Usually you use <iostream>

But you should make sure the Indexer is being given the compiler builtin paths.

Maybe the OP does not have a C/C++ toolkit in the machine.

On OS X, there are the compatibility issues between GCC and LLVM.

thank you for your assistance.

trouble is I wouldn't know how to check or change that. So how would you go about that?

You can check for the C toolkit:
Open OS X Terminal
Type: gcc --version
(There are two dashes before 'version').

The response should be like:
gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/c++/4.2.1
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Please open your Eclipse, open Help -> Help Contents -> C/C++ Development User Guide, and read at least the 'Before you begin' part.

Hi there, thanks for your help.

I tried what you suggested and this was the result:

USERs-MacBook:~ USER$ gcc --version
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
USERs-MacBook:~ USER$

I take it that means gcc is not even installed?

Sorry for the delay, I was out of country.

It seems that you do not have the C/C++ toolkit at all.
Google for 'OS X GCC install'.

My MacBook (OS X 10.11.6, El Capitan) responds:

MacBook-Pro:~ tauno$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/c++/4.2.1
