Hi All

I am brand new to PX4 and QT Creator. I am building the PX4 software for Gazebo on the Mac by following the instructions on the dev guide.

I am confused by the steps shown in the QT Creator on Mac OS video. I followed the steps and loaded “CMakeLists.txt” in QT Creator, but it was nothing like what is shown in the video (assuming QTC has a newer I/F)… I checked QTC’s documentation

[http://doc.qt.io/qtcreator/creator-project-cmake.html](http://doc.qt.io/qtcreator/creator-project-cmake.html)

as well, and it seems that all the steps are correct. But I am not able to build the project.

Some pointer and clarification on how to proceed is much appreciated…

Thx!  
JJ
