For any C++ Boost library, how can one find out which Boost library(ies) it requires ?
Example (not necessary a working example though): Boost library "test" requires Boost library "date_time".

Not sure what you mean. If you have a boost library, why would it need other boost libraries? – Brady May 30 '12 at 14:53

One must look deep into their own soul, and/or check the documentation. Typically, Boost does includes rather well (both of headers and `#pragma lib`), so you rarely have to worry about this. – ssube May 30 '12 at 14:57

@unwind, reminded me of "GNU is Not Unix" :) – Brady May 30 '12 at 15:02

boost comes with a tool to gather the dependencies of a library.
It is called bcp. If you just want a list of files, you have to use the --list option.

It has happened to me as well. Especially, with questions with short answers, like these. – mirk May 30 '12 at 15:12

If you want to find out those dependencies to isolate the components your software requires, you can use bcp (Boost Copy)
It copies selected boost libraries and all its dependencies to a target location.
Eg
bcp regex /foo
copies the complete regex library and its dependencies to /foo
Disclaimer: I do not have any practical experience with bcp.
EDIT:
If you only want to check on which compiled library a compiled library depends, you can either use ldd <boost_library_filename>.so on Linux or Dependency Walker on Windows.

A modern solution is to use boost Dependency Report (available starting from boost v1.66.0).
