32-bit libraries on 64-bit RedHat system

[kazinvan]

The Scalix installation guide pre-installation requirements for RedHat x86_64 systems shows 32-bit libraries for cyrus-sasl-md5, etc. I have all of these libraries installed but they are likely the 64 bit versions. How can you determine the version you have? Can you install the 32-bit libraries with up2date or yum? Will the installer check for missing 32-bit libraries?

Thanks,
Mike

Hi,

The rpms are usually distinguished by i386 for 32bit and x86_64 for 64 bit. I believe the 32 bit libraries can be found on the install media. They can also be downloaded individually.

Thanks, but how do you determine what is already installed on the system. "rpm -aq" does not list if they are 32 bit or 64 bit. Will the installer check?

Thanks.

Hi,

There are a couple of things you can do.

1. Any library that is in /usr/lib/ is a 32 bit library. Any library that is in /usr/lib64/ is a 64 bit library

2. To find out more detail about an installed rpm you can run

Code: Select all

rpm -qa --qf "%{name}-%{version}-%{release}-%{arch}\n" | grep cyrus

this should give you more info.

Cheers,

I now have all the 32-bit installation CDs and all of the libraries needed. When I try to install one of the 32-bit libraries it gives me the message "... already installed". Howerver, the "already installed" libraries are the 64 bit versions located in /lib64.

Do I force the rpm install? I don't want to do that if it will corrupt the system in any way. Also, the libraries have a lot of dependencies on other 32-bit libraries. This may require the installation of a lot of 32-bit libraries in order to get working.

Am I the first one to run into these issues? Is there any documentation on how to get Scalix running on Opterons with RHEL 4 x64?

Thanks,
Mike

You should not having to use the 32 bit installation CDs. All the libraries that you need, afaik, are on the 64 bit installation media as "compat" packages.

I don't see a compat directory or libraries on the x64 CD, all of the RPMS seem to be x86_64. Can you be more specific in what you mean?

Are there any decent instructions on installing Scalix on RedHat x64?

[kazinvan]

There seems to be no clear way to do this, thus I'm re-installing RHEL 4 but the 32bit version this tmie.

[florian]

OK, my fault.... no compat here!

actually on my x86_64 media, I find both RPMs

Code: Select all

cyrus-sasl-2.1.19-5.EL4.i386.rpm
cyrus-sasl-2.1.19-5.EL4.x86_64.rpm


I would assume that installing both of those should be possible without conflicts.

Cheers,
Florian.

As per a previous message, when you try to install the i386 version after already installing the x86_64 version you get a message saying "this package is already installed".

Are you supposed to "--force" the rpm install? Are you *sure* this doesn't cause conflicts?

[florian]

can you get a file list from the rpm??

Not anymore, I just re-installed the i386 version of RHEL 4
