I seem to suddenly need erlang on IRIX and Linux. Everything
works fine on Linux, of course. But now I'm porting erlang to IRIX 6.5.
(64 bit) I will post all my changes back to this list for people to use.
For the moment however, I'm not changing things in a cross-platform
manner. I'm simply making changes so things work. (Hack and slash
method.) When I get a little better at autoconf I'll make fixes the
correct way.
1) gcc doesn't work on IRIX above 5.3. :^(
2) SGI's cc doesn't support any -W options. I had to remove them.
3) SGI's cc doesn't support -fno-inline
4) IRIX doesn't seem to support vfork. (I havn't found it yet.)
5) There are a number of compile problems with standard c
shortcuts which seem not to compile. I've added casts in
a number of places to make things work.
I've now compiled the package on the SGI. However, it seg faults
on startup. So here is the stack dump. There seem to be two problems --
the first is a memory allocation failure. The second is a seg fault in
the reporting of that error. :^)
Here is the stack trace:

As you can see, it had a problem allocating memory. (This machine
has HUGE ammounts of memory, but I haven't looked at how much has been
allocated.) This may be a problem with allocating more memory than is
available under IRIX. (Linux will allocate more memory than is available,
which can lead to problems later.)
I would love any comments or suggestions... If anyone wants the
patch files now (before things are working and before they are integrated
with the configure system) let me know.

If you say it in CAPS, it means you spent the extra energy

Well if you figure out what is needed I can get it into autoconf.

The system used to be a lot more portable, as time went by more people
started working with it and we were under pressure to produce versions
for specific OS's... So the system is a bit less portable today
unfortunately, but our aim is to fix these things as possible so it's
great to see people running it on all kinds of things!

I don't know about 6.5 (we don't have any IRIX boxes here) but Shawn
Pearce sent us this earlier:

Good luck,

gcc 2.7.2.6 will build and create o32 objects which are runnable on all Irix
versions. gcc 2.8.1 will create n32 objects, which are runnable on 6.2 and up.

Irix doesn't have vfork at all. See the patch I sent in earlier, Sebastian
said to put it in sys.conf, I actually put those lines in sys.h.

I haven't tried SGI's cc. Good thing i let it go with gcc first.

See the patch i sent in, it'll fix the core dump.
You'll need to apply the other patches I sent for the .erl files in the kernel
in order to get DNS (and thus distributed erlang) running correctly.

Okay. I'll make the patch files in a few days.

Ah! That explains things a bit. :^)

Umm... I don't seem to have a file called sys.conf. I'll see if
I can find some other file which might work as well...

Ah ha! I added your code to
sys.h in system/emulator/runtime
and to
erl_unix_sys in system/emulator/unix.sys
and it seems to work! Thanks.
