Hello everybody! This is my first project using U++. I want to build a program to solve the TRANSPORT PROBLEM, it's just then beginning, but I dont understand the error description. Details are below:
Source:

}

GUI_APP_MAIN
{
//int m,n;
Tranmission().Run();

}

In addition, there are 2 files: Tranmission.lay and Tranmission.iml, but they aren't involved with the problem (I think so Very Happy

). The parts of source code that are after "//" and covered by /*....*/ are just be add to source afterwards. And these are error descriptions:

There were errors. (0:00.60)

Please, help me. I dont know what happen. It's just the start to make interface, even I have not yet go to the main part of program. When I build any examples contained with U++, it's good.
