[Pkg-kde-extras] Bug#746552: Bug#746552: kile: Consider not hardcoding Okular as PDF viewer

[Ralf Jung]

Hi,

> It would be great if Kile PDF viewing worked by default on non-KDE installs - particularly as KDE is not the default for testing.  Currently, after install kile, in order to view a PDF generated by kile, one has to modify the PDF tool (settings->Conf. Kile->Tools->Build->ViewPDF->Command), or attempts to view the generated PDF fail with a message in the log area "failed to start".

exo-open is Xfce-specific.
However, there's xdg-open, which is more general and would therefore
IMHO be more suited.

Kind regards
