I have a set of programs for analyzing radiation data and I want to build packages for Red Hat Linux versions 4.x – 6.x. Is it possible to build these packages on a single build server running a single version of Red Hat Linux or do I need to build the version 4.x package on a server running version 4.x and the version 5.x package on a server running version 5.x?
If I can build packages for several versions on a single server, must that server be running the newest version or the oldest version of the OS?
You need to build
toolchainfor different OS environments (toolchain for Redhat 4.x and 5.x) and with in toolchain you can build packages for specific OS. toolchain is like achrootenvironments.You can create multiple Virtual machine using
KVMand build many version of packages using single node..You can use
UML(User Mode Linux) which is quite interesting… Check out following Linkhttp://uml.devloop.org.uk/howto.html
