Hi,
It looks like the call to the "latex" command somehow fails. Can you
make sure that it is correctly set up, and in your $PATH?
(You can also set the path, cantor uses by modifing your cantorrc file
in ~/.kde/share/apps (or something similar), just add a line saying
LatexCommand=/some/path/to/latex inside the [Cantor] group)
Also, the debugging output you posted is not very helpful, as it
doesn't really contain anything that comes directly from cantor.
To enable cantors debugging, you can run "kdebugdialog" and make sure
anything with cantor in its name is enabled.
That way you should get way more debugging output, telling you
anything cantor is doing. If you post it here, I might be able to help
you more.
