I am using Texmaker 4.3 (downloaded from their website) and Texlive 2014 (also downloaded) on Ubuntu 12.4 fork ElementaryOS in 64bit.
I recently completely reinstalled my OS and compiling a PDF in Texmaker does not work (it did work before the reinstall, but that may have been Texlive 2013 or even 2012, though I am not sure. also it was 32bit). By "not working" I mean that if I click the PDFLaTeX button, my PC works and I see latex output, but there is no pdf created (and if one exists previously, it's not changed). I see no conpile errors. I google a bit, but I was not able to find a solution. My configuration of Texmaker is
latex -interaction=nonstopmode %.tex pdflatex -synctex=1 -interaction=nonstopmode %.tex
Some more information: Compiling works in Terminal (with pdflatex name.tex). For the current document I don't have a bibliography, but in general I use biblatex with biber.
