Are there any functions or classes in c.c++ to traverse directoires?

Hello!

I'm trying to run one of the example programs of the wxWindows
tutorial using the Dev-C++ 4 IDE (under Windows 2000).

=46or this purpose I first installed and built the wxWindows library
according to the recommendations given on
http://www.wxwindows.org/devcpp.htm.

Compilation of the sample application (see attachment) happens without
problems, but linking fails due to following errors:

Hi.

I think I know why the empty resource file is created and I concider it a=
 bug.

In 'Project'->'Project Options'->'Version Info' you have checked AND=
 unchecked the 'include version...'
This makes the compiler complaint: [Resource Error] no resources

Thanks to Carlos (cgm1) for pointing out where to put default include
directories.  It works nice.  Now, along with Ioannis' dev-cpp fix file I am
moving right along.

One issue came up that someone else might encounter - all of a sudden I
started getting build errors complaining of an empty resource file.
Apparently Dev-cpp just writes this file for some reason, most likely in
response to something I did, but you can not compile until you simply delete
this resource file again.  Is that a bug or a feature?
