Updating the wiki

[nahakiole]

The editing of the wiki hasn't been enabled and I just compiled and run the library on our pepper and had some issues while doing it.

Would it be possible to add my issues and their solutions to the wiki, so the next people trying it could profit from it?

My issues in particular were:

• Not using Ubuntu 14.04, so I'd add a notice recommending it, as I tried Ubuntu 20.04 which didn't work and also caused issues with Python 2.7
• Issues with compiling opencv not finding dependencies and having to link them manually

  sudo -i
  mkdir /usr/include/ffmpeg
  cd /usr/include/ffmpeg
  ln -sf /usr/include/x86_64-linux-gnu/libavcodec/*.h ./
  ln -sf /usr/include/x86_64-linux-gnu/libavformat/*.h ./
  ln -sf /usr/include/x86_64-linux-gnu/libswscale/*.h ./

• Installing the dependencies and some missing libraries so I'd add the apt-get install commands

  sudo apt-get install unzip cmake build-essential git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev 

• Having to compile Python 2.7.18 and setting up pip for it as Python 2.7.8 which was bundled with Ubuntu 14.04 couldn't install dependencies with pip because of SSL issues.
• Setting up qibuild to build binaries for linux by providing example commands and configuring the build directory

  qitoolchain create naoqi-sdk ../naoqi-sdk-2.5.7.1-linux64/toolchain.xml
  qibuild init
  vim qibuild.xml
  qibuild config --wizard
  qibuild add-config naoqi-sdk --toolchain naoqi-sdk
  qibuild configure -c naoqi-sdk --release
  qibuild make -c naoqi-sdk

• Some time was spent with this issue: https://github.com/LCAS/spqrel_navigation/issues/6 So I think the error should be added to the instructions with the fix.
• I also thought about creating a docker image for compiling the application so people would have less issues, would that be of interest for you?
• Would it be an idea to provide compiled binaries, so people wouldn't need this setup to use the library?
• Also which is the latest stable version? Still 1.2?

Also thank you so much for creating the library, it was really cool that our pepper can now drive through our laboratory. 🤖 😄

Although we still had some issues with walls which weren't connected to the floor as the ultrasound sensor seems to think there isn't a wall. But nothing that can't be fixed with cardboard and some tape 😄
