如何在Objective C / XCode中使用CImg？

Question

I know that clang can compile C++ files as .mm , but CImg comes as just an individual .h file. Regardless if I change the extension to .mm or keep it as .h , it doesn't work.

First, it complains that it can't find cstdio.h . As a result, I changed all the cstd.. imports to their c counterpart as a

// Include standard C++ headers.
// This is the minimal set of required headers to make CImg-based codes compile.
#include <stdio.h> // (was #import <cstdio>)
#include <stdlib.h>
#include <stdarg.h>
#include <string.h>
#include <math.h>
#include <time.h>
#include <exception.h>

After bringing in the x11 library, I get past the import errors into syntax errors:

namespace cimg_library_suffixed {

Error: Unknown type name 'namespace'

Is this because I changed cstdio to stdio ? I'm confused..

The solution in answer form for future reference:

Compile the file the header is #include d from as Obj-C++ and the header will get treated as C++ code.
