Interdependency of libraries should be taken into consideration . When static linking is not possible , it is necessary to compile the program in question in the operating system version causing incompatibility with the other version of the operating system where the program is compiled and working successfully . Another point to consider and study is the procedures , conventions and practices used in the generation of Linux distributions . Mehmet Erol Sanliturk
