ambiguous unresolved functions [message #808301]

First, please bear in mind that I'm a natural-born Java developer, so whatever is going on here is likely entirely my fault, and likely a trivial env problem.

I'm setting up a new C++ project using CDT (Version: Indigo Service Release 1 / Build id: 20110916-0149), since I'm so fond of the Eclipse Java IDE. I have Visual Studio 2003 installed as well, though I'm attempting to avoid using its IDE. My C++ project consists of half a dozen .cpp and .h files. Some of the .cpp files include libraries such as stdio.h, windows.h, and stdlib.h.

By right clicking the project and selecting Properties, I've (1) enabled the Indexer under C/C++ General --> Indexer, (2) set the INCLUDE and LIB env variables under C/C++ Build --> Environment to point to my Visual Studio include and lib dirs, and added several directories under C/C++ General --> Paths and Symbols / Includes / C++ Source File, such as Visual Studio's Vc7\lib, Vc7\PlatformSDK\Include, and VC7\include dirs. This clears most of my initial project errors (brings me down from 300+ errors to eight).

But as mentioned, I'm still seeing several error messages under Problems when I open one of the .cpp files. Some of the messages I'm seeing are:

'remove' is ambiguous 'Candidates are:int remove(const char *)'
'rename' is ambiguous 'Candidates are:int rename(const char *, const char *)'
Function 'fileno' could not be resolved

On the rename and remove errors, when I press F3 on either function to open the declaration, Eclipse pops up a dialog asking me to choose between the io.h and the stdio.h files located in the Vc7\include directory. As for the fileno, I've been told this is a standard C function, so I'm curious why it can't be resolved.

Can anyone shed some light on why I'm seeing these errors and what I can do to remedy them?

Why ?

Could you paste the call of the rename function ?

There are some "political" reasons for not using VS. Let's leave it at that. Smile

Here is the rename function call:

rename(fileName.c_str(), oldFile.c_str());

I was having the same problem, except mine was:

using namespace std;

[ std is ambiguous. candidates are ' ]

Some C++ project types have "built-in" settings for include paths, some do not. I copied the built-ins from a Hello World project and that seems to have fixed a multitude of sins. Unfortunately, the settings weren't written in the Export... file, and couldn't be copy/pasted, so I had to take a screen shot (attached here) and type them all in 1-by-1 (ughs....). Smile

Thanks,
Chris
