Which Boost libraries are header-only? And which require building libraries?
Does such a list exist?
650
Most Boost libraries are header-only: they consist entirely of header files containing templates and inline functions, and require no separately-compiled library binaries or special treatment when linking. The only Boost libraries that must be built separately are: Boost.
Boost Process is header-only, so you don't have to compile it separately.
Boost. DateTime: This dependency is mandatory, but even if Boost. DateTime is a non header-only library Boost. Thread uses only parts that are header-only, so in principle you should not need to link with the library.
By default, Boost. Asio is a header-only library. However, some developers may prefer to build Boost. Asio using separately compiled source code.
The list of libraries that require building is here for Unix-like systems, and here for Windows.
For the current release, 1.58, both are the same:
A few libraries have optional separately-compiled binaries:
Note that some libraries may depend on these (for example, Asio depends on System as pointed out in the comments), so you may still need to build something even if the library you want isn't on the list.

Actually, even ./bootstrap.sh --show-libraries is somewhat incorrect too, because some libraries depend on that listed libraries.
It is possible to get list of header-only libraries with the Boost BCP tool, launching the tool on every library and removing those linking any binaries. That is what was done in How To Build Header Only Boost.
For Boost 1.67.0 the resulting list was:
