Hi,

I'm currently trying to bring up an esp32cam board using pio with framework=espidf.

I'm setting up the project according to the guide here https://github.com/espressif/esp32-camera. I took into account all the mentioned hints to bring it up in this constellation. But I'm ending always with the linking errors below:

Hi, have you given this one a try? https://randomnerdtutorials.com/esp32-c ... duino-ide/

"undefined reference" in general means the include files (in this case for the camera), are being found, but the actual c/c++ source code files of the referenced libraries (in this case for the camera) are not being compiled, ie not being considered by the build system (in this case platformio). Hence you must have skipped something or typed something either wrong or in the wrong location.

actually, after closer inspection of your logs, platformio is correctly picking up the source files and compiling them. It simply isn't finding the specific functions it is looking for. This hints that you might have cloned something wrong, such as the wrong tag/branch.

Or more probably, you've configured sdkconfig wrong, or used an incorrect sdkconfig, one that doesn't take the camera into consideration. After you add/remove/modify libs, including esp32-camera, you have to regenerate the sdkconfig so it shows you the section for the camera. Make sure you configure that correctly. If you don't see it, then you definately need to update your sdkconfig. Try deleting it first, then redo menuconfig.

after some research, I can assure you all the functions that are not being found, are in the files "target/esp32/ll_cam.c" and "target/xclk.c" in your esp32-camera folder. So those files specifically are not being picked up. I don't know why. You'll have to find a way to get the build-system to pick them up and compile them. This might not be a mistake on your part, rather an unexpected difference in behavior between various esp-idf and platformio versions.

But if you don't have those folders/files in your esp32-camera folder, then you definately cloned wrong.

Or, if you cloned right... then you might have inadvertently changed the value of IDF_TARGET. If you look at CMakeLists.txt within esp32-camera, you'll notice it includes those specific folders/files, but only if IDF_TARGET equals "esp32" or "esp32s2" or "esp32s". So you probably changed the value incorrectly to include the word "cam". In that case find out what it's exact value is, and modify the corresponding line that says:

Code: Select all

if(IDF_TARGET STREQUAL "esp32")

I have tried the following but until now without success.

1. When I asked the question first I have used pio and selected the "AI Thinker ESP32-CAM" board for the project. I don't cloned the esp32-camera from github I only copied the take_picture.c in then main file and used

Code: Select all

[env]
lib_deps =
  esp32-camera
and menuconfig for the camera also worked using Kconfig.projbuild from github. But I was getting the errors mentioned in my first post.

2. Then I started using the "Espressif ESP32 Dev Module" board in pio and cloned the esp32-camera to the project lib dir as described on github:

Code: Select all

cd $project\lib
git submodule add -b master https://github.com/espressif/esp32-camera.git
and added in platform.ini file

Code: Select all

build_flags =
   -I../lib/esp32-camera
I setup the Kconfig.projbuild and configured the camera and PSRAM in menuconfig. It compiles with the same errors as in my first try:

Code: Select all

The terminal process "C:\Users\grobot\.platformio\penv\Scripts\platformio.exe 'run', '--environment', 'esp32dev'" terminated with exit code: 1.

Terminal will be reused by tasks, press any key to close it.
It compiles all files in the /conversions, /driver and /sensors directories but not xclk.c and ll_cam.c from the /target directory.
I've played around with the CMakeLists.txt in the /lib/esp32-camera directory but it seems that it isn't recognized by pio during build because I've renamed it and compiling worked the same.

What I don't understand is from where the build process is getting the infos how to compile /lib/esp32-cam?

I was able to compile the esp32cam code by adding the target directory in the library.json file under build -> srcFilter.
At the moment I'm not able to test the code on a module. But I hope it will work...

Code: Select all

I was finally able to run the demo code on a ESP32-CAM module with the following setup:

- in pio I've used the Espressif ESP32 Dev Module and Espressif IoT Development Framework
- cloned https://github.com/espressif/esp32-camera.git to the lib folder in the project
- in platform.ini added build_flags = -I../lib/esp32-camera
- added Kconfig.projbuild and configured PSRAM and camera as described on https://github.com/espressif/esp32-camera
- deleted the folders /esp32s2 and /esp32s3 (not used and removed the errors for tjpgd.h)
- in library.json in the lib folder added "+<target>" under srcFolder

The complete library.json

Thank you so much rotscher.
I was having SO much trouble with this recently. Your instructions got me 99% of the way there.
Although I deleted the esp32s2 and esp32s3 directories under esp32-camera\lib\esp32-camera\target, I also had to remove esp32-camera\lib\esp32-camera\target\tjpgd.c because it seemed that Platformio(?) wanted to compile tjpgd.c even though I had "esp32" selected in skdconfig.esp32cam
CONFIG_IDF_TARGET="esp32"
CONFIG_IDF_TARGET_ESP32=y
