Getting Started Step 3 about linphone-iphone

[bagage]

Did you try it? Running:

git submodule sync && git submodule update --init --recursive

I think I passed STEP 3 and now I a stucked with STEP 5.

I get the same error. This time that command line didn't work out. Any other suggestion to build the SDK?

"ERROR:root:Could not find prepare module: 'module' object has no attribute 'Target', probably missing submodules/cmake-builder? Try running:
git submodule sync && git submodule update --init --recursive"

How did you get the project?

Can you run ls and ls submodules/cmake-builder/?

Please reopen if still needed.
