Thread: Build system problem in 8.3.x
Hi, we have come across a problem in 8.3.x (8.3.5 and 8.3.7 was tested) while building PostgreSQL for 32-bit on 64-bit RHEL5 and Fedora 9. The following defines were used before running configure: export CFLAGS="-m32" export LD="ld -melf_i386" The above are needed because when SUBSYS.o files are created, the $(LD) ... lines don't contain $(LDFLAGS) anywhere, so overriding $(LD) on the command line has to be done instead. However, there's one additional problem that can be solved by the attached one liner. The problem is that during building the core, something (test/regress) requires contrib/spi/refint.so to be built. The error follows: make -C ../../../contrib/spi refint.so autoinc.so make[3]: Entering directory `/home/zozo/Schönig-számlák/lucent/postgresql-8.3.5/contrib/spi' gcc -m32 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -fwrapv -fpic -DREFINT_VERBOSE -I. -I../../src/include -D_GNU_SOURCE -c -o refint.o refint.c gcc -shared -o refint.so refint.o /usr/bin/ld: i386 architecture of input file `refint.o' is incompatible with i386:x86-64 output I tried building contrib manually, but it turned out that the same error happens whenever contrib/*/Makefile contains MODULES instead of MODULE_big. I modified Makefile.port in the attached patch, and now all the contrib files also build correctly. Best regards, Zoltán Böszörményi -- Bible has answers for everything.

If you're willing to override $(LD), seems you could get around that additional problem by overriding $(CC) as well: export CC="$(CC) -m32" export LD="ld -melf_i386" > *** src/Makefile.port.old 2009-08-27 10:56:46.000000000 +0200 > --- src/Makefile.port 2009-08-27 10:56:46.000000000 +0200 > *************** > *** 11,16 **** > endif > > %.so: %.o > ! $(CC) -shared -o $@ $< > > sqlmansect = 7 > --- 11,16 ---- > endif > > %.so: %.o > ! $(CC) $(CFLAGS) -shared -o $@ $< > > sqlmansect = 7 I guess we should change that rule to use $(LD) instead of $(CC), and include $(LDFLAGS) in the rules that build SUBSYS.o. Or maybe there's a reason they are what they are, I don't know. (SUBSYS.o's are gone in 8.4 anyway) -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com

Ultimately CFLAGS and LDFLAGS should be the way to control special compilation or linking. But there's a problem: export CFLAGS="-m32" export LDFLAGS="-melf_i386" $ ./configure --prefix=/home/zozo/pgc835_32 --enable-depend --enable-debug checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking which template to use... linux checking whether to build with 64-bit integer date/time support... no checking whether NLS is wanted... no checking for default port number... 5432 checking for gcc... gcc checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details.

Also, modifying LD and CC may stir up some problems in the USE_PGXS=1 machinery, I don't know. Adding $(LDFLAGS) to Makefiles would be the way to go, some discussion is needed. >> *** src/Makefile.port.old 2009-08-27 10:56:46.000000000 +0200 >> --- src/Makefile.port 2009-08-27 10:56:46.000000000 +0200 >> *************** >> *** 11,16 **** >> endif >> >> %.so: %.o >> ! $(CC) -shared -o $@ $< >> >> sqlmansect = 7 >> --- 11,16 ---- >> endif >> >> %.so: %.o >> ! $(CC) $(CFLAGS) -shared -o $@ $< >> >> sqlmansect = 7 >> > > I guess we should change that rule to use $(LD) instead of $(CC), and > include $(LDFLAGS) in the rules that build SUBSYS.o.

I see that this change is already applied to Makefile.linux in HEAD, but I'm not sure it's worth back-patching by itself. We know that on Darwin, which is where the most work has been done on cross-arch/multiarch builds, you really need the SUBSYS.o-ectomy as well to make multiarch builds simple. And we're *not* back-patching that. I'm inclined to say that making this workable is an 8.4 feature and you should use 8.4 if you need it. regards, tom lane
