1.10) How do I install PostgreSQL V6.3 under Irix 6.x?
|
||||
|
||||
Irix 6.2-6.4 has a bug in ld which mishandles the addresses of
|
||||
static procedures when object files are assembled into
|
||||
larger object files using 'ld -r'. This bug has been reported
|
||||
to Silicon Graphics.
|
||||
|
||||
Depending on your Irix installation you may also encounter
|
||||
2 other problems detailed below: Conflict in C standards,
|
||||
Conflict in library functions.
|
||||
|
||||
a) Solving the ld bug
|
||||
---------------------
|
||||
|
||||
One option is to use the Gnu version of ld. Alternatively,
|
||||
the following patch should be applied as a workaround.
|
||||
(Supplied by Bob Bruccoleri <bruc@bms.com> and modified for
|
||||
PostgreSQL V6.3 by Lasse Hiller Petersen <lassehp@imv.aau.dk>)
|
||||
|
||||
Apply the following patch:

Lasse configured with ./configure --enable-locale
|
||||
and modified Makefile.custom to contain:
|
||||
CC = cc -n32
|
||||
LD = ld -n32
|
||||
|
||||
He reports that the installation without -n32 works fine too,
|
||||
but the -n32 was required for compatibility with his Perl
|
||||
installation. His system was an Origin200 running IRIX64 v6.4.
|
||||
|
||||
|
||||
b) Conflict in C standards
|
||||
--------------------------
|
||||
|
||||
I have found that the following patch is also necessary in order
|
||||
to prevent a duplicate definition of a Union used for semaphores.
|
||||
Apply the following patch to:
|
||||
.../src/makefile/Makefile.irix5:
|
||||
|
||||
*** src/makefiles/Makefile.irix5.orig Thu Mar 5 16:59:58 1998

$(LD) -G -Bdynamic -shared -o $@ $<
|

|

! CFLAGS+= -U_NO_XOPEN4
|
||||
|
||||
i.e. the addition of the line:
|
||||
CFLAGS+= -U_NO_XOPEN4
|
||||
|
||||
This is needed to stop the semun union being redefined in
|
||||
/usr/include/sys/sem.h
|
||||
|
||||
c) Conflict in library functions
|
||||
--------------------------------
|
||||
|
||||
In addition, if you have the nsl and crypt libraries these will
|
||||
conflict with the required definitions. I think that libnsl.a
|
||||
may be the Netware socket library (or something similar). In
|
||||
any case, if you have these libraries, they will be added to
|
||||
Makefile.global and you will need to remove them.
|
||||
|
||||
Thus, you should edit .../src/Makefile.global. Goto (approximately)
|
||||
line 217 where LDFLAGS= is set and remove -lnsl and -lcrypt
|
||||
from this line.
