在Ubuntu 10.04上使用graphicsmagick安装rmagick 2.13.1
我之前有一个与ImageMagick一起使用的rmagick gem安装。 从禁用OpenMP的源安装ImageMagick。 这种安装工作没有任何障碍。 但是我试图卸载rmagick和ImageMagick，以便我可以使用与GraphicsMagick一起使用的版本。
所以我从源代码安装了GraphicsMagick并再次禁用了OpenMPfunction。 但是，当我安装rmagick时，我得到以下内容：
Building native extensions. This could take a while... ERROR: Error installing rmagick-2.13.1.gem: ERROR: Failed to build gem native extension. /usr/bin/ruby1.8 extconf.rb --build-opts --with-graphics-magick checking for Ruby version >= 1.8.5... yes checking for gcc... yes checking for Magick-config... yes Warning: Found a partial ImageMagick installation.

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/bin/ruby1.8 我已经尝试过：
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
并检查文件夹pkgconfig的内容：
freetype2.pc GraphicsMagick.pc GraphicsMagick++.pc GraphicsMagickWand.pc libpng15.pc libpng.pc
我在这里想念的是什么？
你有没有尝试在stackoverflow或谷歌上搜索这个问题？ 安装libmagickwand-dev后再尝试安装。
apt-get install libmagickwand-dev
开发包非常有用
sudo apt-get install libmagickcore-dev libmagickwand-dev
对我来说帮助了以下： sudo apt-get install imagemagick libmagickcore-dev
