Ii. Common Errors

1. iPhone/iPod Touch application executable is missing a required architecture at least one of the following architecture must be present armv6
Solution:

For some reason the default architecture settings with xcode 4.2 is only for armv7. go to Target-> build settings-> ubuntures-> release on value dropdown pick "other ...",

Remove $ (archs_standard_32_bit), and add 2 rows first with "armv6" and second "armv7"
Done
