include files

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?

May be I do something not correctly... But at me the following message

mex -l $(OGRE_HOME)\samples\include

C:\PROGRA~1\MATLAB\R2010B\BIN\MEX.PL: Error: '$(OGRE_HOME)\samples\include' not found.

??? Error using ==> mex at 208

Unable to complete successfully.

Hmm... can you try it without using the $OGRE_HOME? I wonder if that is your problem.

Note that you can access environment variables in MATLAB using the getenv function. For instance, getenv('path')

[Natalia]

getenv ('C:\OgreSDK\samples\include')

ans =

''

mex -lC:\OgreSDK\samples\include

Usage:

MEX [option1 ... optionN] sourcefile1 [... sourcefileN]

[objectfile1 ... objectfileN] [libraryfile1 ... libraryfileN]

Use the -help option for more information, or consult the MATLAB API Guide.

C:\PROGRA~1\MATLAB\R2010B\BIN\MEX.PL: Error: No file names given.

Hi Natalia,

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

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

[Walter Roberson]

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

[Jarrod Rivituso]

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

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?

[Kaustubha Govind]

You don't have to specify names of header files - the -I option is added for the _directory_ containing the header files. You need something like:

mex -IC:\OgreSDK\samples\include -IC:\OgreSDK\include -I"..\include" -LC:\OgreSDK\lib mymexfile.c -l OgreMain_d.lib -l OIS_d.lib

Yes, simstruc.h is in a MATLAB directory that is automatically included by MEX

[Natalia]

Thank you! Your answers as always the most exact and clear for me :)

[Kaustubha Govind]

Glad to be of help. :)
