Hi all,
back in October [1] I asked for advice on building Winelib DLLs because I was unable to compile 64-bit DLLs on my openSUSE Tumbleweed machine. I've since opened bug 1231820 [2] on openSUSE's Bugzilla that has yet to be resolved (which I understand, given that developing Wine-only applications is pretty niche, I reckon).
While I can now (with Wine 10.0 from openSUSE's repositories) compile 32-bit Winelib DLLs without having to explicitly specify the library search path, 64-bit DLLs still don't work. This is because the packages are missing the relevant archive files (*.a) for 64-bit ELF; that is, all the libraries (*.so) are present in /usr/lib64/wine/x86_64-unix, but the corresponding *.a files are not.
I was trying to troubleshoot this earlier today but I'm now lost (since I cannot, for the life of me, reproduce the build process behaviour) and would be grateful for any discussion of what I might be misunderstanding/doing wrong or what might be going wrong with the packaging process.
The first noteworthy observation is that the RPM spec file [3, see lines 367-449] excludes all archive files when the package built is not the "-devel" variant, which is fine, but only includes the i386-unix archives when "-devel" is built. That is probably an oversight, but not the main problem, I reckon.
Namely: The x86_64-unix *.a files do not show up in the build logs [4] at all (Ctrl-F for "unix/libwinecrt0.a", for example). Even more, RPM itself complains that the files it should exclude are not found when building the non-devel variant of the package (Ctrl-F for "not found", messages around the 999s mark). This, to me, indicates that the files aren't even built.
As can be seen in the logs, openSUSE uses the following ./configure command line to build 64-bit Wine:
../configure --host=x86_64-suse-linux --build=x86_64-suse-linux --program-prefix= [...] --with-x --with-wayland --with-gstreamer --enable-win64 --verbose
(I've omitted prefix- and dir-related switches). I've built Wine from source with the following command line:
../configure [...] --build=x86_64-suse-linux --build=x86_64-suse-linux --enable-win64
(I've omitted --prefix only here). This produces an environment which can correctly build both 32-bit as well as 64-bit Winelib DLLs (without needing to set -L explicitly, as expected). I can see install-sh calls, as expected, for the *.a files in lib64/x86_64-unix, which are absent from the OBS build logs.
My commandline generates lib64/x86_64-unix and lib64/x86_64-windows.
On the other hand, the openSUSE build log for wine-devel-32bit [5] shows the i386-unix archive files being generated and installed. For 32-bit, they're using:
../configure --host=i586-suse-linux --build=i586-suse-linux --program-prefix= [...] --with-x --with-wayland --with-gstreamer --verbose
Since I don't expect --with-x --with-wayland --with-gstreamer --verbose to change anything on whether archive files are built, how come the 64-bit build on OBS is not providing these *.a for x86_64-unix?
I posted some more commandlines which don't seem to work correctly to the linked Bugzilla issue [2] back in December. I'm unsure if any of those I've tried there should be expected to produce correct results, so I'm focused on understanding of what's wrong with the 64-bit OBS build.
Thanks for any insight, advice, pointers, or corrections you might have for me.
Regards, Alexander Leithner
