Question

我一直在尝试按照此链接中的教程：http://thebrainiac1.blogspot.com.es/2012/07/v-behaviorurldefaultvmlo.html

这是一个非常好的教程，但是当我到达第6步并运行compilemex时，编译失败了。我已经精确地遵循了教程，但可能是我使用不同的架构。我正在使用MacOSx Mavericks版本10.9.2。

如果有人在同一台机器上遇到同样的问题并设法解决它，请分享您的想法，因为我需要让它工作。非常感谢！

编译器输出：

compile failed

当我删除try catch int thecompilemex.m时，Matlab输出了这种类型的错误：使用mex时出错

我意识到这个问题很久以前就被问过了，但只是因为你从来没有找到答案而且它一直让你过夜：

这个错误的产生是因为一个变量（在这种情况下，int变量“verbosity”）被多次声明，特别是在'global.c'和'svm_hideo.c'中 - 从任一个删除'int verbosity'其中一个文件和你的mex源代码将顺利编译！
