I had few problems installing GraphicsMagick on my OSX system. Installation via brew wasn't working the right way.
So, first I un-installed the brew versions just to make sure:
sudo brew uninstall --force graphicsmagick
sudo brew uninstall --force imagemagick
And next, here is a 101 way of getting this running:
- Install LibJPEG
- Install LibPNG
- Install LibTIFF
- Install GraphicsMagick
The above links from Patrick Bougie are straight forward and seemed to work perfectly.
Note, I had to explicitly set the symbolic link to make my fish shell recognize. Some problem with my PATH I guess.
sudo ln -s /usr/local/graphicsmagick-1.3.21/bin/gm /usr/sbin/gm
