Installing Pillow/PIL on Mavericks

Question

I'm getting a strange error when trying to install Pillow using pip/easy_install:

cc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -g -Os -pipe -fno-common -fno-strict-aliasing -fwrapv -mno-fused-madd -DENABLE_DTRACE -DMACOSX -DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -DENABLE_DTRACE -arch x86_64 -arch i386 -pipe -DHAVE_LIBJPEG -DHAVE_LIBZ -DHAVE_LIBTIFF -I/System/Library/Frameworks/Tcl.framework/Versions/8.5/Headers -I/System/Library/Frameworks/Tk.framework/Versions/8.5/Headers -I/usr/local/Cellar/freetype/2.5.3/include/freetype2 -I/private/var/folders/c_/r7sp373509jdb6_1xmmzvl9c0000gn/T/pip_build_tills13/Pillow/libImaging -I/System/Library/Frameworks/Python.framework/Versions/2.7/include -I/usr/local/include -I/usr/include -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c _imaging.c -o build/temp.macosx-10.9-intel-2.7/_imaging.o

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

error: command 'cc' failed with exit status 1

I've read all the symlink answers, I've installed commandline tools, nothing seems to be working. I always get that error.

Answer 1

I solved that problem the following way. Propably has something to do with todays Mavericks commandline tools update. Try adding following to the terminal before executing pip install:

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

Answer 2

Run this command in the terminal:

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install pillow

More info:

The compiler that comes with Xcode 5.1 treats unknown passed parameters as errors.

We're telling it to ignore those "errors"

Answer 3

In addition to @jussi, I had to open terminal and do the following:

    sudo bash
    export CFLAGS=-Qunused-arguments
    export CPPFLAGS=-Qunused-arguments

Only then could properly run 'pip install pillow'

If I didn't run this using a superuser prompt, I would get the following error:

    error: could not create '/Library/Python/2.7/site-packages/PIL': Permission denied

I'm running OSX 10.9.2 with the March 2014 Command Line Tools installed. I also have Homebrew installed if that makes a difference.

Answer 4

Check out brew http://brew.sh

brew tap Homebrew/python
brew install pillow

Answer 5

None of these solutions worked for me. I finally got it installed with help from this post:

I find the same issue trying to build MySQLdb with the latest Xcode and OS updates. Here is a work around that involves removing the flag from the python installation.

In /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_sysconfigdata.py are several places where the -mno-fused-madd flag is set. If you edit this file and remove all of the references to that flag your compilation should work. You need to delete the corresponding _sysconfigdata.pyc file as well - at least on my system that file did not automatically get rebuilt. Note that have to use root access to make those changes.
