Strange compile errors after adding cmake component

[glrtheil]

I recently added parson as a component to my project, and suddenly I'm getting an error when I try to compile and flash within VS code.

I added a CMakeLists.txt file for the parson component

Code: Select all

set(ROOT_PATH
    ${CMAKE_CURRENT_LIST_DIR}/../../..
)

idf_component_register(
	SRCS ${ROOT_PATH}/libs/parson/parson.c
    INCLUDE_DIRS ${ROOT_PATH}/libs/parson
)

I added parson to the REQUIRES entry of idf_component_register of my main component (very end)

Code: Select all

idf_component_register(SRCS "${srcs}"
                    INCLUDE_DIRS "${include_dirs}"
                    REQUIRES app_update esp_https_ota bt littlefs console freertos nvs_flash coreMQTT azure-sdk-for-c azure-iot-middleware-freertos azure-iot parson
                    EMBED_TXTFILES ${project_dir}/server_certs/ca_cert.pem)

A couple things happen after this change. If there's ANY change to the git repository, like I make a commit, undo a commit, pop a stash, etc. it's almost as if the build is cleaned because it requires a full rebuild as if it's been cleaned even though it's not.

If I try to build/flash from the command pallette of vscode, I get this:

Failed to resolve component littlefs? That makes no sense. However, if I run shift+ctrl+B to build, which runs "idf.py build", it runs and compiles just fine. After I do this, THEN I can use the command palette to build and flash, even after I make minor code changes. If I make a change to something related to cmake, or make a git transaction, I have to force rebuild everything first.

If I remove parson as a component, everything goes back to normal. I can build from clean using command palette, and when I do a git commit or other git action, I'm not required to rebuild from scratch. It's really weird. Any ideas why this is happening?

Bumping this. Need to find a solution, as this affects other developers on the project.

Finally figured this out. In vs code, open settings UI. GO to Extensions > ESP-IDF. Ensure "Enable Idf Component Manager" is checked. Run full clean then rebuild using the command palette.
