I installed texlive-metapost in Linux Mint (similar to Ubuntu), and each time I compile a MetaPost figure which contains a label, the compiler finishes the job, but the picture is not saved as ps, i.e. I cannot open it. I am thinking that maybe mpost does not compile latex formulas, but the compiler still doesn't give a result even when the formulas do not contain Latex. What is the problem, and what can I do?
I noticed that in the online live previewer which can be found here the mp file compiles with no problems. Is there a similar compiler for MetaPost, which can be installed (for which you write the code in the left side and in the right side you get the preview, like Gummi?)?
