed to work.
