Imagick solution when unable to install

Sometimes installing Imagick will prompt:

"Configure:error:not found. Please provide a path to Magickwand-config or Wand-config program. "

This is because only the "ImageMagick" is installed and the "Imagemagick-devel" is not installed, the Imagemagick-devel is installed through the following command line, and then the previous steps to install Imagick will be done.

Yum Install Imagemagick-devel

discuz! ImageMagick settings on X

Check with the convert–version command to see if OpenMP appears, because the machine does not support OpenMP, and needs to be recompiled./CONFIGURE–DISABLE-OPENMP, and then install.
