Hi all, first I wish all of you a Happy New Year.
I investigated the cause of the issue with displaying SVG (including our own icons in Users Guide) on-screen. IMO the root cause is the existence of two ways to use the configured converters: 1. the conversion process to load external material to present it on-screen (build_script in GraphicsConverter.cpp) and 2. the conversion process to prepare external material for use by external programs like LaTeX (Converters::convert) Both are using the utilities detected by lib/configure.py. But the meaning of the „$$i“ and „$$o“ placeholders is different. (1) is passing the complete absolute path of input and output file. (2) is operating in the temporary directory and uses relative path names only. On Mac the inkscape binary is a shell script itself and it’s not working with relative path names for input and output files. Therefore I added the prefix „$$p“ in front of the names to get absolute path names. Unfortunately this breaks the conversion (1). One possible solution for the current issue is it to change (1) to replace „$$p“ with an empty string. Is this a good idea or is some more fundamental change to unify the converters to prefer? Any other ideas?
