Introduction
LaTex together with OpenBSD is a simple task. This article is going to be rather short.
Setup
Install the following packages:
pkg_add texlive_texmf-full texmaker zathura zathura-pdf-poppler
These packages install the complete LaTex packages. texmaker is a very good LaTex editor. You can also compile and display the resulting pdfs with it. zathura is a good pdf viewer.
That is it.
Conclusion
Installing LaTex on OpenBSD is a piece of cake. Everything is configured automatically for texmaker.
