I checked out the v4.0.10 tag (commit 6c0f888005ab88914cb985e6420b46b959f754ca) to study how to customize QGC build. As per instructions, I cleared the build directory, renamed custom-example directory to custom and built the project. Upon successfully building the code, I was able to run the GUI, then created and ran missions for a simulated vehicle. However, the custom fly view overlay, defined in CustomFlyView.qml, does not get displayed at all. I have been unable to identify any potential reason. I have not made any change to the commit I checked out. Any input is greatly appreciated! Thanks a lot!
It looks like the custom fly view overlay works as expected up to tag 4.0.6 on Stable_V4.0 branch. From 4.0.7, it does not work. I am still trying to figure out what changed. I am new to qgroundcontrol and as such it is taking longer for me to work through things I will greatly appreciate any input! Thanks!
