+
+ If gmake fails in .../src/backend while building obj/ACCESS.o

+From: bruc@bms.com (Robert Bruccoleri)
+Subject: [PORTS] Patches for Irix 6.4
+
+I have worked out how to compile PostgreSQL on Irix 6.4 using the -n32 compiler
+mode and version 7.1 of the C compiler. (The n32 compiler use 32 bits addressin
+g,
+but allows access to all the instructions in the MIPS4 instruction set.)
+There were several problems:
+
+1) The ld command is not referenced as a macro in all the Makefiles. On
+this platform, you have to include -n32 on all the ld commands. Makefiles
+were changed as needed.
+
+2) There is a bug in "ld" which mishandles the addresses of static procedures
+when object files are assembled into larger object files using "ld -r".
+Because of this, I put a hack into src/backend/Makefile to avoid all the
+SUBSYS.o files and just link all the objects. I have contacted SGI about the
+problem, and hopefully, it will be fixed in the near future.
+
+3) Lots of warnings are generated from the compiler. Since the regression
+tests worked OK, I didn't attempt to fix them. If anyone wants the compilation
+log, please let me know, and I'll email it to you.
+
+The version of postgresql was 970602. Here is Makefile.custom:
+
+CUSTOM_COPT = -O2 -n32
+MK_NO_LORDER = 1
+LD = ld -n32
+CC += -n32
+
+Here are the patches:

+1.9) Why does lex fail with PostgreSQL 6.2.1?
+
+ IRIX 5.3 lex has been reported to fail in
+ postgresql-6.2.1/src/backend/parser with the error:
+
+ lex scan.l
+ "scan.l":line 86: Error: Invalid request %x xc
+ gmake[2]: *** [scan.c] Error 1
+
+ The answer is to use GNU flex 2.5.4 or later. Use the command
+ flex --version
+ to check you have a new enough version of flex
+
+
+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 and modified for
+ PostgreSQL V6.3 by Lasse Hiller Petersen )
+
+ Apply the following patch:
+
+*** ./backend/Makefile.orig Tue Mar 3 15:33:58 1998
+--- ./backend/Makefile Tue Mar 3 15:39:27 1998

+! rm -f SUBSYS.o
+! $(CC) -o postgres *.o ../utils/version.o $(LDFLAGS)
+
+ $(OBJS): $(DIRS:%=%.dir)
+
+
+
+
+ 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
+--- src/makefiles/Makefile.irix5 Thu Mar 5 17:01:13 1998
+***************
+*** 6,9 ****
+ %.so: %.o
+ $(LD) -G -Bdynamic -shared -o $@ $<
+
+!
+--- 6,9 ----
+ %.so: %.o
+ $(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.
+
+
+----------------------------------------------------------------------
+Section 2: Deinstalling PostgreSQL
+----------------------------------------------------------------------
+
+2.1) Why can't I move the executable files?
+
+ By default, the IRIX port uses the BSD compatible version of
+ install from /usr/bin/X11. If you read the man page for this
+ version of install, you will see that it is not meant for
+ end-user use; it has the interesting side-effect of chowning
+ files it installs to root.
+
+ You should still be able to delete the files as you (the
+ postgres user) will own the directory in which they are
+ stored.
+
+ The normal IRIX install program cannot be used easily as it
+ takes its arguments in the reverse order. It is therefore
+ recommended to use the GNU version of install (ginstall).
+ See Question 1.4
+
+
+----------------------------------------------------------------------
+Section 3: Extending PostgreSQL
+----------------------------------------------------------------------
+3.1) How do I compile a C program to create a function for extending
+ PostgreSQL
+
+ Here is a sample command line:
+
+ cc -I/usr/local/PostgreSQL/include/ -I/usr/local/PostgreSQL/src/backend
+
+ -shared -o funcs.so funcs.c
+
