如何使用CMake和Visual Studio 2010中（64位），以建立一个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

我想编写一个的CMakeLists.txt 这样的CMake写一个Visual Studio 2010（64位）解决方案文件建立一个MEX功能MATLAB R2011a（64位）从C + + code 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 MEX ，但设置了Visual Studio解决方案文件，这样的Visual C ++链接相关的MATLAB库。
2. example.cxx 有除了MATLAB库所必需的MEX文件没有依赖关系。
3. 的CMake 2.8.7设置正确，这样它采用了64位发生器的Visual Studio 2010。

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.

什么，我现在做的实质是

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})

无论是编译器和链接器发出任何错误。我安装的输出 example.lib 下在MATLAB的路径的目录名称 example.mexw64 。当我打电话例如从MATLAB，我得到错误信息

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.

任何建议，欢迎！

Any suggestions are welcome!

推荐答案

我有rel="nofollow">这个链接同样的问题，是非常有益的（也可作为如何使用一个很好的例子 ITK 在MATLAB MEX文件顺便说一句）。我觉得对于你的情况，你需要添加链接标记/输出：mexFunction您的CMakeLists.txt 文件。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})

注意 FIND_PACKAGE（Matlab的）似乎并没有工作那么好，所以这可能是一些人的问题。我必须得到解决它通过硬编码在MATLAB路径进入的C​​MakeLists.txt（在本例中未示出）。

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).
