You may use mingw64 to compile it on Windows ( Which is mentioned in #5, but I not try it, suggest you to use it on Linux )

cross compile for windows with mingw on linux?

I guess you can compile it directly on Windows with MSYS2 or something?

commented on May 24, 2024
Ok I'll try MSYS2.
I've also made a fork for using CI to compile for Windows using MSVC, can you check out why pkg-config is not finding unicorn2 even after compiling it :)

commented on May 24, 2024
Because the command pkg-config only exists on Linux.
I suggest you to take a look at #4, which use the dev branch of unicorn that can deal with the situation that pkg-config doesn't exist.

Ah right. he also faces the same error. Should we try using mingw then?

You can build udbserver in your CI after applying this patch:

@bet4it Thanks a lot. It worked :D 👍🏼

Btw, the python bindings cant find the header during compilation.
Edit:
Added the following lines to fix the missing header, but now i'm getting linker errors:

#4 is the promising way to build python bindings on Windows, let's wait until it lands, or you can change base on it.
By the way, can the C bindings work on your computer?

If you don't mind, are you on telegram / discord / matrix? That way it would be a bit more easy to debug the errors.

commented on May 24, 2024
I just built udbserver on mingw64 and everything works fine like on Linux.
As for the __CxxFrameHandler3 error, do you mix the use of mingw64 and MSVC? And could you try to set panic = "abort"? (rust-lang/rust#45492 (comment))

I'm sorry I don't have such accounts. Maybe we can use something like gitter? But it seems that it has little difference with chatting on Github😅

Hello 👋🏼. I just managed to run the udbserver under msys2, but how can i use it under windows python?
Can i package the python module with the dependencies somehow?

commented on May 24, 2024
Oh, I really don't know how to do it, but as I said before, if you want to do it, remember to base on the work #4 had done.

commented on May 24, 2024
I just extracted the unicorn package from MSYS2 and the build folder from msys2 udbserver and pasted it into my windows Mingw64, and added compiler=mingw32 to distutils.conf file. Then compiled the python and c bindings, and it works :)

commented on May 24, 2024
Great! So this can only be used in MSYS2/Mingw64? Or you can use it directly on Windows?

It can be used in Windows Python installation! however, I had to copy the include folder to my python install path, and libs to python libs folder.
This can also be done by packaging these files inside the .egg file. You need to edit setup.py to include folders and add them to path. Like unicorn does for its windows pip package. On extracting the unicorn Windows pip package i found "include" "lib" and dll files. I tried to edit the setup.py to do it myself, but it doesn't work for some reason.
