boost library path include

I installed boost v.1.51.0 and the directory "boost_1_51_0" is sitting under "/home/user1/boost/". To install, i merely unzipped the tar file in "/home/user1/boost/". I'm using the C++ compiler on MinGW.

Now, i'm trying to include the libraries in the code. so far i tried 

#include </home/user1/boost/boost_1_51_0/libs/unordered/test/objects/test.hpp>  
#include </home/user1/boost/boost_1_51_0/test.hpp>
#include </home/user1/boost/test.hpp>
#include <boost/test.hpp>

along with some others. I even tried adding the windows location of "/home/user1/boost/" to the path.

I'm missing something.

#include </home/user1/boost/boost_1_51_0/libs/unordered/test/objects/test.hpp>

This is not going to work. That file might be found, but then it will try to include other files such as <boost/config.hpp> which can't be found in your include path.

#include </home/user1/boost/boost_1_51_0/test.hpp>
                                         ^^^^^^^^

This is not going to work because the file isn't at that location! if you run ls /home/user1/boost/boost_1_51_0/test.hpp you'll get an error because that file doesn't exist.

#include </home/user1/boost/test.hpp>
                            ^^^^^^^^

Same problem here.

It's usually a bad idea to put absolute paths in #include directives anyway, so all the above attempts are wrong. Instead you should include the file as its intended to be used:

#include <boost/test.hpp>

For this to work you need to tell the compiler where to look, so you set the include path with -I dir which in your case needs to be -I /home/user1/boost/boost_1_51_0/ so the compiler looks for boost/test.hpp in /home/user1/boost/boost_1_51_0/ and finds /home/user1/boost/boost_1_51_0/boost/test.hpp and when that includes boost/config.hpp it will find /home/user1/boost/boost_1_51_0/boost/config.hpp as intended.

However, now this will find /home/user1/boost/boost_1_51_0/boost.test.hpp but you seem to want to include a header used by one of the Boost.Undordered unit tests ... I'm not sure why you think you want that. Usually you only want to include Boost headers under boost not under libs

Use the inclusions specified in the boost documentation (typically along the lines of your <boost/test.hpp> example above). But set your CPPPATH/CXXFLAGS (build environment) appropriately. For MinGW, you'll want to add -I/home/user1/boost/boost_1_51_0/.

You need to provide the include directory to your compiler using a command-line argument, e.g. -I/home/user1/boost/boost_1_51_0.

You may also want to actually install boost to a system directory; see http://www.boost.org/doc/libs/1_51_0/doc/html/bbv2/installation.html for details.
