Raspberry pi Installation

[efbick]

I am having trouble building and installing upm on raspbian. I'm thinking its because im missing a few modules but I couldn't find some of them to install.

Hi @efbick, try specifying your architecture when generating the makefiles with cmake like this: cmake -DCMAKE_CXX_FLAGS:STRING=-march=armv6 ..

You don't have to worry about missing modules, the sensor modules that have a dependency on them simply won't get built.

Thanks that seemed to work for installing. I attempted to run one of the examples for the mpu9250 and it can't seem to find it. Not sure what happened. Attached the error below.

Hi @efbick. You can run find /usr -name "_pyupm_mpu9150*" to check if the .so files have been installed in a different location. There's a chance they were placed under site-packages instead of dist-packages as expected on your system.

Either move them or let python know about it by setting the PYTHONPATH variable.
