Windows ARM64- PocketSphinx

[arshiafreen090]

Description

I'm using native Python on Windows 11 ARM64 (Snapdragon X) with Python 3.12 ARM64.

Installing PocketSphinx with:

pip install pocketsphinx

falls back to building from source because there isn't a prebuilt win_arm64 wheel. The build then fails during the CMake/MSBuild configuration stage.

Environment

• OS: Windows 11 ARM64
• Architecture: ARM64 (Snapdragon X)
• Python: 3.12 ARM64
• pip: 25.0.1

Error

Building wheel for pocketsphinx (pyproject.toml) ... error

CMake Error at CMakeLists.txt:3 (project):
  Failed to run MSBuild command:

  C:/Program Files (x86)/Microsoft Visual Studio/18/BuildTools/MSBuild/Current/Bin/arm64/MSBuild.exe

  ...

  error : The BaseOutputPath/OutputPath property is not set for project
  'VCTargetsPath.vcxproj'.
  Configuration='Debug' Platform='ARM64'

*** CMake configuration failed

ERROR: Failed building wheel for pocketsphinx
ERROR: Failed to build installable wheels for some pyproject.toml based projects (pocketsphinx)

Expected behavior

It would be helpful if PocketSphinx provided official win_arm64 wheels on PyPI, or if there were documented steps for building successfully on native Windows ARM64.

Please let me know if I can provide any additional logs or test anything.

Hi! Yes, unfortunately there are some issues with GitHub's Windows ARM64 runners - it looks like someone opened a pull request to fix this, though, so I'll take a look!
