Cross-compiling full Qt 5.11.x for Raspberry Pi: error with QGeoMap class in Qt Location module
Pablo J. Rogina
It looks like the default cross-compiler (GCC 4.9) used as part of those steps (from Raspberry tools repository) is kinda old, and just using a new /more up to date GCC cross-compiler (i.e. by building GCC 8.1 yourself) solves the issue.
Great, thanks for info!
