Thread: Macros can suck my... something hairy

You can't win. I hardly ever use the beggars but when I do everything goes t*ts up.

Basically I've got a set of headers I want to use across several DLL's (so several projects) so I've got this directory structure:

Code:

ROOT ------ NothDebug
                |
                - NothKernel
                |
                - SharedLib
                |
                - Runtime

So ignore all of them except SharedLib. Basically it includes several headers and to save me typing "..\SharedLib\Singleton.h" (for example) I'm trying to get a macro like this to work:

Code:

#define SHARED(h) "...\SharedLib\" ## h

Of course I get "newline in constant" so I replace it with "...\\SharedLib\\" which doesn't work because now it can't find the header "..\\SharedLib\\Singleton.h".

I use it like this BTW:

Code:

#include SHARED(Singleton.h)

After trying to put #include in the macro which didn't work.
Help! Save my fingers!

I haven't got 3 dots in my editor. Must've been a typo as I copied it across. That'll teach me to use copy and paste next time

I'm pretty sure macros aint dynamic enough to do what you want...

Yeah I've given up on it. Stoopid macros.

Code:

#define SHARED(h) "...\SharedLib\" ## h

Correct me if I'm wrong, but shouldn't this be this:?

Code:

#define SHARED(h) "...\SharedLib\" #h

## is used to combine two symbols into one.
# is used to convert a value into a string.
