Hey, I'm trying to get up and running using Eclipse, but I cant even do the simplest program. Literally a program with an empty main() function and just #include <iostream> gives a mass of errors. The only similar issue I can find on the web is when the file is named the same as an STL file, which is not the case for me. Copy/paste of errors below. Any help much appreciated!

That doesn't work.

Do you resolve? I wish your reply!

What is the full command line for the compilation? It seems like it might be a #define (from the command line?) that's preventing a C header from being included by the C++ header.

I just debugged this error. Necro'ing because it's high in the Google results when searching for the error message.

The problem is that a standard header was included from within a namespace. Example:

test.cc
test.h

Just to clarify:

1. C++ namespaces are Good.

2. It's OK to use namespaces inside a .cpp source file.
It's also OK to use namespaces inside a .h header file.

3. But you should #include your headers OUTSIDE of the namespace.

Oh indeed. I took all that as a given. Sorry if I misled.
