Hi: I am learning Qt now. I have written an sample program "Hello.cpp" just copy example. I compile it with "gcc -I\usr\lib\qt\include Hello.cpp" ,got an error "Kapp.h not found". But Kapp.h is still under \usr\lib\qt\include\. What is wrong? Is my gcc installed wrong? By the way ,Can I set environment variable for the lib path ? Thanks! John l.yn
