I'm trying to run Cal 9.3.1 from source using Portable on win10.

Any background job I try (Create Catalog, FFF plugin, Calibre Convert) all fail with:

I don't know anything about icons.rcc, but it is a generated file.

This is the DOS bat file I use to start it:

"testport src"

set PYTHONIOENCODING=UTF-8

python makeplugin.py

"%CALPORT_DIR%\Calibre\calibre-customize" -a FanFicFare.zip

SET STARTINGDIR="%cd%"

cd "%CALPORT_DIR%\Calibre"
"%CALPORT_DIR%\Calibre\calibre-debug" -g

cd "%STARTINGDIR%"

Any guidance on getting this working?
