Check if you can find the ui_qtmyapp.h file in your project folder.

<your_QT_Path>\bin\uic.exe qtmyapp.ui -o ui_qtmyapp.h

you'll see a new file, refresh your eclipse project and enjoy

(you still need what rafaelccomp suggested in addition to the above)

Edit: Actually the real problem is that Eclipse can't find "make.exe" to build the project...and hence unable to execute that command in the makefile.

As suggested by someone on another qt forum in 2008 > go to your mingw\bin folder and make a copy of mingw32-make.exe and rename that copy to make.exe

build the project and you'll be fine!
I know this thread is a little old, but to add to this, you can also change the C/C++ Make Project make Build Command to mingw32-make
