no freertos/FreeRTOS.h in jpeg_decoder.c (IEC-420)

Answers checklist.

• I have read the component documentation ESP-IDF Components and the issue is not addressed there.
• I am using target and esp-idf version as defined in component's idf_component.yml
• I have searched the issue tracker for a similar issue and not found any related issue.

Which component are you using? If you choose Other, provide details in More Information.

esp_jpeg

ESP-IDF version.

v5.5.1

Development Kit.

any esp32 board with camera

Used Component version.

1.3.1

More Information.

I try to compile the camera example in the esp32-camera component and I get:

/opt/ucc/micros/esp32/esp-idf-v5.5.1/components/bootloader/subproject/managed_components/espressif__esp_jpeg/jpeg_decoder.c:8:10: fatal error: freertos/FreeRTOS.h: No such file or directory

Compilation failed because jpeg_decoder.c (in "bootloader" component) includes freertos/FreeRTOS.h, provided by freertos component(s).
However, freertos component(s) is not in the requirements list of "bootloader".
To fix this, add freertos to PRIV_REQUIRES list of idf_component_register call in /opt/ucc/micros/esp32/esp-idf-v5.5.1/components/bootloader/CMakeLists.txt.

I filed a bug report on the esp-idf repository but I was told to file it here.

So you want to use the jpeg library in your bootloader? But the bootloader build won't include FreeRTOS, that's why you see the build error.

Thanks for the answer. In fact I am not interested in using the jpeg library in the bootloader. However, when I try to compile the example program in esp32-camera, with the camera component installed, a folder
managed_components/espressif__esp_jpeg is created with jpeg_decoder.c in it. This is where the problem comes from.
When trying the same thing with esp-idf v5.4.2 I do not see the problem.

I'm also having the issue and might have some more insight on the matter. And maybe a solution.

In my case the library was getting pulled in even from an empty project. Running idf.py create-project test followed by idf.py menuconfig would create the managed_components/espressif__esp_jpeg folder and make it impossible to build with the following error:

ninja: build stopped: subcommand failed.
Compilation failed because jpeg_decoder.c (in "bootloader" component) includes freertos/FreeRTOS.h, provided by freertos component(s).
However, freertos component(s) is not in the requirements list of "bootloader".
To fix this, add freertos to PRIV_REQUIRES list of idf_component_register call in C:\espressif\esp-idf\components\bootloader\CMakeLists.txt.

Down the rabbit hole, I remembered that I followed this tutorial https://esp32tutorials.com/esp32-cam-esp-idf-live-streaming-web-server/ on how to build an esp32-cam project a couple days ago. The tuto suggested to add the content of this git https://github.com/espressif/esp32-camera in the components folder of the the esp-idf folder. It felt wrong but since I'm new to the whole idf toolchain, I went for it.

Turns out that removing this esp32-camera folder from the esp-idf components folder is solving the problem of getting esp_jpeg automatically referenced in all projects. I can now add the esp32-camera with the component manager (most probably as it should be) and build properly.
