我发布了一个不正确的mkmf.log，它只与gecoder相关联，而不是gecoder与gecode。这是mkmf.log 的正确版本。 http://pastebin.com/3yNpkvzw
这是我的mkmf.log的链接。 http://pastebin.com/8Yv7Cqd6＆lt; - 错误的一个！
（我使用的是Ruby 1.9.3。）我使用的下载说明：http://gecoder.rubyforge.org/installation.html。
我按照此处的说明使用gecode安装 Gecoder ，它给了我下面的错误日志：
1 ROR: Error installing gecoder-with-gecode:
2 ERROR: Failed to build gem native extension.

有人有什么想法吗？另外，我已经安装了所有依赖项
