Gitlab News

Folks, As you may have noticed, now that the ARM64 support is done (just kidding), I've picked up the work on the Gitlab migration: 1. The Wiki has been moved to Gitlab, it's now at [1]. Existing URLs to the previous Wiki are redirected to the appropriate page. There are also separate Wikis for appdb, vkd3d and wine-staging, under their respective project pages. As part of the migration I've done some minor edits, but most of the Wiki is badly out-of-date, and could use some love. Help is welcome! Check the Writers page [2] for details on how to contribute. 2. We are now hosting the Mono project on the WineHQ Gitlab [3]. Please join me in welcoming the Mono developers to our community! 3. We have new hardware for the Gitlab server, which is now noticeably faster. Thanks to Jeremy Newman for setting this up! This also made it possible to enable robots.txt again so that our content is indexed. The next step will be to install new hardware for the Gitlab runners to offer more CI bandwidth. 4. The Gitlab issue tracker is currently disabled because it was attracting too much spam. I'm going to re-enable it, first for use by Mono, and then ultimately also for Wine itself. To fight the spam I'm planning to add an explicit user verification step, modelled along the procedure used by Freedesktop.org [4]. 5. As part of the new sign-up process, I think it would be a good idea to have an explicit Code of Conduct to spell out our expectations. Instead of reinventing the wheel, I propose that we adopt the Contributor Covenant [5] that many other projects (including Mono) are already using. Thoughts? Questions? Comments?

Apple Silicon compilation
by robert lippmann April 9, 2025

April 9, 2025

Hi all, I tried to update the wiki to document how to compile Wine on Apple Silicon, but I’m not sure if it went through. Basically, you need to add lld (which pulls in llvm) in addition to the other build dependencies So: brew install lld Then: PATH=`brew —prefix llvm`/bin:`brew —prefix bison`/bin:$PATH Then everything compiles. You probably don’t even need Xcode. And you probably should have Rosetta2 installed. I haven’t actually been able to get it to run yet, though… — Rob

Powrprof patches
by robert lippmann March 11, 2025

March 11, 2025

Hi all, I’ve been looking at possibly submitting some patches for powrprof.dll and had a couple of questions/looking for guidance about some issues. Namely: 1) Default power profiles are stored in the registry under HKLM\System\CurrentControlSet\Control\Power. The subtree is pretty huge (about a 1.5m .reg file when I exported it. The GUIDs used appear to be the same from machine to machine for the default power stuff. Is there a way when Wine bootstraps to load these ? If the answer is no, is hardcoding permitted? 2) According to https://learn.microsoft.com/en-us/windows/win32/power/power-management-func…, the functions implemented are for Vista and earlier. Can I (initially) stub the newer functions? 3) In the cases where the functions are trying to set values, can I just simply return success since we aren’t going to actually change the values on the host? They’re probably doing other things under the covers, but it would take me some investigation to see what. Thanks, Rob

I’ve also been playing with building wine on Apple Silicon (Sequoia), and though I was also able to successfully build for x86_86 (with Rosetta 2), it seems that I’m having issues with fonts that are basically making running anything with a GUI impossible. I can run cmd.exe without a problem, but things like explorer and notepad either don’t show up at all or open with an essentially blank window. If I configure and build with freetype2, I get repeated errors about not being able to find the library even though I have it installed: Wine cannot find the FreeType font library. To enable Wine to use TrueType fonts please install a version of FreeType greater than or equal to 2.0.5. http://www.freetype.org Then, eventually the following error: 0140:err:syslink:SYSLINK_SetFont Failed to create link font! Configuring without freetype still results in the above SYSLINK_SetFont error. Attempts after the I’ve found a few vague posts online from long ago about needing the 32-bit freetype2 libraries, but is that even a possibility anymore since Apple removed support for 32-bit code? I’ve also come across hints that System Integrity Protection might be getting in the way somehow, but I’m really not familiar with the details of how that works. In any case, I have just set up a spare Linux box so I can hopefully have a smoother time getting started on contributing, but I was excited about working on this in a macOS environment. After seeing Rob’s post, I figured I would chime in just in case anybody has any tips. Forgive me if I am just way off in the weeds; it has been a long time since I've compiled any C code on Linux, much less on macOS. -Don > > From: robert lippmann <robert.lippmann.development(a)gmail.com> > Subject: Apple Silicon compilation > Date: February 23, 2025 at 7:55:59 PM EST > To: wine-devel(a)winehq.org > Reply-To: wine-devel(a)winehq.org > > > Hi all, > > I tried to update the wiki to document how to compile Wine on Apple Silicon, but I’m not sure if it went through. > > Basically, you need to add lld (which pulls in llvm) in addition to the other build dependencies > So: > > brew install lld > > Then: > PATH=`brew —prefix llvm`/bin:`brew —prefix bison`/bin:$PATH > > Then everything compiles. > > You probably don’t even need Xcode.
