I did the following work, but it was not included:

What's the problem? please

embeddedt commented 4 years ago

@TimonPeng You also have to patch several upstream files in order for the lvgl module to be built and linked. Take a look at the difference between lv_micropython and upstream MicroPython.

amirgon commented 4 years ago

To add to @embeddedt answer, the simplest way to use lvgl+micropython is to clone and build lv_micropython, which is a fork of Micropython v1.12 that incorporates lvgl.

TimonPeng commented 4 years ago

@embeddedt thanks for your reply, but i can't found lv_conf.h in https://github.com/lvgl/lv_micropython/tree/master/lib

TimonPeng commented 4 years ago

@amirgon thanks for your reply, but i used the same process to compile lv_micropython, but something wrong

Building with ESP IDF v3
find: ‘/root/esp-idf/components/json/include’: No such file or directory
find: ‘/root/esp-idf/components/json/port/include’: No such file or directory

Use the same process as micropython

amirgon commented 4 years ago

but i can't found lv_conf.h in https://github.com/lvgl/lv_micropython/tree/master/lib

lv_conf.h is part of lv_binding_micropython

i used the same process to compile lv_micropython, but something wrong

find: ‘/root/esp-idf/components/json/include’: No such file or directory
find: ‘/root/esp-idf/components/json/port/include’: No such file or directory

Did you checkout the correct esp-idf version as described in the README?

Did you get any other errors?
I believe that the two warnings you showed above can be ignored.

In general, to build lv_micropython you need to follow the instructions here.

TimonPeng commented 4 years ago

@amirgon yes, i used correct esp-idf version, my dockerfile here:

I don't think the errors you are getting are specific to lv_micropython. I suggeest you first try your dockerfile with upstream Micropython: instead of cloning lv_micropython.git, clone micropython.git, checkout v1.12, and see if you get the same errors.

There are many unusual things I noticed on your dockerfile:
