ESP32 Forum

I'm trying to use expressif idf v4.1.2 to build a project I've inherited, like this:

docker run --rm -v f:\projects\myproject\firmware :/firmware -w /firmware -it espressif/idf:v4.1.2

That command finds the espressif idf container tagged v4.1.2 and creates an image linked to my firmware folder.

When I do
idf.py build

it gets only to line 5 of step 2, and fails on the command 'rollup':

[2/102] Generating rofs_data.c

I don't know where rollup and uglifyjs are supposed to come from. Is there a problem with my project, or is the problem with the v4.1.2 docker container?

Sounds like the project you have there has some custom magic in its makefiles in order to invoke those tools. From what I'm aware, they're not standard for ESP-IDF.
