i use gcc-3.0 (release, without separate libobjc)
GNUstep worked with gcc-2.95.3 and pgcc-2.95.2 one week ago
(with libobjc)

already done that.
./compile-all / (I'm using /, not /usr/GNUstep)

I'm allways doing this :)

I think the main problem is that gcc-3.0 is somewhat broken for me.
e.g. ./configure in core/make tells me that that objc has no thread
support (but if I copy libobjc* from gcc-lib/ to /lib, it finds
thread support. Moreover gcc-3.0 uses a wrong path to mkinstalldirs,
so make install for gcc fails. After fixing it, it installed smoothly).
Compiling a simple objc app (not GNUstep) works.

bash-2.04# gcc -v 
Reading specs from /bin/../lib/gcc-lib/i686-pc-linux-gnu/3.0/specs
Configured with: ./configure --prefix=/soft/gcc-3.0 --enable-shared
--enable-threads=posix --enable-libgcj --enable-nls
Thread model: posix
gcc version 3.0
 
BTW, i'm using glibc-2.2 (I have problems with glibc-2.2.3, because
glibc-2.2.3 pthread support is broken on my system)

i think it just a problem with my system/configuration.
I'm using autoconf-2.50, automake-1.4d, binutils-2.10.1 and
make-3.79.1. I will recompile gcc-3.0 and try again ...
if this doesn't work, I will send a bug report!
