I am deploying my Rails 4.2 application in Redhat Linux 7.2 version. I cloned my project and when I run bundle install, I am facing Rmagick error. When I try to install it manually, I am facing errors as:

[root@ip-172-xx-xx-xxx Project2]# gem install rmagick -v '2.13.4'

Building native extensions. This could take a while... ERROR: Error installing rmagick: ERROR: Failed to build gem native extension.

current directory: /usr/local/rvm/gems/ruby-2.3.0/gems/rmagick-2.13.4/ext/RMagick

Can't install RMagick 2.13.4. Can't find MagickWand.h. * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/usr/local/rvm/rubies/ruby-2.3.0/bin/$(RUBY_BASE_NAME)

To see why this extension failed to compile, please check the mkmf.log which can be found here:

/usr/local/rvm/gems/ruby-2.3.0/extensions/x86_64-linux/2.3.0/rmagick-2.13.4/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /usr/local/rvm/gems/ruby-2.3.0/gems/rmagick-2.13.4 for inspection. Results logged to /usr/local/rvm/gems/ruby-2.3.0/extensions/x86_64-linux/2.3.0/rmagick-2.13.4/gem_make.out

I tried running:

`yum install ImageMagick` (Installed ImageMagick-6.7.8.9-15.21.amzn1.x86_64)
`yum install ImageMagick-devel` (It said 'No package found')

I tried thislink where we have to find MagickCore.pc, but I didn't found any MagickCore in my system.

Please help how to handle this issue.

ImageaMagick, as different other larger projects, installs the pkg-config pc.-files of project-internal libraries in the subdirectory specific to the project.

In case of ImageMagick, this is usually the path /usr/lib/imagemagick6/pkgconfig/ instead of /usr/lib/pkgconfig/.

An easy fix is provided by adding the directory to the PKG_CONFIG_PATH environment variable via

$ export PKG_CONFIG_PATH=PKG_CONFIG_PATH:/usr/lib/imagemagick6/pkgconfig

A different approach is using the CLI-option --with-path for pkg-config. So in your case:

$ pkg-config --with-path=/usr/lib/imagemagick6/pkgconfig/

However, this means touching the pkg-config command of your package installation, which may be not possible in the mentioned case.
