Why does Boost `bcp smart_ptr dir /` copy 6 MB of source code?

Question

So, I wanted to separate only smart pointers from boost for use in my project, and I was asked to use a utility bcp.

Today I compiled it and did it bcp smart_ptr to_copy_to_my_project/.

Result: 6 MB of code in the directory to_copy_to_my_project/.

Are you kidding? I do not want to add 6MB header files to my 100KB project to use smart pointers.

For example, it copies the following win32 file (I am on Linux):

Copying file: boost/thread/win32/basic_timed_mutex.hpp
Copying file: boost/thread/win32/condition_variable.hpp
Copying file: boost/thread/win32/interlocked_read.hpp

Why should I copy win32 files using smart_ptr when I am on Linux?

also:

Copying file: boost/mpl/aux_/preprocessed/msvc60/advance_backward.hpp
...
Copying file: boost/mpl/aux_/preprocessed/msvc70/advance_backward.hpp
...
Copying file: boost/mpl/aux_/preprocessed/mwcw/advance_backward.hpp

and

Copying file: boost/date_time/adjust_functors.hpp

Why is smart_ptr dependent on date_time?

Also, as for all of these tests, which he copied:

Copying file: libs/smart_ptr/test/allocate_shared_esft_test.cpp
...

I do not need it! I just need smart_ptr!

Answer 5

bcp will copy a lot less if you do

bcp shared_ptr.hpp to_copy_to_my_project/.

I think it's too much, I agree.
