Hi Yavor, Thank you for the answer. I was able to get the source from Debian repo and got it compiled.
But after the installation, the app cannot be opened : it failed with a segmentation fault after many warnings about 'incorrect signature'. Here is the output : pi@raspberrypi:~ $ openapp HelpViewer 2020-06-23 21:45:13.775 HelpViewer[3131:3131] styleoffsets ... guessing offsets 2020-06-23 21:45:13.790 HelpViewer[3131:3131] styleoffsets ... guessing offsets Calling [NSApplication -hide:] with incorrect signature.
