This is suprising. I thought this was one of the benefits of libtool
-- portable library dependencies.
It depends on which version of libtool you're using. IIRC, libtool
1.3.5 (the latest release) still doesn't fully support inter-library
dependencies. 1.4-to-be (CVS trunk) is supposed to fix this problem.

Murray Cumming wrote: I'm trying to use automake/autoconf to build a shared library whose source code is neatly organised sub directories (about 5 levels wide and 5 levels deep). If this was an application then I would build static libraries in each of the subfolders and link them all together at the top. But when I do something like this: libfoo_la_LDADD = exceptions/libexceptions.la factories/libfactories.la libtool complains that the .la libraries are not libtool objects. I could build libtool libraries in the sub directories instead of static libraries, ? but then I'd have to install each of those temporary libraries. That would be stupid. So, how should I use automake to build a shared library if the source is in sub directories? Paul Berrevoets [EMAIL PROTECTED] wrote: You create what are called 'convenience' libraries in libtool. In exceptions/Makefile.am: noinst_LTLIBRARIES = libexceptions.la ... Convenience libraries are not installed, and the object they contain will be included in the higher level ltlibrary that LDADD's them. I've got that working now. But here's a couple of important details for the record: 1) This doesn't work recursively. For instance, if sub contains, subsub, which contains subsusbsub, then the library at sub will contain subsub but not subsubsub. Therefore you have to LIBADD all the libraries in the top makefile. 2) noinst libraries with the same names in different directories will conflict, leading to multiple definitions of one of them. So you should probably name each noinst library according to its complete path. e.g. libsub_subsub_subsubsub.la. Is there any news on a timeline for the prophesied version of automake that properly handles sources in sub directories?

I didn't do it before because the automake manual explicitly states that noinst_LTLIBRARIES is not allowed. I guess that's wrong.

Re: [Re: Shared library with source in sub directories]
Murray Apparently I should do with this with a noinst_LTLIBRARIES, so Murray you do need to correct the bit in the automake manual that Murray says that it isn't allowed. I think that has already been fixed. When I looked at my copy of the manual this morning it said that check_LTLIBRARIES is disallowed, but noinst_ is used for convenience libraries. Tom
