Error building stack projet in vs code

[houdelou]

Hi, it seems the language server is unable to build the project. I suspect it is a permission issue. I had permissions issue in the past in the appdata folder. Is there any way I could change the outputdir and -o to another directory ?

Here is the error I get in vs code :
readCreateProcess: stack "exec" "ghc" "--" "-rtsopts=ignore" "-outputdir" "C:\Users\houde\AppData\Local\Temp\hie-bios-8f902f3286e2fa30" "-o" "C:\Users\houde\AppData\Local\hie-bios\wrapper-340ffcbd9b6dc8c3bed91eb5c533e4e3.exe" "C:\Users\houde\AppData\Local\hie-bios\wrapper-340ffcbd9b6dc8c3bed91eb5c533e4e3.hs" (exit 1): failed

VS Code 1.71.2
Windows 10
Stack 2.7.5

Thanks

Hi, thank you for your bug report!

You can overwrite the directory of -o via the env variable HIE_BIOS_CACHE_DIR. Is the directory in -outputdir also problematic? We don't currently have a built-in way to overwrite that, it uses the system TMP directory, you can overwrite that for HLS.

Thanks, I see the -o has changed accordingly. I still get the same error though. Maybe this is more of a PC problem if no one has ever had this problem except me.

I also saw this error in the output window :

C:\sr\appdata\wrapper-340ffcbd9b6dc8c3bed91eb5c533e4e3.hs:1:8: error:
Bad interface file: C:\ghcup\ghc\9.0.2\lib\x86_64-windows-ghc-9.0.2\base-4.15.1.0\Prelude.hi
magic number mismatch: old/corrupt interface file? (wanted 33214052, got 1)

Huh, that's not great. @hasufell is ghc 9.0 broken on windows or something?

[hasufell]

Maybe corrupted file. Windows is a disaster wrt file locking, antivirus etc

[fendor]

So, best is to re-install? ghcup rm ghc 9.0.2 followed by ghcup install ghc 9.0.2

[houdelou]

Yes, I reinstalled it and upgrade it at the same time and it is working now ! Thanks for your help.

Then I'll close this issue for now, feel free to reopen
