32-bit software on a 64-bit OS

Mufasa · 04-12-2010, 05:57 AM

Hello all,

With Windows, if I have a 64-bit OS, I can usually install a 32-bit SW product on it.

I have a 64-bit Opensuse product (Opensuse 10.3 - long story).

Here is information on installing Zimbra (ZCS 5.0) on top of Opensuse 10.3

http://www.zimbra.com/forums/install...ete-guide.html

But - the software that is mentioned in the guide (the one you need to download) is here

http://www.zimbra.com/downloads/os-downloads.html

From above, you can see an item for Opensuse 10.3 *** but 32-bit *** version.

In general, is it possible to install 32-bit Software in an 64-bit system?

TIA

You will need a system containing both 64bit and 32bit libraries plus a kernel capable of running both 64 and 32bit apps.

edit: it's called a 'multilib' system

Thanks for responding

-> How can one tell whether or not they have a "multilib" system?
-> How can I tell whether or not my kernel is capable of running both 64-bit and 32-bit apps?

TIA

Other than installing some 32 bit software and seeing what goes wrong, I don't know how to tell if you have multi-lib support.

You might try this command to see if any 32-bit software is already installed in some likely place such as /usr/bin

Code:

file `find /usr/bin` | grep 32-bit

all 64 bit libs reside in /usr/lib64, 32 bit libs in /usr/lib
Look and see what's in the 32 bit directory

Code:

du -s /usr/lib
