I'm using Debian WSL, the version of the gcc I have is gcc (Debian 10.2.1-6) 10.2.1 20210110 and I've already set an env

Is there something I set wrongly o missing?

[mloubout]

If your version of gcc is just called gcc then you can just use the standard DEBVITO_ARCH=gnu , the custom one is only needed if your compiler have non standard name. I have JUDI setup on WSL at home and it work pretty well so not quite sure what the issue is here. Did you run this through vs-code or in the wsl debian terminal?

[jddorellanao]

I did what you said and I work perfectly. By the way, I run this through vs-code. Thanks for the quick reply. Cheers
