I did it the way you recommended, I tried to configure and compile the
version 3.4.3 of gcc.

----
CC=gcc ../configure --prefix=/opt/apps/gcc-3.4.3 --with-gnu-as
--enable-languages=c++,java  --enable-libgcj 
--enable-version-specific-runtime-libs

Parallel to the gcc-3.4.3 i tried to compile 3.2 with this configure:

----

CC=gcc ../configure --prefix=/opt/apps/gcc-3.2 --with-gnu-as --enable-libgcj
 --enable-version-specific-runtime-libs --without-libffi


No errors while "configure" and that error while "make bootstrap":

You talked about gcj should run without libffi. But how do i have to compile
the gcc, that gcj will work?

I'm new in HP-UX. It would be nice if you could explain me, what I exactly
did wrong. And how I have to do it to bring it to work...

Thanks a lot
Corsin
