Re: [GD-General] Compile times

[mike w. <mi...@ub...>]

the full sourcecode to our game engine currently runs about 20 megs.  can't
say i've done a full recompile in a while, so i'm not sure how long it would
take to build the entire sucker.

the major benefit we have to compiling the source is the complete seperation
of various parts of the engine into dlls & other libraries - we only need to
recompile these as necessary (ie if we make low-level changes to the drivers
or graphics engine), the main source itself is only about 5 megs - the rest
is in 'compile as necessary' libraries.

this also lets us have various 'versions' of the various libraries in-house.
for example we have a 'stable' driver, ie tested working versions of stuff
that the designers can use and know the functionality is there, and we also
have 'development' drivers that are the bleeding edge drivers that most of
the designers don't really need to access, only one or two designers have
access to the dev drivers - and they are used to test & break the newer
features before we unleash them on the rest of the team....

we have seperate dlls' for open gl drivers, software drivers, d3d drivers,
network libraries, etc...

works out well, if certain machine configurations barf on the newer updates,
they can roll back to the previous drivers & still be productive while the
programmers work on bug-fixes for their particular test-cases...
