Undefined link to `boost :: chrono :: system_clock :: now () '- Boost and cpp-netlib

Question

I came here to ask for a fix that disappointed me. Lot. First of all, I am on Windows, I use MinGW as a compiler (C ++).

I am having trouble getting a program to work using cpp-netlib and SSL (trying to POST to the https site). I believe that everything is in order, except for this one mistake, which evades me.
C:\boost_1_50_0\boost_1_50_0\stage\lib\libboost_thread-mgw46-mt-1_50.a(thread.o):thread.cpp|| undefined reference to 'boost::chrono::system_clock::now()'

I am sure that I am associated with the cron, as well as with all .a libs in BOOST_ROOT/stage/lib . I tried reordering so that chrono was connected before the stream. Nothing helped. I tried to define BOOST_CHRONO_INLINED in my IDE settings and some conf.hpp to make it only a header, which didn't help.

I am sure this is a newbie question, and I hope someone can give me a quick solution. I wrote it in a hurry because I have to be somewhere, but if you need more information, tell me about it, and I can write it more carefully when I get home. Thanks!

It is not right. Boost.Thread depends on chrono, so chrono needs to be linked after the stream, so the linker knows which characters are needed, and can find which library defines them and refers to it.
