Error Lnk2019 Unresolved External Symbol Winmain@16 Referenced In Function ___tmaincrtstartup
up vote 0 down vote favorite 1 I'm trying to read a .mat-file in C++ with MSVS 2008 but when building a simple program I get the following error: 1>ex3.obj : error LNK2019: unresolved external symbol _matClose referenced in function _main 1>ex3.obj : error LNK2019: unresolved external symbol _matOpen referenced in function _main I've researched Google as well and it seems that the compiler can't link to error lnk2019 unresolved external symbol visual studio 2010 the libraries needed for using this functions (matOpen and matClose). I never used an external library before but I tried everything I found in Google to add the Matlab libraries. I did the following: TOOLS --> Options --> Projects and Solutions --> VC++ Directories --> Show directories for: include files --> then I added the path of the matlab include directory --> C:\Program Files\MATLAB\extern\include I did the same with the library files: C:\Program Files\MATLAB\extern\lib\win64\microsoft I also did that for the project: Right click on the project --> Properties --> Configuration Properties --> C/C++ --> General --> Additional Include Directories --> and added "C:\Program Files\MATLAB\extern\include\win64" Then I did the same at Linker --> General --> Additional Library Directories --> and added "C:\Program Files\MATLAB\extern\lib\win64\microsoft" So I really don't know where the problem is. Here is the source code I'm trying to build: #include

I am currently working on using Visual C++ and compile with Visual Studio 2010. I have followed several tutorials on building against library files to no avail; I always see the error: "error LNK2019: unresolved external symbol _matClose referenced in function _wmain" . I have set the path (C:\Program Files\MATLAB\R2010b\extern\lib\win64\microsoft) to the lib files in Configuration Properties > Linker > General > Additional Library Directories I have set the library file names (libmat.lib, libmx.lib) in Configuration Properties > Linker > Input > Additional Dependencies I have set the include file path (C:\Program Files\MATLAB\R2010b\extern\include) in Configuration Properties > C/C++ > General > Additional Include Directories I don't see any error about not being able to find the .lib file, but I see one if I alter one of the .lib files names to a file that does not exists. I am fairly certain the lib files are being found at compile time. The header files also seem to be set up correctly. I don't have any ideas left in this noggin so if ANYO

But I face the above problem while compiling second library and when I changed my application to windows, I see a different linking error now which is "msvcrt.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup" ..any idea how to resolve this ?
