[SOLVED] QtSingleApplication
Hi All!
I write in VS2008, I wont create QtSingleApplication application. I’m create Qt Application, then add to my project path to “src” files QtSingleApplication, then rewrite QtApplication to QtSingleApplication, write
- #include "QtSingleApplication";
- 1>LINK : D:\Projects\test\test\Debug\test.exe not found or not built by the last incremental link; performing full link
- 1>main.obj : error LNK2019: unresolved external symbol "public: __thiscall QtSingleApplication::QtSingleApplication(int &,char * *,bool)" (??0QtSingleApplication@@QAE@AAHPAPAD_N@Z) referenced in function _main
- 1>D:\Projects\test\test\Debug\test.exe : fatal error LNK1120: 1 unresolved externals
Who can tall, why this happen? What is I do wrong?
Code main.cpp:
- #include "test.h"
- #include "QtSingleApplication"
- int main(int argc, char *argv[])
- {
- QtSingleApplication a(argc, argv);
- test w;
- w.show();
- return a.exec();
- }

Ok. After adding, I have a more errors: (if i add all of headers and source files “qtlocalpeer”, “qtlockedfile”, “qtsingleapplication” and “qtsinglecoreapplication”)
