IDF Component Manager

[sve-jviParticipant]

Hi,

In my application I need to include a dependency to a component from the espressif repository: https://components.espressif.com/

When I build the project, the toolsuite detects the dependency but cannot update the component because it says that the component manager has not been enabled.

CMake Warning at C:/SysGCC/esp32/esp-idf/v4.4.1/tools/cmake/build.cmake:482 (message):
“idf_component.yml” file was found for components:
C:/Users/user/Documents/Proyectos/ESP32/Firmware/Prue/P29/mb_master/main
However, the component manager is not enabled.

What is the procedure to enable the Component Manager?

I use Visual Studio 2019 16.11.17 / VisualGDB-5.6R6-4622 / Toolchain 8.4.0/8.1.0/r9 / ESP-IDF v4.4.1

Thank you very much.

This looks like an error coming from the ESP-IDF build system and not something specific to VisualGDB. Please refer to the ESP-IDF documentation for more details on it.

If you can build the same project outside VisualGDB, but not with VisualGDB, please follow the troubleshooting instructions here to get it working.

Yes, I understand that this is not a VisualGDB issue, but I am asking how I can configure the Espressif toolsuit that comes with VisualGDB so that the component manager is enabled.

In the official Espressif IDE we have the “ESP-IDF 4.4 CMD” where we can work from the command line.

In this CMD we can execute the following command to enable the component manager:

pip install idf-component-manager –upgrade

And in the configuration of the project with dependencies developed with the Espressif-IDE we can define IDF_COMPONENT_MANAGER environment variable:

My question is how can I build a project that has dependencies?

Thank you very much.

hi @sve-jvi,

you may be interested in this esp-idf-v5 issue on this forum, and Espressif idf-installer issue #143 on GitHub.

I’m certainly interested if you make any progress.

I have already found the solution.

On the website idf-component-manager it says:

Starting ESP-IDF v4.4 the idf-component-manager package is installed by default and no extra action is necessary.

Since I use v4.4.1 I don’t need to run the pip command.

To enable the component manager in the project configuration phase, you must add the following variable in the CMakeLists.txt of the project root:

set(ENV{IDF_COMPONENT_MANAGER} “1”)

In this way, in the configuration phase, when the idf_component.yml file is found in the main component, the dependency is executed and the referenced component is downloaded:

Solving dependencies requirements
Updating lock file at C:/Users/user/Documents/Tmp/espressif/mb_slave\dependencies.lock
Processing 2 dependencies:
[1/2] espressif/esp-modbus (1.0.4)
[2/2] idf (4.4.1)
— DEBUG: Use esp-modbus component folder: C:/Users/user/Documents/Tmp/espressif/mb_slave/managed_components/espressif__esp-modbus.

This is very important because the freemodbus component has been moved to a separate esp-modbus repository from v5.0.

Thanks for sharing this. It indeed looks like a change in ESP-IDF structure and not something VisualGDB would handle automatically. That said, if you do not want to edit the CMakeLists files manually, you can always specify the extra environment variables via the VisualGDB GUI as shown below:
