There are multiple versions of this library, one in /usr/lib (with a .la file), and one elsewhere, without a .la file. I need the one elsewhere, because I'm crosscompiling. I know I should probably try what happens when both have a .la file, but the second one was not built with libtool, it's a stripped down version for an embedded target.

OK, now I've given the library in -Ldir a .la file as well. Now both libraries have a .la file, and libtool-1.5.2 uses the correct library, in -Ldir. So that's solved then. I don't want to go back to 1.4.3 to try whether that also would have worked with both .la files in place. Thanks for the help guys.

So that's solved then. So, basically, it sounds like libtool has reinvented the very annoying Tru64 library search mechanism, where any shared libraries are found before static libraries regardless of the relative order on the library path, except as applied to *.la files. This sounds like a bug to me. The Tru64 behavior causes no end of surprises and means that you can't easily link with (often newer) locally installed static libraries if the operating system happens to come with some dynamic library by the same name. What was the reason for this change, or was it accidental? -- Russ Allbery ([EMAIL PROTECTED]) http://www.eyrie.org/~eagle/ ___ Libtool mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/libtool

I don't think libtool is doing this. It looks like it's preferring libraries with corresponding .la files. Even that is a bug though.

This bug has been reported before since it was discussed on this list a month ago. It appears to be a known problem.

libtool-1.5.2 searches /usr/lib before -Ldir
I've downloaded and installed libtool-1.5.2, and tried the same as with my reports about 1.4.3 It behaves exactly the same, it finds libraries in /usr/lib, instead of where -L wants them to be found. Then I replaced newlib_search_path=something else here $newlib_search_path by newlib_search_path=$newlib_search_path something else here everywhere in ltmain.in, one by one, but that did not make a difference. Then I took another look at the --debug output of the libtool script, and it occurred to me that libtool is actually looking for an .la script. When it does not find the .la script, it passes the original -lxyz parameter to gcc, instead of trying to replace it by the library it thinks should be used. gcc knows how to use -Ldir, and links against the correct library. So I removed the .la script belonging to my library in /usr/lib, libtool does not find it anymore, and now it works. But I guess that's not the preferred way to handle this...
