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,以便我可以使用适用于GraphicsMagick的版本。
所以我从源代码安装了GraphicsMagick并再次禁用了OpenMP功能。但是,当我安装rmagick时,我得到以下内容:
Building native extensions. This could take a while...

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/bin/ruby1.8
我已经尝试过:
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
检查文件夹pkgconfig的内容:
freetype2.pc GraphicsMagick.pc GraphicsMagick++.pc GraphicsMagickWand.pc libpng15.pc libpng.pc
我在这里缺少什么?
