Hello friends,

I am new in this forum and Qt. I've started a project on Qdevelop. But whenever i tried to built the typed program, it says

"Build (make)...
make: g++: Command not found
make: *** [build/mainwindowimpl.o] Error 127
g++ -c -pipe -g -Wall -W -D_REENTRANT -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -Ibuild -Ibuild -o build/mainwindowimpl.o src/mainwindowimpl.cpp
---------------------- Build finished without error----------------------"


and when i try to build it,

it says.

"program doesn't exist, run built "

please help me,

thanks in advance
