From this question I understand that this is due to requesting microtype operations on bitmap fonts.
My problem is that the exact code I'm compiling works fine on my laptop (OS X 10.6, TexLive and packages from MacPorts), but on my new desktop at work (RHEL6) it errors out with the pdftex error in the title.
I'm writing an article for a conference, and to get the stylesheet working I had to install eco.sty to a private texmf tree, so I suspect there's something I've missed in the install procedure, but I can't see why. I've installed
eco.sty and the fd-files to
~/texmf/tex/latex/eco and the tfm and vf files to
~/texmf/fonts/vf/public/eco respectively (as the
INSTALL file told me to). And I remembered to
Is there something else I need to do, like something related to
updmap? This question would seem to indicate that this might be the culprit, but eco doesn't come with any map files, nor can I seem to find any fitting map files on my laptop.
