Using DjVu as a library

[Bruno Baruffaldi]

Hello, I would like to use DjVu in project as a library but I cannot find any documentation related to DjVu C++ library.

Can someone tell me how to compile this code?

// File A.cpp
#include <iostream>
#include <libdjvu/ddjvuapi.h>
#include <libdjvu/miniexp.h>

int main(void){

    std::cout << ddjvu_get_version_string() << std::endl;

    return 0;
}

I am trying to compile with g++ -std=c++11 A.cpp -o A

If I change ddjvu_get_version_string() for DDJVUAPI_VERSION the program works. But if I use the function g++ fails with an undefined reference.
Is there any namespace or flag that I must add to compile?

Try to find out with pkg-config:

$ pkg-config --cflags ddjvuapi

$ pkg-config --libs ddjvuapi
