libobjcxx

[Kal Conley]

Hi Folks,
I am having linking issues trying to compile an objective-c++ source
file that uses exceptions. In particular, I get the following link error:

(.data.__objc_eh_typeinfo_NSException[__objc_eh_typeinfo_NSException]+0x0):
undefined reference to `vtable for gnustep::libobjc::__objc_class_type_info'

I think I need to link to libobjcxx in addition to libobjc but I am not
sure how I can get GNUstep build system to build it automatically. I am
on debian and I am using the following commands to build GNUstep from
source:

#----------------------------
PREFIX=/opt/local/GNUstep
mkdir -p "${PREFIX}"

export CC=clang
export CXX=clang++

cd gnustep

cd core/make
./configure --enable-debug-by-default --with-layout=gnustep
--prefix="${PREFIX}"
make && sudo -E make install
. "${PREFIX}/System/Library/Makefiles/GNUstep.sh"

cd ../../dev-libs/libobjc2
make debug=no && sudo -E make strip=yes install

cd ../../core/make
./configure --enable-debug-by-default --with-layout=gnustep
--prefix="${PREFIX}"
make && sudo -E make install

. "${PREFIX}/System/Library/Makefiles/GNUstep.sh"

cd ../base
./configure --with-ffi-include=/usr/include/`gcc -dumpmachine`
--prefix="${PREFIX}"
make -j 3 && sudo -E make install
#----------------------------

This automatically builds libobjc.so in addition to libgnustep-base.so
in /opt/local/GNUstep/Local/Library/Libraries/.

I would like to have libobjcxx.so build and installed there too. What is
the easiest way I can achieve this? Or am I way off base?

Thanks!
Kal
