Troubleshooting

Here are a couple of common issues and how to solve them.

Issue 1: ofxCvPiCam

If you run into compiler errors with the ofxCVPiCam library on RPi2. Its because the MMAL Libraries have changed slightly.

You can resolve these issues by following [this guide] (orgicus/ofxCvPiCam#3). Or for the short version just rename the libs folder in the ofxCvPiCam folder.

cd ~/openFrameworks/addons/ofxCvPiCam/
mv libs old-libs

Issue 2: ofxCv

There are some issues with ofxCv and later versions of openFrameworks. You can resolve these issues by checking out a different branch of the repo.

  • First remove the current installation of ofxCv:
cd ~/openFrameworks/addons
sudo rm -r ofxCv

  • Clone a fresh copy of ofxCv

    git clone https://github.com/kylemcdonald/ofxCv.git

  • Checkout branch according to oF version:

    • oF version < 0.9.8, checkout the VS2012-static branch.
    • oF version = 0.9.8, checkout stable.

Issue 3: glm:: errors in compile

Using oF 0.9.8 version's stable branch will negate the glm:: errors. If you were following oF's download guide previously, please remove the opensourceFrameworks folder as this is a fresh installation of oF.

git clone -b stable --single-branch https://github.com/openframeworks/openFrameworks.git

Follow the same instructions of building and compiling oF. No need to install dependencies for oF again if you had previously installed oF. Then follow the instructions the same instructions to build Footfall.
