==> ./configure --disable-osx-universal-binary --without-perl --prefix=/usr/local/Cellar/imagemagick/6.7.7-6 --enable-shared --disable-static
==> make install
Error: The linking step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link imagemagick'
==> Summary

linking after bad linking in install:

ostaptan:wand ostap$ brew link imagemagick

Linking /usr/local/Cellar/imagemagick/6.7.7-6...

Error: Could not symlink file: /usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/wand/wand-view.h

Target /usr/local/include/ImageMagick/wand/wand-view.h already exists. You may need to delete it.

To force the link and delete this file, do:
  brew link -f formula_name

To list all files that would be deleted:
  brew link -n formula_name

How to link??? what to do?? Can't find answers anywhere!

Answer 1

As suggested in the brew link output, try

brew link -f imagemagick

This should clean up old links in /usr/local/include/ImageMagick/, and then link the files required to complete the installation.

If this doesn't work check that your user has permission to write to /usr/local/include/ImageMagick/*.

Answer 2

After hours and hours of trying the only thing that worked for me was:

sudo brew link --overwrite imagemagick

(Also requires /usr/local/bin/brew to be chowned to root)
