# Could not map source abbreviation for ecrm1095 [closed]

I'm trying to compile a document with xelatex. On one debian machine, all goes fine and without error. On my new computer (also running debian), compiling the document fails and produces a string of errors which I don't really understand.

The first error is in the subject of this question. BTW, what's ecrm1095 (I guess the 'rm' part is 'roman').

Here's the fatal error:

kpathsea: Running mktexmf ecrm1095
! I can't find file ecrm1095'.

Any suggestions to fix?

Here's the header of the document:

\documentclass[11pt,twoside]{uwthesis}
\usepackage[T1]{fontenc}
\usepackage{fontspec}
\setromanfont[Mapping=tex-text]{Charis SIL}
\usepackage[normalem]{ulem}
\usepackage{lingmacros,avm,apacite,amsmath,array}
\usepackage{pstricks,pst-node,rtrees}
\usepackage{graphicx}
\usepackage{rotating}
\begin{document}
`

Any ideas from the experts?

I don't think you want to use fontspec and fontenc at the same time, the T1 fontenc is trying to make some bitmap ec fonts which you almost certainly don't want. Just lose the usepackge[T1]{fontenc} line. – David Carlisle Dec 4 '12 at 21:48
the ec fonts were originally designed in metafont to extend the original computer modern TeX fonts to the 8 bit T1 font encoding for TeX3. ecrm1095 is the 11 (or rather 10.95) pt version of the ec roman font. – David Carlisle Dec 4 '12 at 21:56
Okay, I believe I've got the error above solved on my second machine. I needed to install the 'texlive-latex-recommended' package (as detailed here). @DavidCarlisle: thanks for the tip about fontenc and fontspec and for the info about ec fonts! – apexofservice Dec 4 '12 at 22:15
If the problem is solved may we close the question (as too localised) ? – David Carlisle Dec 4 '12 at 22:22
