Hello,
I am trying to compile a SharedMemory.cpp via mex and Visual Studio 2010 c++ compiler on a Win32 machine.
What I input :
mex -v -O -win32 -I'C:\Program Files\Boost\boost_1_51' SharedMemory.cpp
The output :
-> Default options filename found in C:\Users\Skyhr\AppData\Roaming\MathWorks\MATLAB\R2012b

I am not very familiar with C++. Can someone please explain what the error is and how to fix it? From seeing others use this without any problems - the code should be working because others have compiled it and are using it without any problems. The cpp file uses libraries from the Boost library.

It looks like you are missing the definition of the struct mxArray_tag. This used to be part of the matrix.h file up to R2010a, but has since been deleted. Since you are using R2012b my guess is that is the root problem. The fix may be to simply include it manually based on what was published in an older version. E.g., see this link to Yair Altman's Undocumented MATLAB site for examples:

Where is libboost_date_time-vc100-mt-1_51.lib located? Try putting in in the same directory as SharedMemory.cpp.

Oh my God... hahaha
http://sourceforge.net/projects/boost/files/boost-binaries/1.51.0/
has a list of libraries, where I found the missing one. It doesn't work when I put it in the boost folder, but works when I put it in the folder containing SharedMemory.cpp. I have no idea WHY boost didn't automatically give this to me when I installed it, but hey, at least it got the job done.
Thank you very much! :)
