GDL2 compilation errors

[Edwin Ancaer]

Hello

I just downloaded GDL2, and tried to compile it (I'm using Clang 3.4, and libobjc2).

I got the following compilation errors:

EOGenericRecord.m:1526:19: error: incomplete definition of type
      'struct objc_class'
  size = selfClass->instance_size;

EOGenericRecord.m:1622:26: error: incomplete definition of type
      'struct objc_class'
      size += objectClass->instance_size;

Can someone point me in the right direction?
