All i found in Stackoverflow, nothing help in my case, maybe there is something that my eyes can't see? undefined reference to symbol occurs, when i include these headers #include <boost/log/expressions.hpp>
#include <boost/log/utility/setup/file.hpp>

Oh my. You have many problems here. As Jesper said, linker issues are normally not related to #include files.
First, you should never add libraries to your compile lines: that is, lines that create object files (lines that use the -c compiler option). So this rule:
obj/%.o: src/%.cpp
@mkdir -p obj
@g++ -std=c++11 -DBOOST_ALL_DYN_LINK -pthread -lboost_log -lboost_thread -lboost_system -lboost_log_setup -lboost_filesystem -c $< -o $@
is wrong: you should not have any library options here (-l or -L). It should just be:
obj/%.o: src/%.cpp
@mkdir -p obj
@g++ -std=c++11 -DBOOST_ALL_DYN_LINK -c $< -o $@
However, all of this is irrelevant because none of this makefile is actually used except for one rule: the one that creates the program. You've created a bunch of variables that are never used, and a bunch of pattern rules which are ever used.
Next, you should never use quotes inside a makefile variable unless that variable contains an entire shell script that requires quotes. Make itself doesn't care about quotes, it just treats them the same as any other character. So, you should use:
PROGNAME := program
Next you should use the variable in the target, else it has no purpose:
bin/$(PROGNAME): ./bin lib/libStat.a src/main.cpp $(HEADERS)
And in your recipe you should use $@ to refer to the target.
Next, the order in which libraries are listed on the link line is critically important, and it must be more general libraries first, and libraries they depend on afterwards. So for example, your library Stat should come first, followed by Boost libraries, and finally at the end system libraries:
@g++ -std=c++11 src/main.cpp -DBOOST_ALL_DYN_LINK -pthread -L lib -l Stat -lboost_log -lboost_log_setup -lboost_thread -lboost_system -o bin/$(PROGNAME) -I /inc -I /usr/include/boost/log/utility/setup
Note that your -I option is wrong; you wrote -I /inc but you want (I assume) -I ./inc.
I have no idea why you're linking files from the source directory to the include directory. Maybe if you fix your -I option, you won't need to do this anymore.
