I am trying to run a LaTeX parser from a dokuwiki website. The LaTeX parser relies on the mimetex cgi module, it is executed from a PhP script using the following command:
shell_exec('/var/www/cgi-bin/mimetex.cgi -f /var/www/html/test1.tex -e /var/www/html/test1.gif');
However, the command is not properly executed when running the PhP script. I ran a test command such as:
shell_exec('cp test1.tex test2.tex');
and was able to check that the file test2.tex was indeed created. I also ran the command:
/var/www/cgi-bin/mimetex.cgi -f /var/www/html/test1.tex -e /var/www/html/test1.gif
from a terminal, and it was executed without error. I also made sure that my apache server is configured so that it can execute cgi scripts following https://www.ionos.com/community/server-cloud-infrastructure/apache/enable-cgi-scripts-on-apache/
I am missing something here... but I don't see what...
