This is clearly nonsense - it seems to not be linking to libc either...

GCC is version 4.2.1 20070831 , and /usr/lib/libgcc_s.so exists.
Can you show me the command that linked libobjc.so? (either make VERBOSE=1 or ninja -v, depending on how you are building libobjc2)


Hi David

Solved... No idea where the renegade libobjc.so in /usr/local/lib came from as it had a date of "April", while the ports jail was only a week old. I found the libobjc.so I had built, inside the GNUstep folder tree.

So I created a new jail yesterday and ran through the install process again, and now have gnustep-base working with blocks and libdispatch.

Thank you for your assistance. Much appreciated.

And in case it will help anyone, here is the recipe I used on PCBSD 9.1...

Create a new jail in PCBSD 9.1, include ports

portsnap fetch update
#vipw  ->
#  make /usr/local/bin/bash the shell of the "toor" account
#  add new account "devel" also with bash shell
#passwd toor -> set root passwd
#su - toor   	# need to install sudo...

pgk_add -r vim bash portmaster subversion libdispatch
cd /usr/ports

portmaster /usr/ports/lang/clang33

# gnustep sources
mkdir /usr/local/src
svn co svn://svn.gna.org/svn/gnustep/modules/ gnustep
