[Tex/LaTex] LaTeX compilation of simple document fails


I am just starting to work with LaTeX for the first time, so I apologize if my question is trivial.

I recently got a first .tex document from my supervising tutor, with the request we compile it twice via pdflatex so that references will work.

After manually installing the TeX Live 2012 distribution, pdflatex fails to compile the document. From what I can understand, the problem is a some kind of missing font:

This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian)

I am pretty sure I set up TeX Live correctly; I also included the distribution in my PATH variable so that the binaries should be found. What is going wrong? I am pretty clueless and thankful for any hints.

Update 1: I installed the TeX Live distribution into /usr/share/texlive/2012/i386-linux, and I see the path /usr/share/texmf-texlive/tex/latex/base/ appear instead – could this be a sign that the pdflatex command is looking in the wrong places? Again, since I have (yet) to learn what the files are used for, I don't know if this hunch makes any sense.

Update 2: I realized the pdflatex command invoked some TeX Live 2009 binary that was roaming around in my system. After removing those packages (hopefully without anything remaining), I will try again and see what happens.

Update 3: Through some weird bash caching mechanism, it was still invoking the old binary even though the PATH was set correctly. I removed all of the texlive packages from my package management system, and finally got it working.

A quick google search on ecrm1000 gives good results:


Both give the same solution: you need to install texlive-fonts-recommended using your package manager
