Maybe you forgot to setup the environment?

Reason could be your system might not have g++ installed or path to g++ is not set.

check g++ version
if version not found than install g++ compiler
Set PATH variable to g++ location . in linux g++ is in path - "/usr/bin/g++"
Try Setting below variables in qmake file
```
QMAKE_CC = gcc
QMAKE_CXX = g++
```

try compiling through command line :

qmake projectName.pro -r -spec linux-g++
