In the examples/widgets folder I am running go get./.. but I keep hitting the issue below

Trying to build gi on windows but I keep running into issues with svg not finding the references to the mat32 matrix class. Any idea how to fix this?

sorry should be fixed now -- updated mat32 version to 1.0.3

Thanks Dr. O'Reilly that worked now. I was having an issue with the gcc compiler after that, but I found if you add the -buildmode exe onto the build command it works for windows. I'm going through your excellent course Computational Cognitive Neuroscience on youtube now and I think leabra is brilliant.

Thanks! finally added the -buildmode exe to Install instructions -- not sure if it is fixed or not yet.. golang/go#40795 seems a bit ambiguous
