Not sure if it is, would be good to see if this solution works for other problem programs… For TexStudio, I found 3 packages are needed, after they were installed I was able to restart TexStudio and have it compile into a preview window. Keep in mind this is only for pdflatex compliing, this is my first time using Tex in general but I know there are lots of variations within it that this may or may not address.
Install TexLive & TexStudio
And these 3 additional packages from the OM repositories:
texlive-dehyph
texlive-l3backend
texlive-ec
The first is a German hyphenating pattern file, just a guess but this might be necessary only because of a --strict setting in a config file somewhere. It installs with another extra dehyph package automatically.
the second is the Latex3 backend driver, sounds important in an obvious way.
and the third is a font package. The default font package in the TexLive install appears to be Texlive-collection-basic but that doesn’t include the ec fonts… If the basic package were exchanged for texlive-collection-fontsrecommended i think that would include the ec fonts.
Also, for some reason the first try to compile may not appear in the preview but the second try it should.
ALSO also, installing TexLive per these instructions also works, but will take up more time to install and space to use, but may be more reliable at the time of this writing:

If you do it that way it’s important to add the PATH, I made a texlive.sh script and put it in /etc/profile.d/texlive.sh
