Submodule not working

../src/GPS/Drivers/src/ubx.cpp:1981: error: no member named 'heading_accuracy' in 'sensor_gps_s'

Hi,
I've been developing QGC as a hobbyist, and the first I try to compile to QGC, I get this error. Anyway to sort it out??

You need to make sure the submodule points to the right commit -> git submodule update

It worked when i pointed it to an older commit.
