Hello Edward,
As I did report previously there are issues with the devel' branch on Linux [e.g here].
I did not push harder from my side earlier, since I do have a somewhat special environment setup ...
However now I did prove that my environment is not the issue. - See attached log ...
Again I did verify that issue on Debian Linux as well as Fedora Linux.
I will create a GH issue for it & link this conversation to it !
With kind regards,
Viktor

I did not have any trouble with Leo on startup except for this anomaly. I have some @file nodes in my workbook.leo file that don't exist in the Linux system. Leo complains that they are missing but the file it reports is very wrong. E.g., if the @file node is
@file screen_capture.py
Leo reports the missing file as
/home/tom/.leo/c:/test/python/screen_capture.py
If this is actually how Leo on Linux is constructing paths from relative paths for @files then something is very wrong. If it's only a reporting problem then it needs to be fixed.Viktor Ransmayr

There are other problems, which I reported for the 'devel' branch on Linux, e.g with '--gui=console" ...
However I did use this example, because it NICELY shows that the 'master' branch (v6.8.8) does not have the problem - but - the 'devel' branch (v6.8.9-devel' does have it !
With kind regards,
Viktor
