我想使用Matlab 2012a使用OSX 10.9来获取文件。我用于mex文件的命令如下：
mex -v -L/usr/include/ -I/usr/include/ -I/usr/local/Cellar/hdf5/1.8.12/include/ -larmadillo -lgfortran armaMex_demo.cpp
文件armaMex_demp.cpp取决于位于/usr/include/armadillo的库armadillo。以下是我理解用于编译文件的命令：
-v表示详细-L/usr/include/告诉链接器在/usr/include/ -I/usr/include/告诉编译器在/usr/include/ -I/usr/local/Cellar/hdf5/1.8.12/include/与上述相同-larmadillo告诉班轮使用名为armadillo 不幸的是我无法编译该文件。这是我得到的输出

使用mex时出错（第206行） 无法成功完成。
run_demo出错（第3行） mex -v -L / usr / include / -I / usr / include / -I / usr / local / Cellar / hdf5 / 1.8.12 / include / -larmadillo -lgfortran armaMex_demo.cpp
有人可以解释我收到错误的原因吗？
修改1：
以下
mex -v -I/usr/include/ -I/usr/local/Cellar/hdf5/1.8.12/include/ armaMex_demo.cpp
的工作。有人可以解释为什么第一次失败但第二次没有？我只是通过反复试验才发现它。
