That's a fairly vague question. I use thread, data_time, chrono, filesyste=
m, and system on an older embedded ARM processor. These libraries are grea=
t for my application.
I recommend that you not just grab anything you see in Boost indiscriminate=
ly, but rather (as with anything else) look a little deeper and make sure t=
he specific library is suitable. I think it's fair to say that all Boost l=
ibraries have efficiency as a consideration, but are most uncompromising ab=
out correctness. A few years back I used Boost.Python and found that it ge=
nerated surprisingly large code in order to be correct in cases that didn't=
matter to me. The code size almost became problematic. Some libraries (I=
don't have an example at hand) do things that pretty clearly imply a fair =
amount of malloc() and free(). Just because it's Boost doesn't mean it's g=
oing to be suitable for your embedded application.
