=== Source code ===
[[Weather monitor installation | Installation issues]] issues.


Code is found here (on SVN)
[[Wearher monitor modules | Modules]]

C++ code is then in the ''monitor directory''.
 
== CMake problem ==
 
=== GeographicLibConfig.cmake ===
 
The find package
find_package(GeographicLib REQUIRED)
in cmake fails, as the file GeographicLibConfig.cmake is not found.
 
This can be fixed by renaming the provided file ''FindGeographicLib.cmake'' by
cd /usr/share/cmake/geographiclib
sudo ln -s FindGeographicLib.cmake GeographicLibConfig.cmake
 
=== XKB ===
 
Missing library, and CMake complains:
 
-- Could NOT find XKB (missing: XKB_LIBRARY XKB_INCLUDE_DIR) (Required is at least version "0.5.0")
 
The solution was to install
 
sudo apt install libxkbcommon-dev
 
This occurred on Raspberry Pi 5 using 64bit default OS.
