Yes, I agree. Considering how uncommon UWP configuration is, I think it is good enough that clang handles it only with lld. I think it'll worth to mention when I'll try to write README for winstorecompat.
So, the only issue that remains unsolved is gcc with -lwindowsapp. ________________________________ From: Martin Storsj? <[email protected]> Sent: Tuesday, November 25, 2025 6:06 AM To: [email protected] <[email protected]> Subject: Re: [Mingw-w64-public] A few questions about UWP apps and winstorecompat On Mon, 24 Nov 2025, Kirill Makurin wrote: > However, it seems that clang's -lwindowsapp handling works only with > lld.

Yes, that sounds about right. It's possible to make it work by manually passing e.g. "-lwindowsapp -lmsvcrt -lmingwex -lwindowsapp" or something like that, repeating the same library multiple times (like the built-in defaults do), but that's also quite inelegant. Given how uncommon it is to target UWP, and how it works fine when using lld, I haven't spent more time on improving the situation. There's a recent fix for the handling of CRT parameters, see https://github.com/llvm/llvm-project/commit/7f470586e10543aa12efc7e04d4d4ac814eaca35. The same logic could be applied to -lwindowsapp as well, making the compiler insert that option at the same place where -lkernel32 and the others would have been. > If I understood correctly, Pali wants to propose a new option to gcc, > -msysdll=, which would allow to replace library that follows mingw-w64's > -l flags.

I think that might be reasonable, but I haven't thought it through fully. // Martin _______________________________________________ Mingw-w64-public mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mingw-w64-public _______________________________________________ Mingw-w64-public mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
