ImageMagic installed via Homebrew doesn't work

[jkamenik]

I use a Mac, and homebrew for many packages including ImageMagick. I noticed a very annoying issue that I had to work around. Homebrew symlinks to /usr/local/bin and /usr/local/include. For example: /usr/local/include/ImageMagick -> /usr/local/homebrew/.../ImageMagick. This works fine with most libraries that need imagemagick since Magick-config produces the correct paths to the symlinks and the compilers just follow the sym links.

The rmagic gem compile does not seem capible of following symlinks and therefore cannot find /usr/local/include/wand/MagickWand.h which is there.

$ gem install rmagick

My solution was to install ImageMagick via https://github.com/maddox/magick-installer/blob/master/magick-installer.sh, which doesn't use symlinks. Without symlinks things work fine.

Looks like a candidate for closing, @mmaiza.

Despite trying everything and following all StackOverflow recommendations, I can't install rmagick. Ugh. Help!

Aha! Reinstalling pkg-config FINALLY fixed my problem!!! http://stackoverflow.com/a/23957018/2175188

Reinstalling pkg-config didn't help.

Why would it even check for old version of imagemagick?

[RomanKapitonov]

Nevermind, I had ruby installed under previous version of Mac OS X. Reinstalling ruby fixed the issue. just run rvm reinstall [you-version-of-ruby] and you are done.

[Shekharrajak]

May be you are installing ImageMagick version 7.x.x which will generate different folder names in your usr/lib/local/include/ImageMagick7.x.x folder.

In ImageMagick6.x.x version we have magick, wand named folders, where in ImageMagick7.x.x version have named this MagickCore , MagickWand . So this updation is causing the problem in some gem installation like here. Which is using
magick/some_header.h or wand/some_header.h (Means they are not updated with the new 7.x.x ImageMagick version).

That's why we are getting this error :

    checking for outdated ImageMagick version (<= 6.4.9)... no
    checking for presence of MagickWand API (ImageMagick version >= 6.9.0)... no
     .... 
    checking for wand/MagickWand.h... no

and in log file something like this :

error: 'MagickCore/method-attribute.h' file not found
#include "MagickCore/method-attribute.h"
         ^

Solution

Install the ImageMagick6.x.x version in your system from the official site : https://www.imagemagick.org/download/ and install it using this commands(after extract zip/tar) :

./configure
make 
make install

Then do

gem install rmagick

It will work.

You could also install imagemagick 6 with homebrew

brew install imagemagick@6
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opt/imagemagick@6/lib/pkgconfig

[tungvn]

Confirm solution of @sragu is worked. But I lost this env variable each time I log out/restart or sthg like that.
Solution is add the above line into ./bash_profile:

echo "export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opt/imagemagick@6/lib/pkgconfig" >> ~/.bash_profile
