Why is MnSymbol not loading Type 1 fonts?

Question

I am trying to typeset a document with only Type 1 fonts in the resulting PDF. I'm using the MinionPro package, which calls MnSymbol for math fonts. Even though the Type 1 MnSymbol fonts are installed in ~/texmf/fonts, pdfLaTeX insists on using pk files and producing Type 3 fonts in the PDF output. (I can see this by looking at the log file and the PDF in Evince.)

Here is a MWE:

\documentclass {minimal}

\usepackage {MnSymbol}
\usepackage[T1]{fontenc}

\begin{document}
First, some text. 
Now some math:
$ a^2 + b^2 = c^2.$
\end{document}

The same problem is produced by replacing MnSymbol with MinionPro, and it's worth noting that the log file shows Type 1 Minion Pro fonts files when I do that. So MnSymbol seems to be the problem. More evidence for this: if I use no math symbols in the document, all fonts in the PDF are Type 1.

I have found this similar question, but the solution proposed there (i.e., run updmap) does not seem to work for me. (Perhaps that problem was specific to MikTeX; I'm running a slimmed-down version of TeX Live on a Linux machine.)

A related troubling fact is that MnSymbol.map is nowhere to be seen in the output of updmap-sys --listmaps, though MinionPro.map is. So I'm not even sure how pdfLaTeX is finding MnSymbol in the first place.

Any suggestions?

Answer 1

The map-file of the font has not been enabled correctly for an unknown reason.

Run on a command line

 updmap-sys --enable Map=MnSymbol.map

(this is for a texlive system, in miktex it works a bit differently).
