I fix the problem regarding the conflict in libraries
How did you do that?
When I try to run DucoGUI.pde I get the following error message:
The Geomerative library is required for RShape, so it appears that throwing away SVG Export (part of Processing) is your only option and I have no idea if that is even possible.
Observation:
There is a fisica example called Letters which also uses this font and generates the same error message when trying to run it. However when the two apache font import calls are REMmed out it runs without error.
I tried remming out the font calls in both of the RFont.java files found in Geomerative but the error message persisted. The only way I could get DucoGUI.pde to run was to leave out the Geomerative import, but then RShape is missing and there are other problems. I would be interested to know how you resolved the duplicate library problem.
