Compile Errors Under OS X

Submitted by RyanA on November 5, 2007 - 3:08pm.

I made a sample program, and I tried to compile it with:

mcs Test.cs -r:Tao.Sdl.dll -r:Tao.OpenGl.dll

I then get this verbose output and I am not sure what it all means. Does anyone have any ideas?

** (/Library/Frameworks/Mono.framework/Versions/1.2.5.1/lib/mono/1.0/mcs.exe:147): WARNING **: The class System.Collections.Generic.Dictionary`2 could not be loaded, used in mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

And just some random information that may help:

  • I'm running OS X 10.5 Leopard
  • It's an Intel Mac
  • I installed the latest stable Mono from the website
  • I downloaded the latest Tao zip from the website and am using the Dll's already created for me (the ones under /bin/assemblies/)
  • My Test project's folder contains Test.cs, Tao.OpenGl.dll, Tao.OpenGl.xml, Tao.Sdl.dll, and Tao.Sdl.xml

Thanks for your help!

You should use gmcs (Mono's

You should use gmcs (Mono's .NET 2.0 compiler) instead of mcs (the .NET 1.0 compiler).

Thanks for the advice,

Thanks for the advice, SeaEagle1!

To get it to work, I also had to add this:

[dllmap dll="opengl32.dll" target="/System/Library/Frameworks/OpenGL.framework/OpenGL" /]
[dllmap dll="SDL.dll" target="/Library/Frameworks/SDL.framework/SDL" /]

(replace all [ ]'s with greater than and less than signs. The forum software removed them.)
to /Library/Frameworks/Mono.framework/Versions/Current/etc/mono/config

Then, I ran this:

gmcs Test.cs -addmodule:Tao.Sdl.dll,Tao.OpenGl.dll &&
macpack -r:Tao.Sdl.dll -r:Tao.OpenGl.dll -n:MyTest -a:Test.exe

to get the app bundle. Hopefully this helps someone, and thanks again SeaEagle1.

EDIT:
Does anyone know what command to use for macpack so the binary can run on machines without mono installed? Thanks again!
