Custom type for telemetry channel not working

[aliaga17]

I implemented a custom type for my fprime project exactly as it is done in the mathcomponent tutorial (including all the creation of the CMakeLists.txt file and modifying the project.cmake accordingly). I now want to declare a telemetry channel that uses such type, but the component fpp file is giving me an error saying "no type 'CalState' was found". why could this be?

In MathTypes.fpp:

module Components { 
    @ ADCs calibration states
    enum CalState {
        CAL @< Calibrated
        NOTCAL @< Not Calibrated
  }
}

In component.fpp:

module Components{
    ...
    @ Telemetry channel to report calibration states of the ADCs
            telemetry AdcsCalibration: CalState
    ...
}

Are you able to share your repository? Otherwise it'll be hard to debug. This looks correct to me... Or at least share the CMakeLists.txt files content ? Does adding the following to your component CMakeLists.txt fix the issue:

set(MOD_DEPS
    Types_MathTypes # or fix to correct module name if you changed it
)

I added the line you suggest and I get the following error:

CMake Error at lib/fprime/cmake/target/build.cmake:82 (add_dependencies):
-- Generating done (0.2s)
  The dependency target "Types_TeralinkTypes_Components" of target
  "Components_rfsoc" does not exist.

My file structure for the new types looks like this:
Project
|...
| Types
| | CMakeLists.txt
| | TeralinkTypes.fpp

Types CMakeLists.txt:

set(SOURCE_FILES
  "${CMAKE_CURRENT_LIST_DIR}/TeralinkTypes.fpp"
)

register_fprime_module()

Component CMakeLists.txt (rfsoc is the component):

# Include project-wide components here

# add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/MyComponent")
add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/rfsoc/")

set(MOD_DEPS
    Types_TeralinkTypes 
)

Project.cmake:

# This CMake file is intended to register project-wide objects.
# This allows for reuse between deployments, or other projects.

add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/Components")
add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/TeralinkPayload/")
add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/Types/")

MOD_DEPS need to be prior to the component's register_fprime_module() call and only there. In the rfsoc/Cmakelists.txt not in the Components/CMakelists.txt file
The name of the module is by default the path to the CMakeLists.txt file, so it would likely be Types and not Types_TeralinkTypes

[thomas-bc]

Try in project.cmake to move Types/ up so it appears prior to Components/ which needs it, and remove the MOD_DEPS

# This CMake file is intended to register project-wide objects.
# This allows for reuse between deployments, or other projects.

add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/Types/")
add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/Components")
add_fprime_subdirectory("${CMAKE_CURRENT_LIST_DIR}/TeralinkPayload/")

Worked! Tysm!
