Question

我最近将一些我的Matlab代码转换为C并且它可以工作。但是，我想对这些mex文件进行一些更改并重新编译。

到目前为止，我只使用过简单的mex项目：通常包含两个这样的文件：

  Matlab_mex_Testing.m <--- I call mex function from here.
  mexcallingmatlab.c

然后我可以使用：

进行编译

  mex -g -ldl CFLAGS="\$CFLAGS -std=c99" -largeArrayDims mexcallingmatlab.c

但是，转换后的项目有多个* .c，* .o文件，当我尝试只编译.... _ mex.c时，我收到以下错误：

  ConstructSystemMatrix_2Translate_mex.c:24:1: warning: excess elements in struct initializer [enabled by default]
   emlrtContext emlrtContextGlobal = { true, false, EMLRT_VERSION_INFO, NULL, "ConstructSystemMatrix_2Translate", NULL, false, {2045744189U,2170104910U,2743257031U,4284093946U}, 0, false, 1, false };

  ans =

我可以看到正确包含各种头文件，例如“ConstructSystemMatrix_2Translate_initialize.h”等。

我还看到*.mki file有以下内容：

  # Make settings for ConstructSystemMatrix_2Translate

  OMPFLAGS=
  OMPLINKFLAGS=

我应该make some makefile out of this吗？如果是，有人可以指导我吗？

我正在运行Matlab R2014b（64位）
