Rather than create a symlink it is best to install mono-devel to resolve this issue. Either: sudo apt-get install mono-devel or: apt://mono-devel

try
sudo find /usr/bin | grep gmcs

if result is NOT
/usr/bin/gmcs
/usr/bin/gmcs2

try
1)install mono-gmcs package (if only have “/usr/bin/gmcs”)
or
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.

Okay, the test file content in my previous commit has been crippled, here again:

<%@Page language=”vb” %>

<%
Response.Write (”Hello world”)

I got the same problem for normal aspx files on my Debian system.
I also installed the VNBC compiler with apt-get install.

A test file with this content started working:
—-SNIP—-

TEST
—-SNIP—-

I’m wondering why the C# compiler has got such problems while the VB compiler is running well?

I build a website in ASP.net that works perfectly in a windows server. I need to migrate this website to a linux server, which dont have the Mono. I’m going to suggest these application to my co-workers, but i have a doubt: do i have to change anything on my code source? Or the files i have now will just work fine?

Tks

I have the same error….

By: Gerd

Gerd — Thu, 12 Jun 2008 09:30:21 +0000

I installed Ubuntu 7.10 with PHP and mySQL and also installed mono for ubuntu (both, xsp1 and xsp2) with examples/demos.
When running xps or xps2 I seem to get the predicted responses.
However when going to http://localhost:8080/ the following is displayed in the browser in either case:

Server Error in ‘/’ Application
File ‘/’ not found.

Description: Error processing request.

Error Message: HTTP 404. System.Web.HttpException: File ‘/’ not found.

Stack Trace:

System.Web.HttpException: File ‘/’ not found.

what went wrong? Mind you, I am also quite new to Linux and ubuntu in particular and can do with all help I can get.

Cheers, Gerd

It’s working now!!! Here is the solution for Ubuntu users:

sudo cp /usr/share/asp.net2-demos/index.aspx /usr/share/asp.net2-demos/index2.aspx

I got this solution from a blogger in another site.

Hi all. First of all, thank you for this excellent tutorial. I have an asp.net 2.0 app that I used to run on IIS but I am trying t get it to work on Ubuntu with Apache. However, this app uses an MS access database and I cant put xsp to work with this. Any ideas?

To David:
– i think i’m late on posting this
You must be on the directory /usr/share/asp.net2-demos/ before you run xsp. Otherwise that error will be displayed.
Please take note this when you run xsp, you should see the Root directory: /usr/share/asp.net2-demos/
HTH.

Another option is the Neokernel, there is a release for Mono of the
Neokernel Web Server at http://www.neokernel.com, it’s easier to run ASP.NET with
the Neokernel than with XSP or apache/mod_mono.

if you install asp.net version 1 documents you should be able to see the test page

Hi,
Great sample I am using Ubuntu and this helped a lot. My issue is that when I try to run the http://localhost:8080/ I Get the following:
Server error in ‘/’ application
File ‘/’ not found.
Description: Error processing request.

Error Message: HTTP 404. File ‘/’ not found.

I also used the sudo cp /usr/share/asp.net2-demos/index.aspx /usr/share/asp.net2-demos/index2.aspx
with same results.
Any help would be appreciated

Thanks
David…….
