OpenCASCADE configuration problem

Dear all, I like to work with Opencascade and eclipse, i found a problem in configuring the libraries into eclipse!
I try to manage with changing the directories in eclipse and try the following coding

#include
#include
#include
#include
#include
#include
#include
#include
#include
#include
int main(void) {

STEPControl_Reader reader;

IFSelect_ReturnStatus stat = reader.ReadFile("screw.stp");

return 0;
}

Found the following output error:

**** Build of configuration Default for project Name1 ****

make all
