I have installed all the latest mingw autoconf/libtool stuff. As far as I understand it, apr-util uses the libtool created by apr. It says: $ /C/Development/svn-1.6.3/build-1/libtool --help ... host-triplet: i686-pc-mingw32 shell: /bin/sh compiler: gcc compiler flags: linker: c:/mingw-4.4.0/mingw32/bin/ld.exe (gnu? yes) libtool: (GNU libtool 1.3110 2009-07-01) 2.2.7a automake: automake (GNU automake) 1.11 autoconf: autoconf (GNU Autoconf) 2.63 I have edited it a bit, so it creates dlls: # Flag that allows shared libraries with undefined symbols to be built. #allow_undefined_flag="unsupported" allow_undefined_flag="yes" # Flag that enforces no undefined symbols. no_undefined_flag="--no-undefined" and I also had to use cd c:/mingw-4.4.0/share/aclocal cat lt~obsolete.m4 ltoptions.m4 ltsugar.m4 ltversion.m4 >> libtool.m4 to make apr-utils configure script work (it failed with lt_decl_varnames errors before). >> With a few tweaks to libtool (--no-undefined) it builds the shared >> libraries for both.

After creating a dll.a by hand dlltool.exe -z test.def --export-all-symbols libaprutil-1-0.dll dlltool.exe -d test.def -l libaprutil-1.dll.a (plus removing a few symbols from the def file) it links but then complains at runtime about missing symbols. Interesting is that if I use depend.exe (Dependency Walker) it says there are a lot of referenced symbols but no symbol except one is actually available in libaprutil-1-0.dll. That single available symbol is also the only symbol listed in the dll.a file created when running make. So it looks like the problem is not the creation of the dll.a but of the dll itself... Does this make sense? > Cheers, > Ralf Thanks for trying to help me :) -- Martin |
