Expected function body after function declarator error

Question

I downloaded the class files and demo program here: http://github.com/matej/MBProgressHUD

When I try to compile the program, I get several errors. The first one appears here:

CG_EXTERN void CGPDFContextAddDocumentMetadata(CGContextRef context,
  CFDataRef metadata) CG_AVAILABLE_STARTING(__MAC_10_7, __IPHONE_4_0);

On the second line the error is "Expected function body after function declarator."

What's wrong with this code? How can it be fixed?

Answer 1

In the project build settings, change the compiler version to the system default.
