After many years as a LaTeX user I'm attempting to switch over to ConTeXt. I recently upgraded my operating system to Ubuntu 7.10 (on an AMD64 machine) and got the TeXLive and ConTeXt packages from the Ubuntu repositories. I tried compiling a very simple document: \starttext Hello this is \ConTeXt. \stoptext using the command: texexec simple.tex and got the following output on my terminal: TeXExec | processing document 'simple.tex' TeXExec | no ctx file found TeXExec | tex processing method: context TeXExec | TeX run 1 TeXExec | writing option file simple.top TeXExec | using randomseed 898 TeXExec | tex engine: pdftex TeXExec | tex format: cont-en This is pdfTeXk, Version 3.141592-1.40.3 (Web2C 7.5.6) %$-line parsing enabled. (/usr/share/texmf/web2c/natural.tcx) ---! cont-en.fmt was written by pdfetex (Fatal format file error; I'm stymied) TeXExec | runtime: 0.177424 Clearly something is not working properly and I suspect the incompatibility between This is pdfTeXk... and ---! cont-en.fmt was written by pdfetex is the source of all trouble here. Could someone please point me in the right direction to resolve this? Thanks in advance, Ernesto
