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.
What does your app care? Unless you are writing the app directly to libpq? Which version of Linux are you running? Sincerely, Joshua D. Drake
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?
