Hacking Club Mate "imatate"

Read about the end result here

Join me when I start brewing my first batch of Club Mate. Inspired by a podcast from chaos radio express on the topic "Hackerbrausen" (Hacker's soda, listen here) I want to try this by myself.

So far I have bought all the necessary ingrediends and tools to get started. And with the help from Jan (@janl) I can even carbonate the end result :)

When? Where?

Build ORB-SLAM2 on Raspberry Pi 3

Operating system: Ubuntu Mate 16.04

I use Ubuntu Mate instead of the usual Raspbian Jessie mainly because of the gcc version. ORB-SLAM2 requires C++11 support. Raspbian comes with gcc 4.9, which does not handle C++11 by default. That means you have to play around with some compiler flags in ORB-SLAM2's CMakeLists.txt to make it work. In contrast, Ubuntu Mate's gcc 5.4 handles C++11 naturally.

        return res;

Note: I configured this thinkfan setup for my old Thinkpad w520 on Ubuntu 17.10.

1. Install necessary programs

Install lm-sensors and thinkfan.

sudo apt-get install lm-sensors thinkfan
