wxWidgets 3.3.1 can only be used in the ucrt platform, not the mingw64 platform?

Hi, when I looked at the packages of the msys2, here: https://packages.msys2.org/base/mingw-w64-wxwidgets3.3

I see it only has 3 platforms: ucrt, clang64, clangarm64.

While if you looked at the wxwidgets 3.2 ( https://packages.msys2.org/base/mingw-w64-wxwidgets3.2 ), I see extra platforms: mingw64.

Is it because that the 3.3.1 will support the dark mode, and the dark mode API are only supported by the ucrt library?

Thanks.

I know that wx3.3.1 samples crash on exit if you use MinGW with MSVCRT, see this issue.

Thanks for the reply. I have seen your issue report before, but when I try to search the issue by your user name "Miguel Gimenez", I couldn't find it. Oh, I see your nickname in github is: "wh11204".

So, it crashed on 64bit Windows 7(Am I correct? I guess you are using 64bit Windows 7) with a 32bit compiler: i686-w64-mingw32, which is using MSVCRT library.

For me, I would still try to use a 64bit compiler which is MSVCRT library not UCRT, and I'd try on a 64bit Windows 10 PC first. Does anyone has tried this combination before?

I build Code::Blocks under MSys2 Mingw32 and MINGW64 about once a month; but, I really do not do enough testing to be sure it works.
Windows 10 64 bit

I just did the test, and when I run the "minimal.exe" from the wx samples, I don't see the crash in my 64bit Windows 10 PC.

I'm using msys2/mingw64's gcc compiler 14.2.0, which is using MSVCRT library to build the wx 3.3.1 library and the minimal sample code.

Hi, Tim, thanks for the info.

My question still remains, if wx 3.3.1 works under MINGW64 platform, why msys2's package does not supply wx3.3.1 in this platform.
