Any libtool developer interested in teaming up to add AIX 5.x support to libtool? I have a handful of settings that I tweeked by hand to get things working right. I can just describe what settings are ultimately needed, or try to hack the changes into scripts and send the diffs. what did you find that you had to change? First I've been doing Linux/Solaris stuff for years. AIX is new to me and I'm trying to port a multi-language code with a large test-suite. The code builds static and dynamically loadable objects and tests both. The latter case really is dlopen(), not just shared libraries. AIX is less being less than cooperative. Libtool is currently builds shared objects only and dumps them into *.a files. This is a problem for me since I've got #ifdef PIC preprocessor directives in the code. Static and dynamic loaded libraries do different things and shouldn't be mixed in my case. I'm using the -G option to create dynamic libraries (similar I think, to -fPIC for gcc). I think its new to AIX5, and supercedes the -bM:SRE etc etc. stuff (not sure). I also add the -qstaticinline command for C++ code to suppress warnings about duplicate symbols. (Which brings up another question: when is libtool gonna support C++?) I can manually build separate static (*.a) and dynamic (*.so) libraries. When linking static I used -bstatic. When linking dynamic I used -bdynamic -brtl. (Note: -brtl is necessary for linkage editor to include *.so files in its search. Otherwise it only inspects *.a files!?!) I think that's about it. Oh and since -DPIC doesn't work for my preprocessed fortran (-D means something else for xlF), I use -WF,-DPIC. I'd be willing to work with someone to refine the code if I'm the only one with access to an AIX 5.x box. You're not. But I'm perplexed since I've been using libtool and autoconf on AIX 5L for some time. Part of the problem was indeed a screwup on our end. Some of the files we were using (e.g. config.guess) wasn't being updated and got out of synch. (We've been using autoconf/automake/libtool for almost three years now.) Part of the problem is that AIX is just wierd... or at least different enough from Linux/Solaris/OSF to be annoying. From what I've learned from our local compiler guru, everything that libtool does is probably correct for older versions of AIX. My sense is that in version 5, IBM is taking another step twords doing things more akin to other Unices... (at least with the right flags). Autotools are sophisticated enough that they should take advantage of that. ... at least that's what I'm wanting/hoping. Maybe someone knows a reason why I can't simultaneously have static *.a and dynamically loadable *.so on AIX... just like I do for Linux/Solaris? If so, I'd like to understand why.

If so, I'd like to understand why. AIX traditionally uses a completely different library format than other systems. Both the shared and the static objects are supposed to go into the same .a file, and the linker will chose whichever is appropriate. This means that .a files on an AIX system may be used at runtime and may actually be shared libraries. I don't know how much of that, if any, AIX 5.x changed. -- Russ Allbery ([EMAIL PROTECTED]) http://www.eyrie.org/~eagle/ ___ Libtool mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/libtool

Over the last 2.5 years we've been using Autotools, it seems we've stepped up to new versions without upgrading all the ancillary files (like config.guess).
