Hey 👋🏻,
Any news on this topic ?
cc Rich Lander (@richlander), given that we now have official support for .net 10/alpine/docker, I think it would be great to prioritize this. Currently, it is not possible to install PowerShell on alpine/arm64, and PowerShell is one essential tool for .NET developers.
Travis Plunk (@TravisEz13) Steve Lee (@SteveL-MSFT) could you help us move forward on this issue? It would be really great to unlock the use of PowerShell on this alpine/arm64 platform.
Reacted by Logan Bussell, backtrack5r3 and Chongyi ZhengFor the record I was able to make it work by doing the following:
1- On a Win11/x64 machine I cross-compiled
powershellto targetAlpine/linux-musl-arm64:- I updated the build script to add the proper
linux-musl-arm64target. - Then I ran:
Import-Module ./build.psm1 Start-PSBuild -Runtime linux-musl-arm64 -Configuration Release
- I had several issues while restoring packages. Perhaps the root issue is on my side but after playing with the
nuget.configand manually downloading some of them to my cache, I was able to build everything. Perhaps thepowershellregistry is not up-to-date with latest .net packages. I spotted only later that there is aSwitch-PSNugetConfig -Source NuGetOnly.
2- When trying to run
pwshon the targetAlpine/linux-musl-arm64machine, I got:Unhandled exception. System.TypeInitializationException: The type initializer for 'System.Management.Automation.Tracing.PSEtwLog' threw an exception. ---> System.TypeInitializationException: The type initializer for 'System.Management.Automation.Tracing.PSSysLogProvider' threw an exception. ---> System.DllNotFoundException: Unable to load shared library 'libpsl-native' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable: Error relocating /opt/microsoft/powershell/7/libpsl-native.so: __realpath_chk: symbol not found Error loading shared library libpsl-native.so: No such file or directory Error loading shared library /opt/microsoft/powershell/7/liblibpsl-native.so: No such file or directory Error loading shared library liblibpsl-native.so: No such file or directory Error loading shared library /opt/microsoft/powershell/7/libpsl-native: No such file or directory Error loading shared library libpsl-native: No such file or directory Error loading shared library /opt/microsoft/powershell/7/liblibpsl-native: No such file or directory Error loading shared library liblibpsl-native: No such file or directory- Indeed
libpsl-nativeis required and was not available in my setup forAlpine/linux-musl-arm64. The regular build is giving an arm64 glibc-based one ! - So I cloned your
PowerShell-nativerepo and recompiled it on the target machine using the following:
apk update apk add git build-base gcc abuild binutils git python3 bash cmake apk upgrade git clone https://github.com/PowerShell/PowerShell-native.git cd PowerShell-native/src/libpsl-native cmake -DCMAKE_BUILD_TYPE=Release . make -j
- then copied
libpsl-native.sonext to my custompwsh
And
powershellwas working !So it would be really great to industrialize all this so that we can officially benefit from PowerShell on this platform. I may not be aware of everything, but from experiments above, it doesn't seem like a tremendous amount of work for someone familiar with this repo.
Thank you for your help!

Hey! We needed this for our project, so we created an Azure Pipeline that builds PowerShell for linux-musl-arm64.
The pipeline uses Docker buildx + QEMU to build libpsl-native.so natively on ARM64 Alpine, then cross-compiles PowerShell and packages everything together.
Here's the pipeline configuration: https://github.com/proxy/gist.github.com/tomflenner/60d5f4d93852d3040adfe95c2f662fb0
Hope this helps others who need Alpine ARM64 support!

Azure Pipeline to build PowerShell 7.5.2 for linux-musl-arm64 (Alpine ARM64) using Docker buildx, QEMU emulation, and cross-compilation - azure-pipelines-powershell-alpine-arm64.ymlReacted by Sebastien Lebreton and obsidience
Steps to reproduce
Expected behavior
Find a build named like “powershell-7.5.2-linux-musl-arm64.tar.gz”.
Actual behavior
No ARM64 build is provided. Can’t install PowerShell.
Environment data
A ARM64 glibc is provided, ex “powershell-7.5.2-linux-arm64.tar.gz”. Only musl is missing. ARM32 is also not provided but I don’t know is there is really a use case there.
