NVC / OSVVM / Windows / MSYS64 / GTKWave - doubts

[jerzygbur]

Hallo,
My adventures starts with these tools, mentioned in subject.
I've cloned NVC from github, builded and install in Windows/MSYS2/CLANG64 environment.
I've install libraries for OSVVM (nvc --install osvvm) - First issue - it installed OLD library not last.
After manual upgrade (copy) and after installing some tools for TCL, it starts working.
Next I wanted to see some waveforms, so installed GTKWave - still inside MSYS2.
Second issue - the gtkwave doesn't understand FST file. I tried to use fst2vcd to translate it. It's not working inside MSYS2. When I use Windows' tool fst2vcd -o file_out.vcd -f file_in.fst it translate it. I can take and use this file_out.vcd in gtkwave inside MSYS2. Funny.
Am I doing something wrong?
Have you had similar problems?
Kind Regards,
Jerzy Gbur
