cmake error (IDFGH-11271)

[epicdenver1]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

i have a fresh install of 5.2-dev and this code has worked before on a windows based visual studio machine. i am using a tinly ml conversion of a TensorFlow lite model to try and get it to work on my esp32-s3.
bellow is my cmake file
CMakeLists.txt
i am aware that in 5.0 updating to 5.1 they changed the way idf_component_register changed but this was not an issue on 5.11 on windows. the other files such as the project file and model will be attached bellow. i have been working on this for 8 hours and have been racking my brain; any expertise even if it makes me look dump is appreciated.
app_main.txt
handrecognition_coefficient.txt
i converted the c++ format of the above two files

thanks in advance -ryan

Hi @epicdenver1, would you mind sharing the actual error message? "cmake error" can mean a lot to us, we need more details to trace down the error.

Thank you!

[epicdenver1]

this is the error, i get the same one with both idf v 4.4.4 , 5.2 dev , and 5.1.1
/home/ryan/esp-idf-v4.4.4/tools/check_python_dependencies.py:12: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html

i have ninja installed and double checked before i made this post

Looks like you are trying to run idf.py build in the main subdirectory, not in the project directory?

idf_py_stdout_output_1924.txt
i grabbed the wrong file my bad

Over here:

if(${IDF_TARGET} STREQUAL "esp32")
    set(links "-L ${CMAKE_CURRENT_SOURCE_DIR}/../../../lib/esp32")
elseif(${IDF_TARGET} STREQUAL "esp32s2")
    set(links "-L ${CMAKE_CURRENT_SOURCE_DIR}/../../../lib/esp32s2")
elseif(${IDF_TARGET} STREQUAL "esp32s3")
    set(links "-L ${CMAKE_CURRENT_SOURCE_DIR}/../../../lib/esp32s3")
elseif(${IDF_TARGET} STREQUAL "esp32c3")
    set(links "-L ${CMAKE_CURRENT_SOURCE_DIR}/../../../lib/esp32c3")
endif()

target_link_libraries(${COMPONENT_TARGET} ${links})

you are only specifying the directory where to search for the pre-compiled libraries, but you aren't actually linking any specific library. Hence,

c:/espressif/tools/xtensa-esp32s3-elf/esp-12.2.0_20230208/xtensa-esp32s3-elf/bin/../lib/gcc/xtensa-esp32s3-elf/12.2.0/../../../../xtensa-esp32s3-elf/bin/ld.exe: esp-idf/main/libmain.a(app_main.cpp.obj):(.literal._ZN2dl6TensorIsE12copy_elementERS1_b[_ZN2dl6TensorIsE12copy_elementERS1_b]+0xc): undefined reference to `dl::tool::copy_memory(void*, void*, int)'

c:/espressif/tools/xtensa-esp32s3-elf/esp-12.2.0_20230208/xtensa-esp32s3-elf/bin/../lib/gcc/xtensa-esp32s3-elf/12.2.0/../../../../xtensa-esp32s3-elf/bin/ld.exe: esp-idf/main/libmain.a(app_main.cpp.obj):(.literal._ZN2dl5layer7SoftmaxIsfLi1ELb0EED5Ev[_ZN2dl5layer7SoftmaxIsfLi1ELb0EED5Ev]+0x0): undefined reference to `dl::layer::Layer::~Layer()'

some of the references from main component to the pre-compiled library don't get resolved.

thanks for that, how do i fix that, those are from the guide i was using to develop this model but if you have an idea i'm willing to give it a shot. thanks

[igrr]

Could you please link to the guide you are reading?

xtensa-esp32s3-elf/bin/ld.exe: cannot find -ldl: No such file or directory

Can you check if there is libdl.a in the directory you have specified in CMakeLists.txt, i.e. <project_dir>\main\..\..\..\lib\esp32s3\libdl.a?

(If it is in some other place, edit your CMakeLists.txt to pass the correct directory to the linker.)

[epicdenver1]

if i had that library in my /main or in the directory how would i edit the cmake file

@epicdenver1 I checked with the creator of the tutorial. Unfortunately, the example is only made for IDF v4.4. It won't work out-of-the-box on IDF v5.2.
