Requirements

  • The split parts should be buildable in an acceptable time.
  • The split should group modules together that have something in common.
  • The boundaries between the groups should be along stable APIs where they exist code and non-code modules should be separated.
  • There should be no cross build dependencies between groups (module A in group 1 depends on module B in group 2 and module C in group 2 depends on module D in group 1).
  • There should be no cross runtime dependencies between groups (module A in group 1 depends on module B in group 2 and module C in group 2 depends on module D in group 1).

Proposal for a code architecture

File:Splitbuild architecture.jpg

I made tests on two platforms (Ubuntu Jaunty, Windows). Here are some results for Linux (all data has been collect on my Toshiba Tecra M5 notebook with 2 GHz Core 2 Duo and 4 GB RAM):
