mod_perl IPC::RUN Windows problem

jonb has asked for the wisdom of the Perl Monks concerning the following question:

Hi I am running Windows2000 with Apache 2.2 with mod_perl and I am trying to get GraphViz to work. (perl-graphviz) The thing works perfectly in batch(command mode if you will) but when running on the web, dot.exe hangs and never returns. dot.exe comes with Graphviz, and graphviz.pm starts it up via IPC::run. Is anyone at the monistary familiar with this ? I have graphviz working with PHP on the web so there is I think no problem with dot.exe. Anyone ? Please dont say stick to PHP.....

I'm assuming you mean that the problem is not universal rather then that I should stick to PHP. Thats great, it means there is a solution..... But I'm not sure how to proceed in finding it, any suggestions ?	[reply]

Hi :) Re: Trying to use IPC::Run under mod_perl (2) should help. Basically mod_perl restricts access to the underlying os. Jason L. Froebe Help find a cure for breast cancer!

You may be having Windows-specific issues here. I think IPC::Run assumes that forking works in a Unix-like fashion. The best place to get help is the mod_perl mailing list, where we have a couple of pretty knowledgeable users who run on Win32. More info at http://perl.apache.org/.	[reply]
