Mission Planner running on FreeBSD 15.0 using Mono

[res2500]

Hello,

I have been testing Mission Planner 1.3.83 on FreeBSD 15.0-RELEASE amd64 using Mono 6.8.

Mission Planner starts successfully without Wine.

Working:

• Flight Data page
• Flight Plan page
• Map rendering and zoom
• Plugin loading

Known issues:

• Some map labels are missing
• Built-in SITL launcher fails with Process.Start()/Access denied
• Some windows do not resize correctly

During investigation I found that the FreeBSD GDAL port disables:

BUILD_CSHARP_BINDINGS
CSHARP_MONO

After enabling those options I was able to build:

libgdal_wrap.so
libogr_wrap.so
libosr_wrap.so

and the corresponding C# assemblies.

I also found a build issue where:

CSHARP_PLATFORM=x64

is correctly stored in CMakeCache.txt, but build.ninja generates:

/platform:

instead of:

/platform:x64

which causes Mono mcs builds to fail.

Question:

Would the ArduPilot / Mission Planner project be interested in documenting or supporting FreeBSD + Mono as an experimental platform?

I am willing to continue testing and provide patches if useful.

export MONO_IOMAP=drive:case
export MONO_WINFORMS_XIM_STYLE=disabled
mono MissionPlanner.exe
