Suppressing Compiler Warnings from F Prime Core

[astroesteban]

Hey everyone,

Is there a standard FPrime way to suppress compiler flags from the core framework?

I'm working on a project where I have additional compiler flags like -Werror=suggest-override that are resulting in compilation errors with the core F Prime repo.

For now, I wanted to focus on my own component's warnings but the only solution I've found to temporarily suppress fprime-specific warnings are to modify the fprime_setup_global_includes function in the FPrime.cmake file to:

function(fprime_setup_global_includes)
    # Setup the global include directories that exist outside of the build cache
    include_directories(SYSTEM "${FPRIME_FRAMEWORK_PATH}")
    include_directories(SYSTEM "${FPRIME_CONFIG_DIR}")
    include_directories(SYSTEM "${FPRIME_PROJECT_ROOT}")

    # Setup the include directories that exist within the build-cache
    include_directories(SYSTEM "${CMAKE_BINARY_DIR}")
    include_directories(SYSTEM "${CMAKE_BINARY_DIR}/F-Prime")
    include_directories(SYSTEM "${CMAKE_BINARY_DIR}/config")
endfunction(fprime_setup_global_includes)

Marking the included directories as SYSTEM solves this issue for me and allows me to add my project-specific flags on top.

If there's a better way of doing this, I'd appreciate the insight. Thanks!

Yes there should be! Make sure you add new compiler flags after the following line in your project CMakeLists.txt:

fprime/Ref/CMakeLists.txt

Line 33 in 0a822b5

fprime_setup_included_code()

If done afterwards those flags should only apply to your project code. e.g.

fprime_setup_included_code()

compile_options(...)
add_fprime_subdirectory(your subdirectory)
...

Nice! That worked beautifully. Thanks @LeStarch!
