"mod_mono and xsp have different versions" error

  • 772

I'm trying to start a test MVC4 application on Mono 2.10

$ xsp --version
xsp2.exe 2.10.2.0
Copyright (C) 2002-2011 Novell, Inc.
Minimalistic web server for testing System.Web

$ mod-mono-server4 --version  
mod-mono-server4.exe 2.10.2.0
(c) (c) 2002-2011 Novell, Inc.
Mod_mono backend for XSP

When I start mod-mono-server4 and perform a request I get this

$ mod-mono-server4 --port 8080
mod-mono-server4
mod-mono-server4
Listening on port: 8080
Listening on address: 0.0.0.0

I have read that it could be due to a version conflict between xsp and apache2-mod_mono packages, but I reinstalled them from the Novell's official repository, forcing reinstallation from YaST, and then rebooted. The error persists.

How can I fix this problem?

  1. If I recall correctly this was a bug in mod_mono or xsp (can't remember which). I suggest you move to a more recent version of mono, xsp and mod_mono in the 2.10.* series. If in any doubt you can compile from source. I wrote a mono installer script (for Ubuntu) but might be of some help.
