Re: GNUstep install on FreeBSD9.1

Hi David,

I think I've narrowed it down in the config log:

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

I've tried manually compiling & linking a bare bones objc program, and I get 
the same results at link time.
This is with clang v 3.2, I have libobjc2 installed and I added these options 
to /etc/make.conf

GNUSTEP_WITH_CLANG=yes
USE_GNUSTEP_CONFIGURE=yes
ADDITIONAL_CFLAGS +=-I/usr/local/include
ADDITIONAL_LDFLAGS +=-L/usr/local/lib -lobjc
CC=clang
CXX=clang++

The linking with /usr/lib/libgcc.a seems to be a default ? Is it really needed 
or can it be turned off with some linker switch ? (I haven't found any).

Cheers
Steven
