MATLAB: Mex – Compiler doesn’t include *.lib but they are there!

include librariesmex compiler

Hi,
I am using Matlab 2013a 64 Bit with the supported compiler from the Microsoft SDK 7.1, so far so good. I want to include some "*.lib" into my mex file that are needed, first idea was to include the whole directory with -L for the libs and -I for the headers needed. This worked well with some other mex files but with this file it fails. So I tried to include the libs directly using -l and this error message comes to the command window:
Warning: MEX could not find the library "D:\Sapera\Lib\Win64\SapClassBasic" specified with -l option.
         MEX looked for a file with one of the names: 
               D:\Sapera\Lib\Win64\SapClassBasic.lib 
               libD:\Sapera\Lib\Win64\SapClassBasic.lib 
         MEX looked for the library in the following directories: 
               C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\LIB\amd64 
               C:\Program Files\Microsoft SDKs\Windows\v7.1\LIB\X64 
               C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\ATLMFC\LIB\AMD64 
               C:\Program Files\MATLAB\R2013a\extern\lib\win64 
               C:\Program Files\MATLAB\R2013a\extern\lib\win64\microsoft 
               D:\Sapera\Lib\Win64\ 
               D:\Sapera\Lib\Win64\VS2010 
               C:\WinDDK\7600.16385.1\lib\Mfc 
               C:\WinDDK\7600.16385.1\lib\win7\amd64
The lib is there but the compiler doesn't find it and i so far don't know how to fix it, do you have an idea?

Hi,
it seems like you specified the full name to the lib file. That is not needed. with -L flag you specifiy the folders to look in and with -l you specify the filename only, e.g.
mex yourcode.c -LD:\Sapera\Lib\Win64\ -lSapClassBasic
