XCode clang failed with exit code 254 - ios

Question

Im Trying to build/run a iOS app on the iPhone 6.1 Simulator, however im getting this error.
Ive looked around and tried evertything ive found but nothing has helped.
This will build on other computers, but not this one.
Im completley new to iOS development so I dont know where to start.
Any help is apreciated, here is the error message:

Answer 1

I've experienced the same issue. It turned out that the host's folders shared by VMWare were read-only (even though that the read-only attribute from VM settings was unchecked).
Have you tried running sample xcode projects or copying code you're referencing to the VM?
I ended up sharing my folders using regular file sharing built in Windows 8.

Answer 2

I got the same error. I was running my Example project keeping it in VMWare Shared Folder's sub folder. And that was the reason, which made the above issue.
I copied my example project which I wanted to compile and Run (or even build which gave the above error) and pasted it into the Mac OS X(Mavericks) Desktop which was running on the VMWare Workstation 9.0. Then tried running it and it worked!
Hope this answer would be helpful to someone else out there!
Good Luck!!!

Answer 3

You made clang (the compiler) segfault (Segmentation fault: 11). Nothing you can do about it (unless you want to patch clang), you could however investigate the issue by passing the -v option when compiling.
I'm not absolutely sure, but I would say it is because your are developing inside a virtual machine. As far as I know OS X is only supported as a guest OS in VMWare Fusion 5+, and even then it is rather unstable.

Answer 4

I had this same problem with OS X, not iOS, so it seems not platform dependent.
Specifically, the compiler did not create the .o file and did not report any syntax errors.
The problem was caused by a property with a void type:
#property(readonly) void reset;
Removing the property fixed the problem.

Answer 5

This creates a similar problem, and shows a possible cause. Try putting this into a .m file and compiling it:
typedef struct{
int workAroundAsStructCannotBeOtherwiseEmpty;
float points [];
} arrayOfFloats;
#property arrayOfFloats someArrayOfFloats;
Interestingly, won't compile without the "workaround" line. If you change it to float points [10] it compiles fine.
