c++ - Unable to access static const variable declared outside the class -

i have declared static const variable before configuremanager.h class declaration this:

static const std::string configure_file_path = "./abc.conf"; class configuremanager: private boost::noncopyable { ... }; 

later on when trying access configuremanager.cpp class methods, giving me segmentation fault error.

#include "configuremanager.h" void configuremanager::xyz() {        std::cout << "configurefilepath " << configure_file_path << std::endl; } 

i using g++ compiler in ubuntu environment.

i had no issues inserting, compiling, , running code. string sent console. post error message or more code...
