Thanks for the answers so far!
Yeah, it's a bizarre idea. But fact is that I need to perform an
operation using OpenOffice.org, and even if you run with the
"-invisible" parameter, it still requires that you have a Xserver,
which in my humble opinion, is a lame idea. The script will run a
macro on the command line, and bail out right after.
I've set the display variable to point to my xserver's IP address. You
can even specify it as a parameter. Works fine if you run it through
the shell. I disabled my Xserver's access controls just to make sure
I'm getting it right, and when I run the script, I do get an error
message on my screen, saying OpenOffice could not run, and that's it.
AFAIK, there's no error logs.
So I figure I should try to run, say, Firefox through the same script
to see what happens. I tried, and Firefox didn't run. No error
messages, no logs, nothing. Just didn't run. Then I realized I was not
being able to run anything that requires X11 through it.
PHP has a memory limit parameter, in php.ini. It's value has to be
enough to fit the memory allocated in RAM for the application being
called from inside the script. As a desperate measure, I put it to
200MB allowed, to make SURE it could fit OO.org. Well, nothing
changed, so I assume that's not the point.
So that's exactly where I am now. MAYBE it's something related to the
enviroment variables. It would be odd if it is, because I tried to run
it from a clean enviroment via shell, and it worked just fine, but I'm
still considering the possibility.
Any help is appreciated.
