我正在使用MATLAB R2012A和Visual Studio 2013。
我在simulation.m文件中有一个简单的函数。
function [ r ] = simulation( )
r = 42;
end
由于MATLAB 2012不支持VS2013,我使用these files在MATLAB中设置了我的VS版本。 然后我使用:
构建了相应的dll>> mcc -v -W lib:libsim -T link:lib simulation.m

我现在有以下文件:
libsim.dll
libsum.exp
libsim.c
libsim.exports
libsim.h
我已经安装了64bit MATLAB runtime for MATLAB R2012a。
我在VS中创建了一个新的C ++解决方案,并添加了libsim.lib
依赖项以及matlab lib / include目录。
这是我的主要cpp文件:
#include <cstdio>
#include <libsim.h>
int main(void)
{
double v = 42;
libsimInitialize();
printf("%d\n", v);
libsimTerminate();
return 0;
}

就在那里,Lib\matlab
和Include\matlab
路径都有matlab运行时库和标题的副本。
可是。它。没有。再用。编译。

注意编译器如何查找前缀为下划线的符号。如果使用DUMPBIN查看lib文件中的符号,您可以看到它们没有前缀(full DUMPBIN output):

为什么它不起作用,如何从C ++调用我的matlab函数?
答案 0 :(得分:1)
好的,结果是VS项目是32位,但是MATLAB生成的lib / dll是64位。通过将VS项目切换到x64,它已编译。
VS似乎默默地忽略了将32位可执行文件与64位库链接
