Precompiling Oscar InitError: GAP variable _JULIAINTERFACE_ERROR_BUFFER not bound

[JuanCaGC]

Hello, first of all the module is the best.
I was trying to install everything on a new computer and I found this error.
I have done the basics of updating. I have also deleted everything and reinstalled, and I am still having the same error. I would appreciate any solution.

Please report the output of Oscar.versioninfo(full=true).

Are you using WSL by chance?

[benlorenz]

Oscar.versioninfo() will probably not work, but julias versioninfo(verbose=true) would be good, together with using Pkg; Pkg.status().

Yes, I am using a WSL

[fingolfin]

The problem is caused by the Windows path C:\Users\oipli\AppData\Local\Programs\Julia-1.8.5\bin being in your Unix PATH environment variable. That confuses GAP when it tries to parse PATH. It may confuse other tools, too (the : is used as separator, so it will be parsed as two entries, C and \Users\oipli\AppData\Local\Programs\Julia-1.8.5\bin).

[JuanCaGC]

it worked thank you

[orebas]

Hi there, what is the fix for this? WSL seems to stick a bunch of windows directories into the PATH environment variable by default. So it seems like GAP will be broken on any WSL (btw, I have not noticed any other packages breaking.)

[orebas]

I was able to change the default path setting on WSL (leaving this here in case this issues shows up in a search). One can add
the below to the file /etc/wsl.conf
[interop] enabled=true appendWindowsPath=false

as documented here: https://learn.microsoft.com/en-us/windows/wsl/wsl-config

[orebas]

However, I am still getting an error. Here is the error:

Threads: 8 default, 0 interactive, 4 GC (on 12 virtual cores)

You might be hitting a different issue now, see oscar-system/GAP.jl#960. You can try --gcthreads=1 as a workaround.
Julia default should be 1 thread and not 8.

For me GAP loads fine in WSL.

Edit: I also have plenty of /mnt/c/Program Files... paths in my PATH there and that doesn't seem to hurt. I guess as long there is no real windows path with \ in there it should be fine, I don't really know how that one ended up there for you. (Manually adding C:\something breaks GAP)
