What version of Xcode for MacOS 10.6.8

Thanks.

It doesn't look like error, I agree. But the *.app generated won't execute no matter which of the below line I use.

open myprogram.app
open -a myprogram

Even when I use it with "sudo" or do "chmod 0775 myprogram.app" it still won't execute
The error message is this:

LSOpenURLsWithRole() failed with error -10810 for the file
/Users/mymac/Desktop/myprogram/myprogram.app.

What does it mean, why doesn't it run (I know the code is good)?
Thanks for help!

Can you navigate in the terminal into myprogram.app/Contents/MacOS and run myprogram?
What will you get in the terminal after running?
