Dear all,
what do you people use for organising code for optimal compile time?
I have an app , gui + core + file ops, which is growing and compile time is
too long, need a better way of organising the code. Could someone please
highlight what could be done to speed up compile time, tia.

The simplest "trick" I use is forward-declaring all that can be instead
of defining.

Splitting your code into components and building them separately should
also help. See John Lakos' "Large-Scale C++ Software Design" for more
information on separating your code into components.

U++ (upp.sf.net) provides build technology (blitz-build) that in most
cases reduces build time 4-8 times.
It works by grouping .cpp files together and compiling them as single
unit. This way included files are processed just once. As C++ compiler
spends most time parsing headers (usually it is hunderds of thousands .h
lines and thousands of .cpp lines), compile time reductions are really
dramatic.
Of course, it needs more magic to work than can be explained in a single
post :)

What Victor and Mirek said, but also use precompiled headers if you
can.

Avoid networked drives, especially for intermediate files.
