well the linker is searching for a function (constructor) GPSDriverUBX::GPSDriverUBX but cannot find it (or maybe it cannot find the correct overload in case there are multiple definitions of this functions. It also says, this function is called from the function void GPSProvider::run(void).

So what I would do:

Completely clean the build environment and rebuild everything
Make sure you link the file that contains GPSDriverUBX::GPSDriverUBX (in case that's an external library, make sure you link the library)

In case that does not help, have a look at the linker command line in the build output if you can spot something unusual.

Hi,

In addition to what @aha_1980 wrote, if that function is yours, are you properly exporting it ?
