Failed to Build wxPython 4.2.1 on WOA

[ZYPThu]

Operating system: Windows 11 on ARM
wxPython version & source: wxPython 4.2.1 downloaded by pip
Python version & source: Python 3.11.6 for ARM64 stable release download from python.org

Description of the problem:
I try to build wxPython 4.2.1 on Windows 11 ARM, but it failed. I already have vsbuild tools installed.
The information are as following:

You probably have the wrong 'attrdict'.
Try attrdict3 instead.

See https://github.com/wxWidgets/Phoenix/blob/master/requirements/devel.txt

The build process also requires a bash. On my Windows I have a bash.exe on the path which will just print a message about WSL. Unfortunately wxPython tries to take this one instead of the one from cygwin.

[DietmarSchwertberger]

On more trap to avoid:
When you install sip, you also get some binaries.
E.g. "...path..to..python\Scripts\sip-build.exe".
The Scripts dir needs to be on your path.

Thanks! That's really helpful.

Sadly I still cannot build this package on my own. The new problem seems caused by Setuptools probably. From the error code it seems that the setuptools does not work well for Python 3.11 ARM64. Here are the error codes.

Unfortunately, it looks like the Phoenix build process assumes 64-bit is x64, see here:
https://github.com/wxWidgets/Phoenix/blob/master/build.py#L1718

You could try tweaking those arguments. Unfortunately, arm64 w/ Windows is a rare thing, so not sure I'd have access to a machine to troubleshoot.

[RiadhKHEDHIRI]

Windows on Arm is getting traction.

I managed to tweak build.py to make it ARM64-compatible.

The project compiles the C code, but the build fails at the waf level. Note: I am using Visual Studio 2022 on a native Windows on ARM machine.

First, I used platform.uname() instead of platform.architecture() otherwise I cannot tell if I am on ARM64.

Then, I added some branching to account for the new platform. Basically, whenever I see x64 I add arm64. Below are some examples; they are not exhaustive.

In the checkCompiler(), I have trouble getting the path to VC++ in the Hostarm64/arm64 directory. I keep getting the one in Hostx64\arm64, which didn't play well with the C code. So, I temporarily hardcoded the path.

I think it is setuptools issue.

The command run is python .\bin\waf-2.0.24 --msvc_arch=arm64 --python=C:\Users\X\PycharmProjects\Phoenix\.venv\Scripts\python.exe --out=build/waf/3.12/arm64/release configure build

I tried to tweak the waf script by hardcoding paths, but it seems compiled or obfuscated. Idk.

Any clues, please? Hope it helps

[Max-RM]

they are not exhaustive.

I think I did mistake in some places of file. Can you send your build.py file here?

[Max-RM]

Any clues, please?

in the last attempt, I edited incorrectly build.py now I edited it correctly and got the same result as you:

msvc: Impossible to find a valid architecture for building ['msvc 17.11'] - ['msvc 17.11']
(complete log in C:\Users\MaxRM\Downloads\wxPython-4.2.2\build\waf\3.9\arm64\release\config.log)

from C:\Users\MaxRM\Downloads\wxPython-4.2.2: msvc: Impossible to find a valid architecture for building ['msvc 17.11'] - ['msvc 17.11']

And here full logs of my errors:
config.log
wxPython000.txt

I will ask ChatGPT to help with this error, but almost sure that it will not help :(

Working on this. In addition to some changes in wxPython, some changes need to be made in WAF, and possibly in setuptools.

FINALLY!

Thank you great hero.

@swt2c can you also make port for Windows 10 ARM32?
Because there is unofficial ARM32 Win builds of Python 3.12

Is there MSVC for ARM32? I can't find any evidence of it.

Hi.
It was ported unofficially several days ago. Although it has many problems right now, and need to talk with it's creator Jeybee to install it correctly.

Btw maybe there is way to patch wxPython to force it use llvm-mingw instead?

Hi again. If you already have successfully compiled wxPython to ARM64 Windows, can you send pre-compilled .whl file here?

Thanks alot!!!
(Unfortunately still need to compile some other projects to run Amulet Map Editor on ARM64 Windows and make some changes like you did for wxPython package, but all this situation isn't related with wxPython so doesn't matter).
