A post for the blog series “Development Notes: Made Public”, where I post things it took me forever to Google for my own use, and perhaps someday yours.
Today I was hacking on my parrot drone and ran into a problem installing QRAR. What QRAR does is it detect QR Codes that your drone sees and decodes them for you-pretty useful if you’re looking to use QR Codes.
Unfortunately the install wasn’t particularly easy. Ran into a bug with Cairo. After much head banging, the fix turned out to be pretty simple.
The full install is just:
Download & install http://xquartz.macosforge.org/landing/ (it’s a dmg)
export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig brew install cairo ffmpeg npm install qrar
And you’re all set! Happy decoding!
