Adding mingw package for libuuid-devel (with pkg-config file uuid.pc)
by Sim Tov 17 Jun '21

17 Jun '21

Hello, I try to create a CI/CD pipeline that would allow to automatically cross-compile gImageReader's GTK interface for Windows. Here is the Dockerfile in my fork: https://github.com/AvtechScientific/gImageReader/blob/master/packaging/win3… . To build it, one needs to run: `sudo docker build -t gimagereader_buildenv packaging/win32`, to build GTK UI run `sudo docker run -v $PWD:/workspace gimagereader_buildenv packaging/win32/makeinstaller.sh x86_64 gtk`. I was able to make some progress but now I'm stuck with `uuid`. Here is CMake's error: Checking for module 'uuid' -- No package 'uuid' found. Full error output: https://paste.debian.net/1201327/ If I run `find / -name "*uuid*"` inside of the container it looks like uuid is there and here is what I get: https://paste.debian.net/1201326/ . 1. Does the existence of these files imply that libuuid-devel was actually added to MinGW, just not as a separate package? /usr/x86_64-w64-mingw32/sys-root/mingw/lib/libuuid.a /usr/x86_64-w64-mingw32/sys-root/mingw/include/uuids.h 2. In order to overcome this issue I tried to look on the Fedora's native uuid.pc and adopt it inside of the container: nano /usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig/uuid.pc prefix=/usr/x86_64-w64-mingw32/sys-root/mingw exec_prefix=/usr/x86_64-w64-mingw32/sys-root/mingw libdir=/usr/x86_64-w64-mingw32/sys-root/mingw/lib includedir=/usr/x86_64-w64-mingw32/sys-root/mingw/include Name: uuid Description: Universally unique id library Version: 2.37.0 Requires: Cflags: -I${includedir}/ Libs: -L${libdir} -luuid I'm not sure it is correct, but CMake accepted it so far... Does this file looks OK to you? 3. May I ask you to add a separate mingw package for libuuid-devel (with pkg-config file uuid.pc)? Thank you in advance!

Getting useful gdb output
by Richard Shaw 24 Mar '21

24 Mar '21

I'm working on building a Win 64 bit version of a package I maintain to help upstream. Currently only 32-bit windows installers are produced because the 64-bit ones segfault on start up. Trying to get a useful debug environment on Windows has been a chore, but I have MinGW w64 installed including gdb, however, I can't see anything useful in the output. What else do I need to do to get useful output for troubleshooting Win64 specific MinGW issues?

Dan already noted that you can run the cross-compiler on any architecture. However it is a good question about why the final packages are "noarch". Windows these days only exists on i686, x86-64 and aarch64. I don't know what mingw-w64's support for aarch64 is like, but we only bother building i686 ("mingw32-*") and x86-64 ("mingw64-*") packages. Normally the end result is intended to be run on Windows, so it's "noarch" as far as Fedora is concerned. The normal deployment method is to use NSIS to generate an installer (from files in the RPMs you've installed locally) which is copied over to Windows. You can do this on any arch. But you can also run the code under Wine on an x86-64 host. Probably on i686 host but I doubt anyone has done that in a long while. Wine doesn't work on non-x86 arches. I don't think that Koji / RPM is really designed to cope with all this subtlety though. And implementing it just for mingw is way too much work. > Fullarch Linux packages are built on various architectures. Is MinGW > toolchain available on all of them?

Yes, any build arch can be used. We don't usually run tests in %check because running Wine under Koji is a pain. It requires a specifically configured $HOME, and X server (even for console programs).

Merging mingw specs into native spec
by Daniel P. Berrangé 02 Mar '21

02 Mar '21

Way back when we first started the mingw project in Fedora we took the decision to maintain the mingw builds as separate source RPMs in Fedora. The rationale was that mingw support was a new concept to Fedora with many unknowns. We often had custom mingw only patches, and there was a decent chance there would be breakage upon rebases. We didn't want to burden the native package maintainers with mingw support as that would have increased pushback against the effort. This decision was always going to cause us problems with keeping the mingw dist-git packages in sync with native dist-git packages. This is especially important when it comes to security fixes, and there have been reasonably well justified complaints about mingw lagging native wrt to CVE fixing in recent times. Since the early days we merged the separate mingw32-$PKG / mingw64-$PKG source RPMS into a single mingw-$PKG in dist-git. The need for patching mingw RPMs to fix problems in Fedora doesn't seem any higher than the need for patching to fix native build problem. Generally things just work when rebasing, because most upstreams recognize the importance of keeping their projects working on mingw. IOW, we were afraid of a maintainer burden that has turned out to largely not exist. To address this non-existant burden, we intentionally made the maint of mingw packages harder than it needs to be in Fedora. This is a long winded way of saying I think it is time to update the mingw packaging guidelines to allow for, even recommend, mingw packaging to be a standard part of the native RPM spec. In doing so we eliminate the main burden of mingw packaging in Feora and guarantee that we'll always be up to date wrt bug/security fixes and rebases. I've done some basic tests with libvirt-glib upstream which recently changed to using Meson. Supporting mingw in the main libvirt-glib.spec was largely trivial. I simply needed to copy the various blocks of the mingw-libvirt-glib.spec file into the libvirt-glib.spec, ending up with a diff: diff --git a/libvirt-glib.spec.in b/libvirt-glib.spec.in index

logic that sets these doesn't work: %mingw32_pkg_name %(echo %{name} | sed 's/^mingw-/mingw32-/') Presumably we can fix that macro so that it does the right thing when no mingw- prefix exists in the first place * We can't use %mingw_package_header because that splatters the native debuginfo generation. So we must explicitly add mingw debuginfo packages by referencing %{?mingw_debug_package} and at end of %install add %mingw_debug_install_post * %mingw_package_header has reference to overriding strip/objdump to prevent corruption of binaries. We can't do that override because we need native strip/objdump for the native builds. AFAICT though, no corruption happened to my DLLs even without this strip/objdump override. Looks like this caveat might be obsolete, unless the scenarios it hits are more niche than I tested. * %mingw_package_header tries to disable the internal dependancy generator on RHEL 6. For reasons I don't understand, it ends up disabling it on Fedora too. %mingw_package_header \ %global __strip %{mingw_strip} \ %global __objdump %{mingw_objdump} \ %if 0%{?rhel} == 6 \ %global _use_internal_dependency_generator 0 \ %global __find_requires %{mingw_findrequires} \ %global __find_provides %{mingw_findprovides} \ %endif \ %global __debug_install_post %%{mingw_debug_install_post} \ %{nil} Those three %global inside the rhel conditional *do* get evaluated on Fedora. We can see this in the old build logs in fact https://kojipkgs.fedoraproject.org/packages/mingw-libvirt-glib/4.0.0/1.fc35… warning: Deprecated external dependency generator is used! Finding Provides: /usr/lib/rpm/mingw-find-provides.sh mingw32 mingw64 .... When I hack macros.mingw to remove the dep generator override code entirely, almost everything still seems to work. rpm's built-in dep generator still adds the mingw32(libssp-0.dll) virtual deps. The only thing that gets lost is the dep on mingw-pkg-config IOW it looks like RPMs built-in dep generator pretty much does the right thing. Just need to add a manual mingw-pkg-config dep * Converting meson packages was easy because meson always uses a separate build dir. Many autoconf based packages default to building in the source dir. The first step would thus have to be to make the native build use a separate build dir. In theory this should be easy as mingw autoconf macros are already doing this, but I always expect dragons with autoconf. In summary based on my tests I think killing off the separate dist-git / RPM spec for mingw looks feasible unless someone knows of hidden show stoppers I haven't hit yet. I think we should go ahead and do this for some packages to demonstrate the concept in the real world, and I'm volunteering to coordinate it for all the virtualization packages I'm involved in maint of because I can't even reliably keep them in sync myself. libvirt, libvirt-glib, libosinfo, osinfo-db-tools, gtk-vnc, spice-gtk all use meson, so should mirror the approach above and be quite easy. Once we can demonstrate the real world impact, we can socialize the idea on Fedora devel list more widely and then also approach maintainers of other native packages to attempt to convince them to accept mingw sub-RPMs into their specs. Every mingw package we can get merged into native package frees up a little more time for to spend on the remaining mingw packages that are still separate. Ideally we'd get 100% merged long term, but even if we get refusals from native maintainers, we'll still be better off with those we do succeed in merging.

How to override CMAKE_FIND_ROOT_PATH
by Richard Shaw 13 Aug '20

13 Aug '20

I have a CMake project where I'm building wxWidgets on the fly. The libraries are in a subdirectory of the build directory. Unfortunately the CMAKE_FIND_ROOT_PATH gets prepended to the library name even though it's being provided as an absolute directory rather than a relative one. From running cmake --debug-find: find_library considered the following locations: /usr/x86_64-w64-mingw32/sys-root/mingw/home/build/build/freedv/external/dist/lib/(lib|)wxregexu-3.1-x86_64-w64-mingw32(\.dll|\.dll\.a|\.a|\.lib) Obviously this is wrong. It should be using the path, /home/build/build/freedv/external/dist/lib, directly without prepending anything. Help! Thanks, Richard
