一个朋友给了一段代码让我调试,大意是移植了一些linux下的c程序,需要在windows里面由matlab调用。
粗粗看了一眼相关的东西,主要是用matlab里面的mex函数来调用c函数就可以,编译环境可以实现配置,也可以交互配置。结果一编译,错误就来了
错误是:

分析:看起来,应该首先解决'u_int8_t‘这个类型定义。找了找,windows里面没有,vc里面也没有。网上搜了一下,定义的方式应该是
“typedef unsigned char            u_int8_t, u_int8m_t;”
源代码的前面有句话,#include ,所以我就把这个定义放在了types.h里面了。
编译,通过!
但是报告:

意思是外部函数连接有问题,看了看那个外部函数Extract_Texture_Features在cvip_pgmtexture.c里面放着呢,于是,想到应该联合编译,
>> mex E:\Ctomexw32\cvip_pgmtexture.c E:\Ctomexw32\ml_texture.c
??? ml_texture requires a single input argument.

??? Error using ==> edit>handleError at 462
Can't edit the MEX-file 'D:\My Documents\MATLAB\cvip_pgmtexture.mexw32'.
 
这就没有什么问题啦。
