Hello! Help me please.I want to use Ogre3D in mex (for s-function). http://www.ogre3d.org/ But my .cpp file contains OGRE's include files which Matlab doesn't see. In Visual Studio it can be adjusted in properties of solution. http://s001.radikal.ru/i196/1104/e6/e04d2a5746f8.jpg Is it possible to make so in Matlab? I will be grateful for any answer.Thank you.

When you use the mex function, you should be able to use the -I flag to specify the include directories.

Is that what you are looking for?

Hi Natalia,

You need to put both the include path and the source files. So, for instance...

mex -IC:\OgreSDK\samples\include mymexfile.c

getenv() requires the name of an environment variable as its input, such as

getenv('OGRE_HOME')

to verify that OGRE_HOME is set.

I should do this operation for each folder? Or it is enough to add a folder which includes all the others?

In Visual Studio it looks:

Code
+ Configuration Properties 
       General 
           * Output Directory: $(OGRE_HOME)\bin\$(ConfigurationName) 
           * Intermediate Directory: $(OGRE_HOME)\obj\$(ConfigurationName) 
       Debugging 
           * Command: $(OGRE_HOME)\bin\$(ConfigurationName)\$(TargetFileName) 
           * Working Directory: $(OGRE_HOME)\bin\$(ConfigurationName) 
       C++ 
           General 
               * Additional Include Directories: ..\include;$(OGRE_HOME)\include;$(OGRE_HOME)\samples\include 
           Linker 
               General 
                   * Additional Library Directories: "$(OGRE_HOME)\lib" 
               Input 
                   * Additional Dependencies: OgreMain_d.lib OIS_d.lib

Yes, you will need to add each include path and the library directories. Use the -l and -L flags to add library paths (-l) and actual library files (-L).

Again, the documentation has a table of all supported compiler switches:

mex -IC:\OgreSDK\samples\include ExampleApplication.h
    C:\PROGRA~1\MATLAB\R2010B\BIN\MEX.PL: Error: 'ExampleApplication.h' not found. 
??? Error using ==> mex at 208
Unable to complete successfully.

I do not understand why there is an error...

And if I have 1000 include files.... I should specify all of them? By the way, simstruc.h I shouldn't specify a file, is it mean there are default folders in matlab?
