Thread: compile problem on a vax
Hello,
I have been trying to compile postgresql-7.0.3 on a uVax II running NetBSD
1.5, after some problems i am almost there, now i only get these errors
during the final compile:
>gcc -I../include -I../backend -O2 -pipe -Wall -Wmissing-prototypes -Wmissin

I have change something in /src/include/storage/s_lock.h (because else i
would get another error, saying that slock_t was already defined in os.h):

Can anybody help me and explain to me how to fix this?
Are there people here that have any postgresql version running on the vax?
which version do you use and which OS for your vax
thank you,
bart
Do a mailing list search. Someone did work on a VAX port about a year
ago. They never got it to work, though. Sounds like you have problems
with the assembly code.

I'll bet that the assembler is taking the 'r0' references in the TAS()
snippet to be a global-variable name, rather than register name as
intended. Possibly $0 or %0 or some such locution is needed.
The VAX port has evidently not been used in a long time. I had noticed
that it was inconsistent with all the other ports in defining slock_t
in s_lock.h rather than in the OS-specific header files; that's clearly
wrong now.
Feel free to submit a patch once you get it worked out.
regards, tom lane

It's been a long, long time, but I think r0 is actually a register name on VAX, dunno if it would cause a conflict, probably depends on the asm syntax. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."

I did the VAX port, and it worked, once upon a time. Now, I haven't had a NetBSD/vax system for a long time, and the surrounding code has changed. If noone else does anything about it, I probably will fix it eventually, but I can't do anything as it now stands. -tih -- The basic difference is this: hackers build things, crackers break them.

Any idea when it happened so I can fix it? -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026

OK, here is the fix:
__asm__(" movl $1, r0 \
bbssi $0, (%1), 1f \
^^
clrl r0 \
The old pgindent had a bug with numbers followed by a letter, '1f -> '1 f'.
The new version I have fixes that problem, and I verified that the VAX
ASM doesn't change under the new pgindent.
