Dear all, we use boost a lot in our code, but unfortunately this slows down the build times enormously. Although we use the precompiled header in Visual Studio, tracing the includes (with the /showincludes option), it seems that even relatively basic libraries (e.g. tuples, boost\utility.hpp, boost function and boost bind) end up in a massive include of mpl and type traits header files. So I begin to wonder if this wonderful template and preprocessor stuff is really such a good idea for those basic library. Besides that it doesn't improve the readability of the source, my guess is that it has a negative effect on short build times. Can a boost guru comment on this? Note that this is not a criticism, only an observation. I always like to write a boost bind construction, especailly with the == addition in 1.33. Wkr, me
