I was so excited to see MonoTouch released two days ago. congratulation to Miguel and the team at Novell! I picked up my MacBook Pro where I have been building IPhone apps using XCode (Objective C :( Ah! Karamba!), and installed Mono, MonoDevelop and MonoTouch as soon as I received it from Miguel (Thanks Miguel!).
Well, MonoDevelop started jumping up and down on my dock for few minutes but never started. Looked at the log files and it seemed like a permission issue with the ~/.WAPI directory. I am not really a MAC person, so went to Google for rescue, no mention of this. Sent an email to Miguel De Icaza (Mr. Mono himself) and he put me in touch with Michael Hutchinson and BAM!, Mike is Da Man!
If you see this problem on your machine, what probably happened is that you never ran any MONO programs on your MAC before installing and running MonoTouch, MonoDevelop. If that is the case, launch a Terminal window and type the following two command:
| killall monodevelop mono mdtool rm –rf ~/.wapi Have fun developing for the IPhone in C# |
