Hello Ole,

The "Quick example step by step" is incomplete. You need to add:

precompiled.h:
Qt Code: 
  1. #ifndef _QX_TEST_PRECOMPILED_HEADER_H_
  2. #define _QX_TEST_PRECOMPILED_HEADER_H_
  3.  
  4. #include <QxOrm.h>
  5.  
  6. #include "export.h"
  7.  
  8. #endif // _QX_TEST_PRECOMPILED_HEADER_H_
To copy to clipboard, switch view to plain text mode 

export.h
Qt Code: 
  1. #ifndef _MY_TEST_EXE_EXPORT_H_
  2. #define _MY_TEST_EXE_EXPORT_H_
  3.  
  4. #ifdef _BUILDING_MY_TEST_EXE
  5. #define MY_TEST_EXE_DLL_EXPORT QX_DLL_EXPORT_HELPER
  6. #else // _BUILDING_MY_TEST_EXE
  7. #define MY_TEST_EXE_DLL_EXPORT QX_DLL_IMPORT_HELPER
  8. #endif // _BUILDING_MY_TEST_EXE
  9.  
  10. #ifdef _BUILDING_MY_TEST_EXE
  11. #define QX_REGISTER_HPP_MY_TEST_EXE QX_REGISTER_HPP_EXPORT_DLL
  12. #define QX_REGISTER_CPP_MY_TEST_EXE QX_REGISTER_CPP_EXPORT_DLL
  13. #else // _BUILDING_MY_TEST_EXE
  14. #define QX_REGISTER_HPP_MY_TEST_EXE QX_REGISTER_HPP_IMPORT_DLL
  15. #define QX_REGISTER_CPP_MY_TEST_EXE QX_REGISTER_CPP_IMPORT_DLL
  16. #endif // _BUILDING_MY_TEST_EXE
  17.  
  18. #endif // _MY_TEST_EXE_EXPORT_H_

and a pro file like:
Qt Code: 
  1. TEMPLATE = app
  2. TARGET = test
  3.  
  4. CONFIG += precompile_header
  5. PRECOMPILED_HEADER = precompiled.h
  6.  
  7. INCLUDEPATH += /usr/local/QxOrm/include
  8. LIBS += -L/usr/local/QxOrm/lib -lQxOrm
  9.  
  10. # Input
  11. HEADERS += drug.h
  12. SOURCES += drug.cpp main.cpp
