Removing duplicate occurences from dependency_libs
Hi, somewhere between libtool 1.3.x and 1.4, you did the following: 1999-12-15 Thomas Tanner <[EMAIL PROTECTED]> * ltmain.in: don't remove multiple occurences from dependency_libs of a library, otherwise many dependencies would get lost If you have a "complicated" dependency setup, this will slow down linking in a very extreme way (it is more than 5 times slower for me) because I get libraries like -lm or -ldl listed over 30 times in the dependency_libs. Is it possible to add an argument to libtool to get back the old behavior, for instance -unique-dependency-libs ? Here's a patch for this: diff -- Martin Baulig [EMAIL PROTECTED] (private) [EMAIL PROTECTED] (work)

This does not work. Imagine the following scenario: liba.la - depends on -lm libb.la - depends on -lm libc.la - depends on -la and -lb You'll get -l twice in libc.la. -- Martin Baulig [EMAIL PROTECTED] (private) [EMAIL PROTECTED] (work) ___ Libtool mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/libtool

Well, that's what didn't work for me. I'll debug it later on. -- Martin Baulig [EMAIL PROTECTED] (private) [EMAIL PROTECTED] (work) ___ Libtool mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/libtool
