I'm trying to build postgresql and odbc from source on x86_64 Linux
hosts but I need to run them in 32-bit addressing mode since my app is
not 64-bit ready yet.
Simple test programs can be built as 32-bit apps (if the libraries are
installed) via gcc's -m32 option.
I checked for postgres configure options to do something similar, but
didn't find anything. I experimented with setting environment
variable CFLAGS to -m32 and it does seem to be picked up by
configure/make, but then 'ld' gets errors:
/usr/bin/ld -r -o SUBSYS.o heaptuple.o indextuple.o indexvalid.o
printtup.o scankey.o tupdesc.o
/usr/bin/ld: Relocatable linking with relocations from format
elf32-i386 (heaptuple.o) to format elf64-x86-64 (SUBSYS.o) is not
supported
So ld needs some additional options of some sort, but it looks like
that would involve some complicated specifications of various libraries.
I checked the archives, but didn't see anything about this.
Is there any way to do this? Any plans to add it? Any hints on what
I could try?
Thanks much,
