我目前正在MATLAB中编写MEX文件，该文件使用C语言中的CPLEX API来解决线性编程问题。
不幸的是，当我尝试编译并且我不知道如何解决它时，我遇到了“找不到架构x86_64的符号”问题。我在下面提供了（MATLAB）输出的副本。如何成功编译需要做什么？
链接器的批次无法创建与寄存器分配相关并保存的紧凑展开错误。这么多，我删除了80％，使其更具可读性。这些可以相关吗？他们是否值得关注？
其他一些可能有用的信息：
这是（MATLAB）输出：

问题已解决：
为了将来参考，使用CPLEX时警告消息不是问题。实际问题是缺少的符号，它们通常捆绑在CoreFoundation和IOKit框架中，这些框架包含在XCode 4.2中。通常可以使用-framework CoreFoundation和-framework IOKit标志来包含它们，但MATLAB中的mex命令不支持此功能。幸运的是，您可以使用LDFLAGS ='\ $ LDFLAGS -framework CoreFoundation -framework IOKit'为链接过程添加基于自定义的标志...
