Error building 32 bit on 64 bit linux system

All,<br /> I am trying to build 8.2.5, forcing to a 32 bit build on a 64 bit system. I have set CFLAGS=-m32, and I run
theconfigure and make/make install as follows:<br /><br /> setarch i386 ./configure<br /> setarch i386 make<br />
setarchi386 make install<br /><br /> However, I get the following error (using timezone for example):<br /><br /> $

I'm not sure, but maybe linker also needs a switch to make 32bit output.

"man ld" IYF.

It looks like you need the --oformat option to tell the linker you want 
32bit output.

Of course you won't find the SUBSYS.o files - it it the creation of 
those that is failing.

Thanks Andrew, I missed the little -o in front of the SUBSYS.o. I did find that if I did "export LDEMULATION=elf_i386"
Iwas able to link successfully. Now I just need to tell configure that I want to use the 32 bit perl libs, not the 64
bitones it keeps finding by using:<br /><br /> $PERL -MConfig -e 'print $Config{archlibexp}'<br /><br /> Both 32 and 64
bitlibraries are installed on my system, but the return from the above command within configure points to the 64 bit
libs,as the perl executable is a 64 bit file. I think my better option is to build my 32 bit versions on a 32 bit
CentOSVM I have setup.<br /><br /> Doug<br /><br /> On Mon, 2008-02-18 at 09:48 -0500, Andrew Dunstan wrote:

This problem is solved by using

export CC="gcc -m32"
export LD="ld -melf_i386"

before doing

setarch i386 (./configure ... ; make)
