I'm using Homebrew to install ROS - Hydro on my 10.9 Mac. While using ROS' wiki for installing hydro, 2.1.2 causes an error specifically pertaining to installing PIL. I know such has been replaced with Pillow, and have already used such before. My question is, how do I get ROS to just use Pillow instead of PIL
I have no clue how interchangeable PIL and Pillow are, so no idea how easy it would be to make the code depending on PIL use Pillow. I think your easier bet is just installing PIL.
I assume you are getting a freetype related compilation error? This has been discussed before, you will likely be successful with the following sequence of commands:
ln -s /usr/local/include/freetype2 /usr/local/include/freetype
pip install -U PIL --allow-external PIL --allow-unverified PIL
rm /usr/local/include/freetype
Update: According to William in the comments below this is a better way to work around the freetype issue:
CFLAGS="-I/usr/local/include/freetype2" pip install -U PIL --allow-external PIL --allow-unverified PIL
EDIT: you might need sudo pip instead of pip
We ran into issues where ogre would not compile with that symbolic link, it somehow created a circular or incorrect include problem with freetype. I had previously done something like `CFLAGS="-I/usr/local/include/freetype2" pip install ...` and that allowed pip to build `PIL`, without permanently changing the system. I'm not sure that is right, but I'll just look around on the internet for that.
Here: https://github.com/osrf/homebrew-simulation/issues/6#issuecomment-38644605 You have to include the X11 version of freetype in the `CFLAGS`.
Is there any advantage of `CFLAGS= ... pip install` vs my suggestion to create and remove the link? rosdep should maybe be capable of customizing the pip command. Something like `prepend_install: 'CFLAGS="-I/usr/local/include/freetype2"'` or `install_env: {CFLAGS:"-I/usr/local/include/freetype2}`
