7.1.3, IRIX 6.5 and gcc

I am trying to get 7.1.3 to compile on IRIX 6.5.13 using GCC 3.0.1 ... I
always end up having this error:

gcc -Wall -Wmissing-prototypes -Wmissing-declarations

Go into the file src/backend/storage/s_lock.c and change the line that
looks like

#if defined(__mips__)

to

#if defined(__mips__) && !defined(__sgi)

(This "mips" assembly code is there for the likes of NetBSD and Linux.)

This should allow for the compilation to continue.

I read in the archives that GCC was not very good to compile on IRIX, at
this stage I have no choice, we don't have MIPSPro licensed.

"not very good" can also be read as "won't work", unless GCC 3 now does
better.

Hello

Thanks Peter! That solved the problem and I could get postgresql 7.1.3 to
compile. Actually it works :) It seems that for my needs now, this GCC is
enough... At least I could compile postgresql, python, postfix and xemacs
and some other GNU software ... :)

Thanks again!

Okay, the fix has been checked in for the next release.

I'm referring to the note at http://freeware.sgi.com/howto.html:

* gcc vs. cc

Code that runs fine when compiled with SGI cc
and doesn't run when compiled with gcc might be
calling one of the following functions:

inet_ntoa, inet_lnaof, inet_netof, inet_makeaddr, semctl

(there may be others). These are functions
that get passed or return structs that are smaller than 16
bytes but not 8 bytes long. gcc and SGI cc
are incompatible in the way they pass these structs so
compiling with gcc and linking with the SGI
libc.so (which was compiled with the SGI cc) is likely to
cause these problems. Note that this problem
is pretty rare since such functions are not widely used.
This may be considered a bug in gcc but is too involved to fix I'm told.

PostgreSQL calls at least semctl(), but not necessarily during mere
"seeing if it works". So be careful.

Check out the above site for more resources about open source software on
Irix.

I have complied binaries for IRIX 6.5.12 using MIPSPro. I'd be happy
to send them to anyone that wants them or upload them to the website
if someone tells me where to place them.
