Hi,
I used AP_Declination library from ArduCopter on 1.0.5 IDE.
This is used to find magnetic declination from lat/lon positions.
After upgrading to 1.8.10 I'm having issues where the IDE can't find the right folder path.
Library path for 1.0.5, /arduino/library/ardupilot/library/AP_Declination
When I try the same for 1.8.10, no library is found.
If I place the library directly into the folder arduino/library/AP_Declination.
The IDE finds the library but all the include's inside AP_Declination.h file is not found because there they are typed "#include /HAL/HAL.h.
Tried manually changing the path when compiling, but as one error is fixed another surfaces.
Anyone have a suggestion on how to fix this?
