VS2010 source location problem.

[lucky6969b]

Firstly, I created a global environment variable OGRE_HOME=E:\ogre_source\OGRE
I unzipped a zip file into E:\ogre_source\OGRE\pathfinding

E:\
   ogre_source
                OGRE
                      pathfinding
                                  bin
                                  src 
                                  samples
                                             src << here

Then, I have a path for the source specified in the "source folder" of the project in the project properties section,
$(OGRE_HOME)\pathfinding\samples

Inside this folder I have src folder in which contains a .cpp file
The file is hard-coded with path src\OgrerecastApplication.cpp

But the VS2010 compiler still cannot find this file. I wonder what other settings are involved?
Thanks

I don't understand. Where is this setting? Did you mean the "Source Directories" setting under the "VC++ Directories" section in the project properties? If so, did you read the description of that setting?

Hard coded where? What do you mean with "VS2010 compiler still cannot find this file"?

If you add the file to the project that should be good enough. If you try to find headers based on $(OGRE_HOME) you have to set the environment variable before starting VS. Either the process that starts VS has to define it or it has to be defined in the global environment (sometimes it requires log off/log on)

Thanks S_M_A, All your assumptions are correct. I meant source directories, yes, the compiler cannot find the cpp file
There is a question mark on the right hand side of the tree control for that particular .cpp file

I have done this.
setx OGRE_HOME e:\ogre_source\ogre



If you need further info on the Chinese interpretation, let me know

Like I said, read the description of the "source directories" setting. It's only related to intellisense.
The files that are included in your project are referenced by a path that is relative to the project file. If they cannot be found either fix the directory structure or remove the file from the project and add the correct one.
