i'm tring to create a .dll file from this .c code (for Labview). http://www.mathworks.com/matlabcentral/fileexchange/26190-vchoosek

But i'm not able to compile it nor with VisualStudio nor with "mcc" because both compilers return this error:

VChooseK.obj : error LNK2019: unresolved external symbol mexErrMsgIdAndTxt referenced in function BadInputTypeError 
VChooseK.obj : error LNK2019: unresolved external symbol mxFree referenced in function ElemK_8Byte

VChooseK.obj : error LNK2019: unresolved external symbol mxIsChar referenced in function mexFunction 
VChooseK.obj : error LNK2019: unresolved external symbol mxIsNumeric referenced in function mexFunction

Someone could help me? I've already include the path of "mex.h" in VisualStudio

You must include the important libraries for linking. The libraries like libmex.lib;libmat.lib;libmx.lib and others if needed. If you are using the MATLAB 2018b, the include path must include "C:\Program Files\MATLAB\R2018b\extern\include" and Library Path "C:\Program Files\MATLAB\R2018b\extern\lib\win64\microsoft".

  • The error message is for linking issue. Check matlabroot for the Matlab installation folder. matlabroot will return 'C:\Program Files\MATLAB\R2018b'. You can find include folder inside "C:\Program Files\MATLAB\R2018b\extern" and Library files inside "C:\Program Files\MATLAB\R2018b\extern\lib\win64\microsoft". – Pramod Kumar Apr 26 '22 at 18:46
