Re: Error building 32 bit on 64 bit linux system - Mailing list pgsql-hackers

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:
