Question

I downloaded a few source codes containing C# code that uses windows forms. Is it possible to compile the codes under the Linux environment (Ubuntu 12.04) and run it?

I already tried successfully to compile a few C# source codes with mcs and run the resulting exe file with mono.

The source codes can be downloaded here. If it’s possible please describe how would you compile and run chapter 2/OpeningDocument solution.

$ mcs Program.cs 
Program.cs(3,14): error CS0234: The type or namespace name `Windows' does not exist in the namespace `System'. Are you missing an assembly reference?
Compilation failed: 1 error(s), 0 warnings

EDIT

$ gmcs -pkg:dotnet Program.cs 
Program.cs(17,33): error CS0246: The type or namespace name `Form1' could not be found. Are you missing a using directive or an assembly reference?
Program.cs(17,25): error CS1502: The best overloaded method match for `System.Windows.Forms.Application.Run(System.Windows.Forms.Form)' has some invalid arguments
/usr/lib/mono/gac/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll (Location of the symbol related to previous error)
Program.cs(17,25): error CS1503: Argument `#1' cannot convert `object' expression to type `System.Windows.Forms.Form'

Answer 1

If you’re not using the latest version of Mono, this should work:

gmcs -pkg:dotnet *.cs

The latest version of mono uses mcs instead of gmcs. In the previous ones, mcs targets .NET 1.1.
