Call to unimplemented function ucrtbase.dll.crealf

[juliowissing-iis]

Hello!

We are using pywine to run pyinstaller in Linux for a Windows package in a CI Pipeline. It worked flawlessly until recently when the following error appeared:

wine: Call from 00006FFFFF463EF7 to unimplemented function ucrtbase.dll.crealf, aborting
wine: Unimplemented function ucrtbase.dll.crealf called at address 00006FFFFF463EF7 (thread 05a0), starting debugger...
WineDbg attached to pid 0000
Unhandled exception: unimplemented function ucrtbase.dll.crealf called in 64-bit code (0x006fffff463ef7).

Would you happen to have an idea of how to fix the problem?

Trying to use scipy? This looks like a duplicate of #65

Thanks for the link to the other issue. I am not using Scipy, but a different package may produce the same error. The weird thing is that I could use pywine to run pyinstaller in a Linux environment before, and it just recently stopped working. I'll have to dig deeper into the dependencies and changelogs.

You might want to check the backtrace leading to the error. Since crealf is part of Microsoft's custom complex number implementation, whatever library is calling that will probably call other complex number APIs later... It might be nice if Wine would implement all those APIs, but the API surface is quite large... (Even if most individual functions are probably quite simple)

Thank you for the suggestions. I'll have look!

I solved this issue by using wine devel, i.e. forking this repo and building the Dockerfile from tobix/wine:devel instead of wine:stable.

@TobiX would it be feasible for you to set up a branch pywine:devel?

@hpdeandrade That's expected, as I mentioned in #65 (comment) Wine has started adding those methods in Wine 10.1, so this will work.

I'm currently not planning to add more branches, especially not for such a corner-case.
