[solved] texlive doesn't work correctly, when lmodern is used

Question

Hi!
I've got a problem with texlive: When I use the package lmodern and my document contains mathematical symbols like integrals or sums or special chars like german umlauts, dvips and pdftex give me error messages and the symbols are not displayed correctly in the resulting document.
Here an example .tex-file:
\documentclass{scrartcl}
\usepackage{amsmath}
\usepackage{lmodern}
\begin{document}
$$\int_0^r e^{-x} \sin(x)\,\mathrm dx$$
\end{document}
dvips gives the following output:
kpathsea: Running mktexpk --mfmode ljfour --bdpi 600 --mag 1+0/600 --dpi 600 lmex10
mktexpk: don't know how to create bitmap font for lmex10.

</usr/share/texmf/dvips/base/tex.pro>. [1]
Also, a file named missfont.log is created and contains the following:
mktexpk --mfmode ljfour --bdpi 600 --mag 1+0/600 --dpi 600 lmex10
mktexpk --mfmode ljfour --bdpi 600 --mag 1+0/600 --dpi 600 lmmi8
mktexpk --mfmode ljfour --bdpi 600 --mag 1+0/600 --dpi 600 rm-lmr8
mktexpk --mfmode ljfour --bdpi 600 --mag 1+57/600 --dpi 657 lmmi10
mktexpk --mfmode ljfour --bdpi 600 --mag 1+0/600 --dpi 600 lmsy8
mktexpk --mfmode ljfour --bdpi 600 --mag 1+57/600 --dpi 657 rm-lmr10
I used lmodern several times in the past and it worked correctly. Maybe some update lead to this...
Can anyone confirm this problem or give some hints, how to solve this problem? I tried reinstalling all texlive packages, updmap, fmtutil...
Thanks for help!
Michael
EDIT:
Reinstalling all texlive packages didn't help. But uninstalling them, deleting all files in /usr/share/texmf* and reinstalling them did help. I don't know why, but the problem is solved. Sorry for the inconvenience.

Answer 1

The way some TeX-related font packages use updmap-sys to update TeX's font database (/etc/texmf/web2c/updmap.cfg) may cause this problem. For me, minionpro started to give similar 'missfont' errors when I upgraded texlive-latexextra.
I don't know the right/best way to handle TeX fonts and use updmap-sys in install files, however installing *.maps files into the /var/lib/texmf/arch/installedpkgs/ directory seems to be a more robust solution than calling updmap-sys with '--enable Map' or '--enable MixedMap' options. Adapting the code used in the build files of texlive-latexextra for minionpro solved the problem for me.
The steps I did:
Create *.maps file (minionpro.maps).
Modify  the PKGBUILD (modified minionpro PKGBUILD):
Add '$pkgname.maps' to the 'source' variable.
Add these lines to the top of the build() function:
install -m755 -d $pkgdir/var/lib/texmf/arch/installedpkgs
install -m644 $pkgname.maps $pkgdir/var/lib/texmf/arch/installedpkgs/
Update the 'md5sums' variable.
Modify  the install file to use the *.maps file when updating TeX's font database (modified minionpro.install).
I hope this helps to solve problems related to other TeX fonts as well.
