gcc on/for HPUX

[Vermeulen Jan <Jan dot Vermeulen at siemens dot atea dot be>]

Hello there,

I have a small problem that i can't seem to solve.
We have a HPUX machine and we would like to port the wonderful GCC to this
machine, because it can optimise C/C++ much better than the native compiler
can.

The system we use is a HP 9000 712/80 (pa-risc1.1, if i'm not mistaken) with
HP UX 10.20P.
And i would like to make the gcc on my Intel linux machine, so i only have
to transfer the binaries to the HPUX machine.

I know this is not the easiest way, because i have to make a crosscompiler
that outputs code for the hp9k712 and then recompile the gcc-source with
this crosscompiler to get the binaries. (i think this is called canadian
cross, right?)

It would also be nice if i could just make binaries for hp9k712 on my linux
machine and then just transfer the executables to be run on the target.
(would only involve making the crosscompiler for hpux)

Now on with the problem :

when i do "configure ....." it starts already with displaying an error
message "ld not supported with this configuration (other directories should
be fine)". 
I guess this is because the linker is sort of property of HP and they did
not grant permission for other compilers to make binaries for their
machines. (please correct me if i am wrong. I am simply guessing here).

I thought "no problem, i just make the object files on my linux pc and then
link them on the hp." (i hope this is possible), but then the following
error appeared:

/home/jan/src/hpbinutils> ../binutils-2.9.5.0.24/configure --target=hp9k712

configuration not supported in following directories:
"ld"
(other directories should be fine)

/home/jan/src/hpbinutils> make

gcc -g -O2 -W -Wall -o size size.o bucomm.o version.o filemode.o

/home/jan/src/hpbinutils/bfd/../../binutils-2.9.5.0.24/bfd/targets.c:955:

collect2: ld returned 1 exit status

What do you think i am doing wrong ?

i made a m68k crossgcc successfully, following the steps described here:
http://sources.redhat.com/ml/crossgcc/2000-q2/msg00195.html

i am now trying to follow the same steps to make the hpux crossgcc.

Thanks in advance for any help.
Jan
