    But when I compile project it give error as follow :

    ../src/.libs/ undefined reference to `ABC::ABC()'
    ../src/.libs/ undefined reference to `ABC::GetFileName(QString)'

    Read the forum runes - especially about cross-posting.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
