Program portability

Question

How to make sure that my program will be fully portable?

Answer 1

• Make it standards compliant. At least a common subset of the standard that is implemented by vendors on all platforms you intend to deploy your application on.

• Factor out platform specific portions from platform-independent ones. Typically, the lowest layer or two should deal with the platform.

• Keep abreast with changes of:

  • Platform/OS APIs
  • Tool chains
  • Language features

• Test, Deploy. Rinse and repeat.
