RE: [Dev-C++] Demystifying namespace

You shouldn't use #defines. #defines are cross-everything, they don't care
about scope, namespaces, functions, whatever. It's just a simple global
search&replace operation performed by the preprocessor. If you want your
namespace code to work, change it to something like:

namespace foo{
    const std::string file = __func__;
    const size_t      line = __LINE__;
} 

Note that I didn't test this though, but it should work (and didn't you mean
__FILE__ instead of __func__ there?)

Regards,


Paul

Subject: [Dev-C++] Demystifying namespace

I have a little bit of a problem with 'namespace'. Here is my problem:
namespace foo{
     #define file __func__
     #define line __LINE__
     enum error_t {one, two, three};
}
namespace foo{
    class loo{
       public:
          loo(){
             std::string f = foo::file;
             size_t l = foo::line;
             std::cout << "file: " << f << " line: " << l << std::endl;
             std::cout << foo::one << foo::two << foo::three << std::endl;
          }
    };
}
These std::cout's give me a parse error, what am I doing wrong?
