James, try to compile http://www.mathworks.com/matlabcentral/fileexchange/21233
. Or add "
// undef needed for LCC compiler
#undef EXTERN_C
#include <process.h>".

I am using R2007a on a 32 bit Windows XP Sp2.

Hi Lorgio, I gave up compiling SerialIO within matlab. Correct me if I am wrong but the maltab internal lcc compiler won't compile serialIO.cpp correctly and hence a c++ compiler should be used. I set up my vc++ compiler (Visual C++ 2008) to compile the mex file via vc++ (see http://www.icaen.uiowa.edu/~dip/lecture/C++_with_Matlab.pdf). I am getting following errors (seems some of the syntax has c slang that the c++ compiler rejects):

1><path>\visual studio 2008\projects\mexserialio\mexserialio\serialio.cpp(332) : warning C4996: 'sprintf': This function or variable may be unsafe. Consider using sprintf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

Any ideas? Feedback highly appreciated. In the original code, sleep was written lower case. Changing e.g. 'sleep(5)' to 'Sleep(5)' removed 3 errors.... quite picky compiler....

Thanks a lot!

Largio.

Made the following changes to the source code and got a clean compile and it runs help ok.
Haven't tried any other functionality yet.

line 32 commented out #define Thread
added cast to lines 442,458,460

Do you think it will work with these changes
Thanks

Lorgio.

I am using R2009b on a 64 bit Windows 7 machine with Visual Studio 2008 as my compiler.

When I try to compile I get:

>> mex SerialIO.cpp
SerialIO.cpp
SerialIO.cpp(73) : error C3861: 'sleep': identifier not found
SerialIO.cpp(77) : error C3861: '_endthreadex': identifier not found

  C:\PROGRA~1\MATLAB\R2009B\BIN\MEX.PL: Error: Compile of 'SerialIO.cpp' failed.
 
??? Error using ==> mex at 221
Unable to complete successfully.
 
It probably is my system confihuration. I'm not a c++ programmer.
Any Suggestions.
Thanks
James
