我目前正在使用C中的CPLEX API在MATLAB中編寫MEX文件來解決線性編程問題。使用CPLEX API的MEX文件的編譯器錯誤
不幸的是，當我嘗試編譯時遇到了一個「架構x86_64找不到的符號」的問題，我不知道如何解決它。我在下面包含了一個（MATLAB）輸出的副本。我需要做什麼才能成功編譯？
還有很多鏈接器'無法創建緊湊的展開'與寄存器分配和保存相關的錯誤。很多我刪除了80％，使其更具可讀性。這些有關係嗎？他們是否值得關注？
可能有幫助的其他一些信息：
- 我可以編譯yprime.c等MEX文件不使用CPLEX API
- 我使用MATLAB 2011B在Mac OSX 10.7.2
- 我正在使用XCode 4.2中包含的GCC 4.2程序包。
- 我已經應用的XCode 4.2修補MATLAB

解決的問題：
以供將來參考，警告消息是在使用CPLEX時不是問題。實際的問題是通常捆綁在XCode 4.2中包含的CoreFoundation和IOKit框架中的缺失符號。通常可以通過使用-framework CoreFoundation和-framework IOKit標誌來包含它們，但是MATLAB中的mex命令不支持該功能。然而，幸運的是，您可以使用LDFLAGS ='\ $ LDFLAGS -framework CoreFoundation -framework IOKit'爲鏈接過程添加基於自定義的標誌...
