Please post a backtrace from the debugger.

Hi

i have included my debug details.... it showing login.ui is unfound...

it's compiler output and has nothing to do with debug backtrace. Just use debugger and you will see where the crash appeared.

Hi

Already i haven so many debugger statements...

complier is not entering even main .cpp ..



How do solve thisa issue...


Please help me

So it crashes or it doesn't compile? And do you know the difference between debugger and compiler?

No, please tell me the difference...

No, please use www.google.com to get required knowledge to write, debug and deploy an application in C++.
