I have two module in Qt
1. SapPackets : lib
2. SapApplication : app
pro file for both module
SapPackets.pro has Qt -= gui
SapApplication.pro has Qt += core gui xml
Target OS is Windows 7
there is a class SapEntity in SapPacket.lib
#ifndef SAPENTITYCLASS_HPP
#define SAPENTITYCLASS_HPP
#include <QString>
namespace Sap
{
namespace Entity
{
class SapEntityClass
{
protected:
unsigned short mush_Id; /* Entity Id */
QString msz_title; /* Entity Title */
public:
SapEntityClass(const unsigned short Id,const QString title);
unsigned short GetId() const;
QString GetTitle() const;
};
}
}
#endif
implementation file of SapEntity is
#include "SapEntityClass.hpp"
using namespace Sap::Entity;
SapEntityClass::SapEntityClass(const unsigned short Id,const QString title)
:mush_Id(Id),msz_title(title)
{}
inline
unsigned short SapEntityClass::GetId() const
{
return mush_Id;
}
inline
QString SapEntityClass::GetTitle() const
{
return msz_title;
}
SapApplication.pro has following line for adding SapPackets.lib
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../SapPackets_Build/release/ - lSapPackets
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../SapPackets_Build/debug/ -lSapPackets
else:unix: LIBS += -L$$PWD/../SapPackets_Build/ -lSapPackets
INCLUDEPATH += $$PWD/../SapPackets
DEPENDPATH += $$PWD/../SapPackets
Main function in SapApplication
#include <iostream>
#include "SapEntityClass.hpp"
using namespace Sap::Entity;
int main(int argc, char *argv[])
{
SapEntityClass obj(56,"Sample");
std::cerr<<obj.GetId();
return 0;
}
Problem:
I am getting following error on Compilationa
main.obj:-1: error: LNK2019: unresolved external symbol "public: unsigned short
__thiscall Sap::Entity::SapEntityClass::GetId(void)const " (?
GetId@SapEntityClass@Entity@Sap@@QBEGXZ) referenced in function _main
Please help me to resolve this....
