Current Uno v1.12 works with CMake 3.6.4111459, but has the problem you’re describing when trying to build using newer CMake. From your log it looks like you’re building using a newer CMake.
To fix this you can either,
- Add
ninja.exe
to PATH. It’s included in Android CMake and the location is likely%LOCALAPPDATA%\Android\sdk\cmake\3.10.2.4988404\bin
. - Or, make sure you only have CMake 3.6.4111459 installed.
3.6.4111459
should be the only sub-directory found under%LOCALAPPDATA%\Android\sdk\cmake
.
The upcoming Uno v1.13 will work with the new CMake version out-of-the-box, and will be released in about two weeks I think.
