Build error for ESP32

Open AlixANNERAUD opened this issue 7 months ago • 0 comments

Hello, apart from the latest commits that have completely broken the build, I am unable to compile lvgl :

error: failed to run custom build command for `lvgl-sys v0.6.2 (/home/alix_anneraud/Git/Personnel/Xila/lv_binding_rust/lvgl-sys)`

Caused by:

I have tried some solutions suggested here, which help to get rid of some error messages. However, it seems to end up being a mess because, in the case of the ESP32, the $LIBCLANG_PATH environment variable is set to ESP32 clang toolchain, which means that for the native compilation part (as used by lvgl/build.rs), bindgen / libclang no longer seems able to use the correct version of clang (it uses the ESP32 version instead of the native / host one). Maybe you should avoid to use lvgl-sys in lvgl build script ?
