frontend error #35

Closed qarlosalberto closed 2 months ago

One TerosHDL user is having some problems with yowasp-yosys, but I can't find the error. Have you any idea about what could be the error? He is using Windows.

That is not specific to yowasp-yosys. This happens if you pass a literal ; as an argument to Yosys:

$ ./yosys ';'

ERROR: Can't guess frontend for input file `;' (missing -f option)!

So, the issue is somewhere in your command line handling code. I don't know where exactly but calling cmd.exe twice looks suspect.

Thanks! I have a good starting point.
