Problem compiling libobjc2 on pcbsd 9.1

[Stephen Woolerton]

Hi everyone,

I'm hoping someone can help me to compile gnustep-base on PCBSD 9.1. 

Notes:

 - I'm compiling gnustep-base rather than using ports, in order to use blocks. 

 - Am using a fresh "jail" made with PCBSD's "warden" and latest ports tree. 

 - using clang 3.1

 - On compiling libobjc2, I get an error which is reproduced below.

A question...  I know this isn't a *BSD list, but am wondering, if someone can advise how to compile with a version of clang installed via ports. PCBSD 9.1 ships with clang 3.1 and I've installed clang 3.2 via ports. How do I access clang 3.2 to compile code?

I have followed the process below:-

cd /usr/local/src

svn co svn://svn.gna.org/svn/gnustep/modules/ gnustep

export CC=clang 
clang -v
cd gnustep/core/make
./configure --enable-debug-by-default --with-layout=gnustep

gmake  

gmake install
. /usr/GNUstep/System/Library/Makefiles/GNUstep.sh

# - Build libobjc2
cd ../../dev-libs/libobjc2

mkdir Build

cd Build

cmake .. -DCMAKE C COMPILER=clang -DCMAKE CXX COMPILER=clang++

------------------------

The output I get is.......
