[Mono-osx] [MonoDevelop] Debug embedded OSX app

Mon Dec 14 10:09:50 EST 2009

The box.net file is my project to create the 2 addins required to enable
debugging an embedded application using MD 2.2RC and Mono 2.6RC.

IMPORTANT:  For some reason only right clicking in the Solution explorer and
selecting Debug Item works.  I did not even attempt to investigate this.  In
other words the menu items Run | Debug and Run | Run do not work.  And right
clicking in the solution explorer and selecting Run Item does not work
either.

You must edit EmbeddedSoftDebuggerSession.cs and change this line:
var psi = new ProcessStartInfo ("open", "<full path to your>.app")

Then build both projects.  Then from the command line go into the repos
directory and type:
./clean
./docopy

This will create a MD addin repository in the directory three.

Then go to MD and click Tools | Addin Manager.  Click Repositories.  Click
Add.  Check Register a local repository.  Select the directory three.  Click
Install Addins.  At this point you should have two options.  Debugging and
Embedded.  Install both.  Restart MD.

Create a new project and select EmbeddedProject.  You can change this to be
a DLL or EXE based on how you are embedding.

You can modify an existing project (at least this worked for me) to be an
EmbeddedProject by editing the csproj file directly.  Add this line after
the <ProjectGuid> entry:

 <ProjectTypeGuids>{84408980-E7F5-11DE-B313-B87456D89593};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>

Best of luck!
