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. || I'm kinda new to this, but...unless your app is compiled and linked into PG shared objects, I don't think it'll care whether it's talking to a 32 or 64 bit executable. Now, if 32 and 64 cannot coexist on your Linux builds, that's a different issue. 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? || you need to set the environment in the os/shell. I don't know how to do this on your system. on AIX, though, it's "export OBJECT_MODE=64".
