Hi there,

I have a problem which I'd be very grateful for some help with...

I'm trying to use the 'close' function used for file descriptors etc, but even when I have the line '#include <unistd.h>', I get the message:

'close' was not declared in this scope.

The Xcode project includes some code involving sockets. The list of included headers is as follows:

#include <unistd.h>

#include <sys/ioctl.h>

#include <sys/types/h>

#include <sys/uio.h>

#include <stdlib.h>

#include <sys/socket.h>

#include <netinet/in.h>

#include <arpa.inet.h>

The calls to 'socket', 'recv' etc compile fine - it's just the problem with 'close'.

My SDKROOT variable is set to /Developer/SDKs/MacOSX10.4u.sdk/

I tried linking to an editable copy of the 10.4u SDK I'd placed on my Desktop, and by adding lines to cause errors, it seems that when interpreting the line:

#include <unistd.h>

my Xcode project includes the file '$(SDKROOT)/usr/include/usr/unistd.h'

instead of the one where 'close' is defined which I need: $(SDKROOT)/usr/include/unistd.h' (which includes the one above anyway).

I don't have any special header search paths relating to the SDK - only paths to our own code.

A temporary measure is to substitute the line:

'#include "usr/include/unistd.h" '

since this removes the error, but this is probably the wrong way to go about it, since it just sweeps the problem under the carpet...

Could anybody suggest what I need to do to solve this?

Thanks,

Tom
