It is very important to choose the right set of tools and build environment in order to reduce the migration effort to the barest minimum. It should be noted that all popular open-source build tools (GNU/GPL) and utilities are available on Oracle Linux. It is much easier to transition to Oracle Linux if you can maintain the same build tools and build environment on the two systems.
The following points need to be taken into consideration while finalizing the target build environment:
Build tools and other build dependencies (gmake, dmake, make, ANT, and so on).
Tools used by the applications.
Command-line options provided by the tools.
