v5.0.8 native build fails with latest PX4-GPSDrivers (GPSDriverUBX ctor signature changed)

Description

Description

Building QGroundControl v5.0.8 natively on Linux fails after recent updates in the PX4/PX4-GPSDrivers repo. The QGC source code itself is unchanged on our side; the breakage appears to come from an upstream API change in GPSDriverUBX constructor (now requires an additional Settings argument).

Environment

• QGroundControl: v5.0.8
• OS: Linux (native build)
• Compiler: g++ (via cmake/ninja)
• Qt: 6.8.3 (from build log)
• Build system: CMake + Ninja
• Dependency manager: CPM (px4-gpsdrivers via CPMAddPackage)

Steps to reproduce

• Checkout QGC v5.0.8
• Configure + build natively (cmake/ninja)
• Build fails in src/GPS/GPSProvider.cc when compiling GPSProvider.cc

Actual result

Build stops with:

/home/.../src/GPS/GPSProvider.cc:223:120: error: no matching function for call to
'GPSDriverUBX::GPSDriverUBX(GPSHelper::Interface, int (*)(GPSCallbackType, void*, int, void*), GPSProvider*, sensor_gps_s*, satellite_info_s*)'

candidate: 'GPSDriverUBX::GPSDriverUBX(Interface gpsInterface, GPSCallbackPtr callback, void *callback_user,
                                       sensor_gps_s*, satellite_info_s*, Settings)'
candidate expects 6 arguments, 5 provided

So QGC calls the 5-argument constructor, but px4-gpsdrivers now expects 6 arguments (added Settings).

Expected result

v5.0.8 should build successfully using its default dependency resolution, or the dependency should be pinned to a compatible tag/commit.

Workaround (temporary fix)

Pin px4-gpsdrivers to an older compatible commit in src/GPS/CMakeLists.txt:

CPMAddPackage(
    NAME px4-gpsdrivers
    GITHUB_REPOSITORY PX4/PX4-GPSDrivers
    GIT_TAG caf5158061bd10e79c9f042abb62c86bc6f3e7a7
    SOURCE_SUBDIR src
)

With this pin, the build succeeds.

Need to backport the change I added to master yesterday. Those dependencies should have been pinned to a commit

Thanks for confirming and for handling the backport. Appreciate it.

When that happened some days ago, I search as crazy those repos to find new info. I made a "fix" passing the new argument required now. Here is What I passed to the new driver. I don't know and I don't think it's okay but It let me built so I share the info.

GPSDriverUBX::Settings(0b111, kGPSHeadingOffset, UBX_BAUDRATE_M8_AND_NEWER, true, GPSDriverUBX::UBXMode::GroundControlStation)
