Undefined symbol with JsonCPP library in Linux 64. What am I missing?

I'm using JsonCPP as a parser for Json in C++, the problem is when I declare my var Json::Value root;, its compiles very well but when I use it the program crashes showing this msg: undefined symbol: _ZN4Json5ValueD1Ev. What I missing?

I thought that is was a linker problem so I put my library libjson_linux-gcc-4.1.2_libmt.so in /usr/lib and /usr/lib64, and the .h to /usr/include/json so when I call for the library in my code I do #include <json/json.h>.

Everything is fine because I can compile it very well! but I recieve the same crashes.

Is there any path that I am missing to link?

Thank you all!

PD: I forget to say that I'm not compiling with g++, I'm compiling with a makefile

This works for me, putting the libjson_linux-gcc-4.1.2_libmt.so to the same dir of your program located when running it.

In addition to including the header file, you need to link to the library as well.

At the linking stage, add the argument -ljson_linux-gcc-4.1.2_libmt
