You should test for the return value of fopen. Maybe the problem was there.

I don't know the following may help or not, but in an old code I had the
filename also as the last argument of gl2psBeginPage{...char *filename; File *fp
= fopen(filename,"w");...;gl2psBeginPage(...,filename);...}. I can't remember
why I did that.
