如何使用 CMake 和 Visual Studio 2010(64 位)构建 MATLAB R2011a(64 位)mex 文件? [英] How to use CMake and Visual Studio 2010 (64 bit) to build a MATLAB R2011a (64 bit) mex file?

问题描述

我想编写一个 CMakeLists.txt 以便 CMake 编写一个 Visual Studio 2010(64 位)解决方案文件，以便从 C++ 代码中为 MATLAB R2011a(64 位)构建一个 mex 函数 example.cxx.

I would like to write a CMakeLists.txt such that CMake writes a Visual Studio 2010 (64 bit) solution file to build a mex function for MATLAB R2011a (64 bit) from C++ code example.cxx.

1. 我不想使用 MATLAB 的编译器包装器 mex，而是设置 Visual Studio 解决方案文件，以便 Visual C++ 链接相关的 MATLAB 库.
2. example.cxx 除了 mex 文件所需的 MATLAB 库外，没有任何依赖项.
3. CMake 2.8.7 已正确设置，因此它使用 Visual Studio 2010 的 64 位生成器.

1. I do not want to use MATLAB's compiler wrapper mex but set up the Visual Studio solution file such that Visual C++ links the relevant MATLAB libraries.
2. example.cxx has no dependencies except for the MATLAB libraries that are necessary for mex files.
3. CMake 2.8.7 is set up correctly such that it uses the 64 bit generator for Visual Studio 2010.

我现在所做的事情的本质是

The essence of what I am doing right now is

find_package(Matlab)
add_library(example STATIC example.cxx)
target_link_libraries(example ${MATLAB_LIBRARIES})

编译器和链接器都不会发出任何错误.我将输出 example.lib 以 example.mexw64 名称安装在 MATLAB 路径中的目录中.当我从 MATLAB 调用 example 时，我收到错误消息

Neither the compiler nor the linker issues any errors. I install the output example.lib under the name example.mexw64 in a directory in MATLAB's path. When I call example from MATLAB, I get the error message

??? Invalid MEX-file
'C:...example.mexw64':
C:...example.mexw64 is not a valid Win32 application.

欢迎提出任何建议！

推荐答案

我遇到了同样的问题，这个链接 非常有帮助(也可以作为一个很好的例子，说明如何在 MATLAB MEX 文件中使用 ITK 顺便说一句).我认为对于您的情况，您需要将链接标志 "/export:mexFunction" 添加到您的 CMakeLists.txt 文件中.下面的例子:

I had the same problem and this link was very helpful (also serves as a nice example of how to use ITK in a MATLAB MEX file btw). I think for your case, you need to add the link flag "/export:mexFunction" to your CMakeLists.txt file. Example below:

PROJECT(example)
FIND_PACKAGE(Matlab REQUIRED)

INCLUDE_DIRECTORIES(${MATLAB_INCLUDE_DIR})

ADD_LIBRARY(example MODULE example.cpp)
ADD_DEFINITIONS(-DMATLAB_MEX_FILE)

# Needed for entry point.
SET_TARGET_PROPERTIES(example
PROPERTIES
LINK_FLAGS "/export:mexFunction"
)

# Change the dll extension to a mex extension.
set_target_properties(example PROPERTIES SUFFIX ".mexw64")

TARGET_LINK_LIBRARIES(example ${MATLAB_LIBRARIES})

请注意，FIND_PACKAGE(Matlab) 似乎并没有那么好用，所以这对某些人来说可能是个问题.我不得不通过将 MATLAB 路径硬编码到 CMakeLists.txt(本示例中未显示)来解决这个问题.

Note that the FIND_PACKAGE(Matlab) doesn't seem to work all that well, so that may be a problem for some people. I had to get around it by hard-coding the MATLAB paths into CMakeLists.txt (not shown in this example).
