Re: [PyX-user] Permission issues with temporary files when scripting through Apache

[André W. <wo...@us...>]

Hi William,

we need to work around the problem that PyX originally uses tmp files at the local directory. (We did this as non-local file processing by TeX/LaTeX failed in earlier TeX/LaTeX distributions. Today, you can also commonly use output_dir and jobname command line flags, which were not present 10 years ago when we designed the TeX interface.)

I guess (and hope) the enclosed version works on your platform. It does a non-local file creation in a temporary directory. You should do that directory and texrunner setup for each request where you want to do use PyX to generate some output.

Best,


André
