How to use references when compiling c# code via command line

Question

Could anyone help me compile via command line some c# files? I have 4 files to compile, Main, Form1 (which uses 2.cs file) and another class used in the project.

I would like to compile this project in command line so I could add the /t:library switch (like in this tutorial: http://dotnetslackers.com/articles/csharp/WritingAnActiveXControlInCSharp.aspx).

However after using "csc /t:library Program1.cs MainForm.cs MainForm.Designer.cs EigenObjectRecognizer.cs" I get missing assembly reference errros such as these:

\Project\FaceRecProOVaspVer\FaceRecProOV\MainForm.cs(14,15): error CS0234: The type or namespace name 'Structure' does not exist
    in the namespace 'Emgu.CV' (are you missing an assembly reference?)

I do have installed EMGU binaries installed. I would think I need to use some .dll's from that folder like EMGU.CV.dll?

Solution

To reference a library on the command line you need to use the /r: compiler option and pass the relative path to the library. Assuming it's in the same directory you can do the following

csc /r:EMGU.CV.dll /t:library Program1.cs MainForm.cs MainForm.Designer.cs EigenObjectRecognizer.cs
