Hi
I'm using the example code provided here (https://github.com/espressif/esp-idf/tr ... idf_as_lib) to build my application.
After building I want to run idf.py size , idf.py size-components. Both of them return error.

Code: Select all

udayms@pc:~/esp/esp-idf-v5.1.1/examples/build_system/cmake/idf_as_lib ((no branch))$ idf.py size-components 
Executing action: size-components

ninja: error: unknown target 'size-components'

I did look into other example and figured out that '.map' file is needed.
As I'm new to CMake , I couldn't generate the .map file even after spending couple of hours on it.

It would be helpful if someone guide me to generate .map file or provide steps to enable idf.py size-components

I was able to generate a map file with following additions

Code: Select all

set(idf_size ${python} -m esp_idf_size)
set(mapfile "${CMAKE_BINARY_DIR}/${CMAKE_PROJECT_NAME}.map")
target_link_options(${elf_file} PRIVATE "-Wl,--Map=${mapfile}")

and enable size-components command by

Code: Select all

add_custom_target(size-components
    COMMAND ${CMAKE_COMMAND}
    -D "IDF_SIZE_TOOL=${idf_size}"
    -D "IDF_SIZE_MODE=--archives"
    -D "MAP_FILE=${mapfile}"
    -D "OUTPUT_JSON=${OUTPUT_JSON}"
    -P "${idf_path}/tools/cmake/run_size_tool.cmake"
    DEPENDS ${mapfile}
    USES_TERMINAL
    VERBATIM
)

Now I got a new error

Perhaps this is what you are missing:

Code: Select all

        # Add this symbol as a hint for esp_idf_size to guess the target name
        target_link_options(${project_elf} PRIVATE "-Wl,--defsym=IDF_TARGET_${idf_target}=0")

Thanks ESP_Roland
This solved my issue
