Re: libobjc2 compilation error - FreeBSD 10 and Raspberry Pi

[Mathias Bauer]

From my own experience using clang 3.4 on arm is no fun. I got problems 
with the generated assembler code on several occasions.

You can try to add -integrated-as to your compiler settings, but if that 
doesn't work, you should try to get a build from a recent trunk version 
or downgrade to 3.3.

Mathias
