Not sure if this is a current issue or if there's a known resolution for such.

Okay, followed these instructions precisely (with cmd), and the install into cabal package cache worked. But is there any way to get this to work for powershell, since many users have migrated to powershell / windows terminal from cmd?

[liamzee]

Powershell examples:

$env:PATH += ";C:\ghcup\msys64\mingw64\bin;C:\ghcup\msys64\usr\bin;%PATH%"
$env:PKG_CONFIG_PATH ="C:\ghcup\msys64\mingw64\lib\pkgconfig"
$env:XDG_DATA_DIRS="C:\ghcup\msys64\mingw64\share"

This is still failing, tried a new install on 9.6.2,

Failed to build gi-gdk-4.0.7. The failure occurred during the configure step.

I think the cmd version still works, not sure what's wrong with the powershell version.

[liamzee]

might have been that I failed to set $env.PATH, as opposed to $env.Path, which was what I was using for a bit.

[liamzee]

Still not working even with $env:PATH. So I guess this is an issue with powershell / my comprehension of powershell, might someone have a fix?

[liamzee]

ghci> :set -package gi-gtk
package flags have changed, resetting and loading new packages...
ghc-9.6.2.exe: Could not load `libgobject-2.0-0.dll'. Reason: addDLL: libgobject-2.0-0.dll or dependencies not loaded. (Win32 error 126)

*** Exception: loadArchive "C:\ghcup\msys64\mingw64\lib\libgobject-2.0.dll.a": failed

Looks like this works fine on cmd.exe, terribly on powershell. Ugh.

[liamzee]

powershell translation of:

$env:PATH="C:\ghcup\msys64\mingw64\bin;C:\ghcup\msys64\usr\bin;$env:PATH"
$env:PKG_CONFIG_PATH ="C:\ghcup\msys64\mingw64\lib\pkgconfig"
$env:XDG_DATA_DIRS="C:\ghcup\msys64\mingw64\share"

works. I'm busy trying to figure out how to get this to work via modifying system environment variables.

Thanks for digging into this! I am afraid I know very little of Windows myself, so I cannot really help, but if you figure this out please do add your findings to the wiki. I am sure other Windows users will appreciate it!
