compile issue with esp idf v5

[chaabanihoussem]

Hi

trying to build with esp32s3 esp idf v5 and doesn't build, it build with esp idf v4 but I need esp idf v5 since other libraries are only supported esp idf 5

here is logs for terminal output:

---

Hi, yes I'm using the last esp idf and the last version from your master branch, Did you manage to compile it with v5.x idf?

hi,

compilation tests are fine with esp-idf v5.x

I'm not sure why you get this error, but I'd focus on the cc1plus: some warnings being treated as errors and try to play with target_compile_options in CMakeLists.txt or CXXFLAGS in component.mk.

The -Wuninitialized error could be a false positive though, if you believe so you can still use #pragma GCC diagnostic ignored "-Wuninitialized" until this is fixed.

maybe there are some leftovers from a previously failed compilation?

or it could be a problem in your project folder, hard to say without seeing the actual project source :-)

it built now with esp idf v5

the linking issue is I had in the project directory "esp-idf" in the path and that caused issues finding object files

thank you for your help

I'm still gettig the same error(s) as described above. Errors start with [815/1224] Building CXX object esp-idf/LovyanGFX/CMakeFiles/__idf_LovyanGFX.dir/src/lgfx/v1/misc/pixelcopy.cpp.objFAILED: esp-idf/LovyanGFX/CMakeFiles/__idf_LovyanGFX.dir/src/lgfx/v1/misc/pixelcopy.cpp.obj.

I don't understand the solution of chaabanihoussem. Can someone please explain the esp-idf path issue? I'm using ESP-IDF v5.1.2
