building rpm packages for older distributions.

[Elias Abacioglu]

Hi,

I want to build some cross-compatible packages.

My build server is a CentOS 6.2 and has rpm-libs-4.8.0 and rpm-4.8.0.
The problem is that i want to install rpms on older distributions.

For instance one server has rpm 4.4.2.
It get the following errors:
error: Failed dependencies:
    rpmlib(FileDigests) <= 4.6.0-1 is needed by xxx
    rpmlib(PayloadIsXz) <= 5.2-1 is needed by xxx

So the question is, is there a way to build packages with "legacy" support?
Like some way to force the rpm to use other payload and filedigest methods
that have wider support.

Cause it feels kind of backwards to install centos 4 to build rpm packages
that should work on old and new versions of rpm.

Thanks
