Trying to run a mono bundled program, but getting missing libgdiplus exception

I am currently trying to get my C# program to run on Linux. Using mono on my Linux machine, the program runs fine. So I used mkbundle and it all compiled and such correctly. But when I try to run the bundled program on any other Linux machine I get this error:

Unhandled Exception: System.TypeInitializationException: An exception was thrown by the 
type initializer for System.Windows.Forms.XplatUI ---> 
System.TypeInitializationException: An exception was thrown by the type initializer for 
System.Drawing.GDIPlus ---> System.DllNotFoundException: libgdiplus.so.0

This is the mkbundle command I used: 

mkbundle --static program.exe --deps -o a.out

I also tried using mkbundle2 with no luck.

I thought maybe there was a way to specifically include libraries with mkbundle (like telling where to find libgdiplus). It should be linked in when I use mkbundle, but I guess it isn't because when I run my program on any other Linux machine (that isn't running mono), I get this error.

Both machines are running Ubuntu 10.10 AMD64.

The mono 3.0 config file for windos has bad entries dor the libgdiplus references.

Change the two lines of the file C:\Program Files (x86)\Mono-3.0.2\etc\mono\config as follows:

 <dllmap dll="gdiplus" target="/tmp/install/lib/libgdiplus.so" os="!windows"/>
 <dllmap dll="gdiplus.dll" target="/tmp/install/lib/libgdiplus.so" os="!windows"/>

If on your "foreign" machine you run this:

ldd a.out

You should be able to see what shared libraries it is expecting. You may need to distribute libgdiplus.so with your program or perhaps statically link in libgdiplus.a

Extrernal helper libraries are not bundled in the executable, so you will either need to distribute libgdiplus as well, or use the -oo option to create an object file that you will link in a program together with the libs that you need. Of course you will also have to add a dllmap entry to map from, for example, libgdiplus to __Internal.

Note that if you just distribute the program generated by mkbundle as is, you're violating mono's free software licence, so unless, for example, you have a special licence from Novell, or you program is free software or you also distribute the object files of the app so people can relink themselves, you shouldn't use mkbundle.
