Thanks for using it, :) BTW: Perhaps you remember, I once contacted you because of some problems with C++ and static objects in shared libs. I found out (or read in a news group), that most compilers on such plattforms do some magic before calling the linker. So, what libtool have to do to support such plattforms (Solaris, FreeBSD and perhaps some more), is to call the compiler and not the linker to create C++ shared libs. CC (under Solaris) has the same options then the linker, but should create correct libraries. Currently I set CC to CXX before I run AM_PROG_LIBTOOL to let libtool find the correct linker options for the C++ compiler instead of the C compiler. I just wanted to let you know, what I found out. I thought about patching libtool to have better support for C++, but this would mean some drastic changes, so I left it up to you ;) Greets, Stephan -- Stephan Kulow (coolo@kde.org) Student of medical CS Medical University of Luebeck GCS/M/MD d-x s++: a-- C+++$ ULS+++ P--- L++ E W- N- o?

Everything works good except if I'm trying to use C++ templates in my code and put this in a shared library. The linker is afterwards always complaining about missing references. The problem occurs because libtool renames the object files from xxx.o to xxx.lo. The SUN C++ compiler builds for himself a Template.DB and this somehow doens't match anymore with the object file. Have you ever heard of this problem and do you eventually allready have a solution? I search in Deja News but couldn't find anything. A solution I could think of would be to rename the xxx.lo file back to xxx.o before the linking phase.

When I looked into it, I found that the nm command used to create the export list doesn't pass a -C flag. On AIX, the -C flag says to leave C++ names mangled. Since the function names weren't mangled, the sed line didn't recognize them as functions, so they weren't put into the .exp file. I found that I could fix the problem by adding a -C flag to ac_cv_path_NM in config.guess. I suppose the configure script should check for that and do it automatically. I'm running libtool version 1.2 on an AIX 4.2 box (powerpc-ibm-aix4.2.1.0). I have some test files that I can give to anyone who wants to test this. And I can test potential fixes on my machine.
