How to reference these packages with Mono in order to compile

Question

I'm trying to compile a C# script with Mono on Debian by command line, like this:

gmcs Main.cs 

However, I get the following error:

Main.cs(6,14): error CS0234: The type or namespace name `Drawing' does not exist in the namespace `System'. Are you missing an assembly reference? Main.cs(7,14): error CS0234: The type or namespace name `Drawing' does not exist in the namespace `System'. Are you missing an assembly reference? Main.cs(12,7): error CS0246: The type or namespace name `iTextSharp' could not be found. Are you missing a using directive or an assembly reference? Main.cs(13,7): error CS0246: The type or namespace name `iTextSharp' could not be found. Are you missing a using directive or an assembly reference? Main.cs(1526,31): error CS0246: The type or namespace name `Bitmap' could not be found. Are you missing a using directive or an assembly reference? Main.cs(6,14): error CS0234: The type or namespace name `Drawing' does not exist in the namespace `System'. Are you missing an assembly reference? Main.cs(7,14): error CS0234: The type or namespace name `Drawing' does not exist in the namespace `System'. Are you missing an assembly reference? Main.cs(12,7): error CS0246: The type or namespace name `iTextSharp' could not be found. Are you missing a using directive or an assembly reference? Main.cs(13,7): error CS0246: The type or namespace name `iTextSharp' could not be found. Are you missing a using directive or an assembly reference? Compilation failed: 9 error(s), 1 warnings 

These the references at the top of Main.cs:

using System; using System.IO; using System.Collections.Generic; using System.ComponentModel; using System.Diagnostics; using System.Drawing; using System.Drawing.Imaging; using System.Net; using System.Text; using System.Text.RegularExpressions; using System.Xml; using iTextSharp.text; using iTextSharp.text.pdf; 

I understand that I have to tell Mono which libraries to include by adding -pkg:whatever. My problem is that I do not know what these libraries are called, so I don't know what command is used to include them. Actually, I don't even know whether I have to download these libraries from somewhere or whether they come with Mono.

Note also that the last 2 are the iTextSharp library, for which I have itextsharp.dll just placed in the same directory as the script, since I don't know what else to do with it.

Please could someone explain to me how to get the file to compile!

Answer 1

Try this:

gmcs /reference:System.Drawing.dll /reference:itextsharp.dll Main.cs 

With newer versions of mono, try this.

mcs /reference:System.Drawing.dll /reference:itextsharp.dll Main.cs
