Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I run an Ubuntu test server, and my deployment system is also Ubuntu.

I've recently been trying to get ASP.NET to work on my test server so that we can take it live. I managed to get it installed, and configured properly, and my application is installed and running, but I can't get anything to work.

The error I keep receiving is below, if anyone has any clue what might be going on, it would be greatly appreciated.

Server Error in '/' Application

Standard output has not been redirected or process has not been started.

Description: HTTP 500. Error processing request.

Stack Trace:

Version information: Mono Version: 2.0.50727.42; ASP.NET Version: 2.0.50727.42

Apache version String: Apache/2.2.11 (Ubuntu) mod_mono/2.0 PHP/5.2.6-3ubuntu4.2 with Suhosin-Patch Server at dev Port 80

PS: I had to add three DLL's to the /bin directory in my application, copying them from Windows because I couldn't find them in any of Mono's packages. This might or might not be causing problems, I don't know. The list that I had to add is:

  • System.Web.Abstractions
  • System.Web.Routing
  • System.Web.Mvc

This helped me, YMMV. Another suggestion was to install the mono-devel package.

From here:

Try:

sudo find /usr/bin | grep gmcs

If result is NOT

/usr/bin/gmcs
/usr/bin/gmcs2

Then try:

  1. install mono-gmcs package (if only have “/usr/bin/gmcs”)
  2. in case you have only “/usr/bin/gmcs2″ make symlink on it named gmcs

    sudo ln -s /usr/bin/gmcs2 /usr/bin/gmcs

Restart apache2 or xsp or your web server and check result in browser. I think it would help.

Why not try sudo find /usr/bin -name 'gmcs*' instead? –  dlamblin Oct 23 '09 at 8:26
    
Let's not argue semantics. And I didn't write it, I'm simply providing information someone else came up with. –  Matthew Scharley Oct 23 '09 at 11:58
    
Even better question, why sudo? /usr/bin will pretty much always be world readable. –  EvilRyry Dec 8 '09 at 2:12

I setup my asp.net site blogengine.net (blog.extriko.com) on mono. I had troubles getting it to run in apache, so I found this post using mono-fastcgi-server2 and set it up with fastcgi running on lighttpd. Works great and lighttpd is super easy to setup.
