I've tried again now with a fresh copy of the latest nightly CB and the ogre mingw sdk.
Extracted all archives on D:\, respectively.
Started CB, created a new C++ console project on D:\ called test.
Removed main.cpp from the project.
Added the TinyOgre files to project, recursively.
Right-clicked on the project test -> Build options -> Selected test (instead of Debug) on the left panel -> Search directories -> Compiler -> Clicked the Add button -> I've put in D:\OgreSDK_mingw_v1-7-2\include\OGRE -> OK -> OK
At this point I've tried the "Find Declaration of", CC and "Open #include file" features, all of which do not work. Their respective errors are: "Not found", "The Parser is still parsing files" and "Not found".
I should note that the same occurs on the original main.cpp:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}
