Question

I am having issue while trying to install "rmagick" gem on centos. Following is the output I am having. Can anyone please help me identifying what package I am missing? I have installed all mentioned another stack-overflow thread: RMagick install error

brew link --force imagemagick@6
gem install rmagick

This is the correct answer if you are using homebrew and having issues with ImageMagick7. – mindtonic May 24 '17 at 18:54

The error message says:

Package MagickCore was not found in the pkg-config search path.
Perhaps you should add the directory containing `MagickCore.pc'
to the PKG_CONFIG_PATH environment variable
No package 'MagickCore' found

It seems you missing no package at all, you just have to tell pkg-config where to find the MagickCore.pc file to build the extension. If you have installed the package ImageMagick-devel using yum the file should be inside the directory /usr/lib/pkgconfig or /usr/lib64/pkgconfig (depending on your architecture). Check with this command (from now I assume you are on a amd64 machine, if it's not the case replace lib64 with lib):

$ find /usr/lib64/pkgconfig -name MagickCore.pc

If the file is there you just have to install rmagick with this command:

$ PKG_CONFIG_PATH='/usr/lib64/pkgconfig' gem install rmagick

Thanks. your suggestion worked. However, I am getting another output now(please check the edited question details). I am not sure what to do with the "Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details." . Also, do I need to install the development versions mentioned in the output? – Rana May 27 '13 at 15:12
Hi, yes, I just confirmed that do have this glibc-headers lib installed. any other clue? – Rana May 27 '13 at 19:44
added the output of mkmf.log file above. Please check if you can find any clue. I am new at these and linux too, so a lot lost, outputs are less meaningful to me :( . Also, if you can give me a descriptive guide link to install RMagick that I can follow from start again, it will be of great help too. – Rana May 28 '13 at 09:47
no, I didn't compiled any package from source. I have always installed the packaged libraries either using "yum install" or "gem install" . The answer on this question: http://stackoverflow.com/questions/14355798/gem-install-error-with-rmagick?rq=1 , do you think that can be a similar case for me too? incompatible version of rmagick with imagemagick? – Rana May 28 '13 at 14:35

On Ubuntu 16.04 this is now PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16:$PATH" PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig gem install rmagick -v '2.13.2' – werkshy Mar 18 '16 at 15:13

The problem is, as the error puts it,

Package MagickCore was not found in the pkg-config search path

The solution is also suggested there:

add the directory containing MagickCore.pc to the PKG_CONFIG_PATH environment variable

So,

Find MagickCore.pc location:
```
sudo find / -name MagickCore.pc
```
If it is not found, probably ImageMagick is not installed on your system — then install it (Google how to do it, as it depends on the OS)
Save it to the ENV var like that (make sure to put the path found in step 1):
```
PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig
```
Retry installing RMagick

The `directory containing` means you have to remove filename to make it work. So `PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig`. – sekrett Feb 19 '18 at 13:47
Definitely! Thanks, @sekrett – Sergey Pedan Mar 15 '18 at 14:06

For Mac with Brew, simply..

brew install imagemagick

Then gem install imagemagick will work smoothly.

It doesn't look like you're missing any packages. The error message is important:

Perhaps you should add the directory containing `MagickCore.pc' to the PKG_CONFIG_PATH environment variable

Several of the answers on this superuser duplicate give good advice.

On debian (unstable) the correct packages needed to resolve this error were libmagickcore-6.q16-dev, imagemagick and libmagickwand-6-headers

I found them by using apt-file search MagickCore.pc and apt-file search MagickWand.h

For windows users who run into this, and are 100% psotive that they have the devkit installed:

When installing, you will be presented this prompt

Choosing 1 is not enough. Just press enter (1 & 3) and that will install the devkit properly.
