I have an ios xcode project, that compile and running fine for simulator but failed to compile for device target.
I am trying to port a QT project to iOS and my project setup is quite complex. The desktop version is totally working fine and I didn’t change any code except removed all UI related code.
I already file a bug report to apple (problem id:12103227) but just wondering anyone seen similar problem before?
I am using Xcode 4.4.1(4F1003) and Apple LLVM compiler 4.0

It turns out that the header file Qt used for atomic variable linked to ppc header instead of armv7. The ppc header contains some inline assembly code and crashed the cross compiler.
