我正在尝试在 Windows 8、Ruby 2.0 上安装 Rmagick gem - 所有这些都具有 64 位风格。我使用 RubyInstaller 安装了 Ruby 2.0 - 版本 2.0.0p247,在顶部安装了 DevKit-mingw64-64-4.7.2-20130224。然后我安装了 ImageMagic - ImageMagick-6.8.6-4-Q16-x64-dll 版本,确切地说,当然还有开发者头文件。所有都直接在 C: 驱动器的各个子文件夹中,名称中没有空格。然后我尝试构建一个宝石。
gem install rmagick --platform=ruby -- --with-opt-lib=c:/ImageMagi
ck-6.8.6-Q16/lib --with-opt-include=c:/ImageMagick-6.8.6-Q16/include
输出是

但是我认为问题不在 stdint.h 文件中。然后我检查文件的内容
c:\Ruby200-x64\lib\ruby\gems\2.0.0\gems\rmagick-2.13.2\ext\RMagick\
哪个是

这看起来像是 X11.lib 文件的问题。当然,它位于 ImageMagick lib 文件夹中,日期为 2009 年,我不知道下一步该做什么或对此有何看法。由于我正在处理一个大文件 - 6000x6000 像素,我希望尽可能使用 64 位版本。
