compiler-errors - 在这种情况下，如何修复体系结构x86_64的 undefined symbol ？

我正在尝试在Mac OS X 10.8.3计算机上编译cgminer。我使用自制软件安装了libcurl。花了一段时间才能使./configure正常工作，但我终于做到了(请参阅此问题How do I specify LDFLAGS and CPPFLAGS for ./configure?)。

现在，当我尝试对该程序进行make时，出现了似乎与Undefined symbols for architecture x86_64相关的错误curl。这是从头到尾的完整make消息:

从我阅读的所有内容来看，这是某种类型的链接器错误，而不是编译错误。这显示在./configure脚本的末尾:

我不知道如何解决链接器错误。我需要更改我的./configure吗？任何建议，不胜感激。

这似乎可行:
