A lot of compiler warnings that can easily fixed.

[ataweg]

For my project https://github.com/ataweg/CYD_ESP32_LVGL_EEZ I got a lot of compiler warnings that can easily fixed. Most of them are signed and unsigned issues. I attached two log files, For the first I used the esp-idf 5.3 default compiler settings and it produced a lot of warnings. It is just for reference. The second log file has some settings to reduce the warnings.

list( APPEND compile_options
   "-Wno-error=format="
   "-Wno-format"
   "-Wno-unused-variable"
   "-Wno-ignored-qualifiers"
)
list( APPEND cxx_compile_options
   "-Wno-missing-field-initializers"
   "-Wno-error=missing-field-initializers"
)

Has anybody got this working with esp-idf version 5.0.2+ ?

Try it again. I made it buildable for the community. It use esp-idf 5.3 and lvgl release/9.1.
Let me know if there are issues.
