New submission from Jeroen Demeyer <jdeme...@cage.ugent.be>: The find_library_function() in Lib/distutils/unixccompiler.py does a very simple-minded check to determine the existence of a library. It basically only checks that a certain .so file exists. This may lead to false positives: the mere existence of a .so file does not imply that we can actually link against that library.
In addition to (or even better: instead of) checking the existence of the file, you should try to (in the spirit of autoconf) compile a simple program using $CC -l$LIB prog.c -o prog One particular instance of where things can go wrong is with a 32-bit/64-bit multilib installation. Python might find a 64-bit library in /usr/lib when we're actually compiling 32-bit with libraries in /usr/lib32. ---------- assignee: eric.araujo components: Distutils messages: 163968 nosy: eric.araujo, jdemeyer, tarek priority: normal severity: normal status: open title: find_library_file() should try to link type: compile error versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15182> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
