[parisc-linux] octave2.1_2.1.35-6_hppa

[HEISERER DANIEL]

Hi,
a buddy pointed me to the debian build archive,
because I had problems building a 64-bit octave executable
on AP-RISC-2 HP-UX-11.11.
I used the gcc-3.0.2 which was a 
 /usr/local/bin/gcc:     ELF-64 executable object file - PA-RISC 2.0
(LP64)
and it also produced such code. Unfortunately the octave builds,
but fails immediately by trivial operations.
I am also a little be astonished about the different object files
existing
on PA-Risc. There are 
/usr/local/bin/perl:    PA-RISC1.1 shared executable dynamically linked
-not stripped
as well as "PA-RISC2" executables.
Honestly I have no idea what the difference between ELF-64 and PA-RISC-2
is.
Are both 64 bit.

Finally I found the debian archive for octave. So my question is:

Do you build this octave for 
o linux on PA-Risc or also for
o HP-UX-11.11 ????

Is it finally 64 bit? and how did you build it.

I would appreciate any comments to my open questions.

thanks, daniel

Unfortunately, we don't support 64-bit userspace on PA/Linux yet.

No.  PA-RISC 2.0 introduced some new instructions, but does not have to be
64-bit.  64-bit can be useful, but it can also slow down applications.  So
it's a tradeoff.

We don't build binaries for HP-UX.  Some people have suggested starting a
new port to build binaries for proprietary unices sch as Solaris and HP-UX,
but nobody has actually done so yet.

It may be helpful, though, to pick up the Debian source package and look
over the patches since there may be some that work around the "gotchas" of
the platform.  It would at least be a good start, even though the patches 
are probably a bit more linux-specific and probably shouldn't be used
verbatim hoping that they fix problems for HP-UX compilation.

Also note that "PA-RISC1.1" on HPUX implies the binary is a SOM binary
(not ELF). parisc-linux uses ELF-32 format by default.  This was "invented"
for the parisc-linux port.

parisc-linux kernel has support for SOM binaries but it's really only
for HPUX application compatibility.

Since PARISC2.0 introduced 64-bit capability, many people equate the two.
(that's not a shooting offense. ;^) While Matthew is correct, in practice
most folks build PA1.1 binaries when they want a 32-bit application.

I was building 32-bit PA-RISC2.0 linux kernels. But the toolchain was using
"reloc" (type 74, iirc) that the kernel dynamic linker couldn't grok.
So I couldn't load any kernel driver modules.  I decided it wasn't worth
pursueing and now build PA 1.1 kernels.

PA-RISC-2 describes the machine architecture.  ELF-64 describes one of the
object file format that is use on PA-RISC-2 machines.  The SOM object
file format is used for 32-bit objects.  As Grant noted, SOM objects
support architectures from PA-RISC 1.0 onward.  However, a 2.0 object
will not work on a 1.1 machine.

The object file format zoo is even worse than described above.  The debug
formats used by gcc differ from those used by HP compilers.
