Postgres 32 bit development libraries on x86_64 bit platform

[bs_madhu]

Hi
I have two question regarding the postgres application on openSUSE 11.1.

1. Why their is no 32 bit developement libraries of postgresql present in x86_64 directory .
postgresql-libs-32bit-devel-8.3.5-1.10.x86_64.rpm

2. What is the difference between 32bit rpm file present in x86_64 directory and i586 directory ?

Thanks
Madhu

I think this package provides 32 bits library compatibility for 64 bits
libraries. This is only needed on 64 bits systems.

On i586 directory there are only "postgresql-libs-8.3.5-1.10.i586.rpm"
and "postgresql-devel-8.3.5-1.10.i586.rpm" packages.

On 32 bits systems there is no need for "32 bits library-devel
compatibility" as they are "natively" incorporated :-)

Hi
Thanks for the replay.
We are trying to compile our software in 64 bit environment targeting both 32 bit and 64 bit machines.
To compile we need 32 bit and 64 bit developement libraries of postgres. One thing we observed is openSUSE distro does not have 32bit development libraries in x86_64 folder.

What is the recomended approch to complie on 64 bit system targetting both 32 and 64 bit platforms.

Thanks
