How can I redefine something without it screwing up?

I am trying to define the title ID to install via the Menu selection.

Aka Install With Trucha = Define IOS36
Install Without = Define IOS35

But I cannot use the #define more than once without it screwing with me.

I also cannot use:
INPUT_VERSION= 12;

or it will spew out an error.
error: lvalue required as left operand of assignment

Should I just remove the defines and replace them with int?

Thanks for any help!

static

#define XYZ (1)

#undef XYZ

#define XYZ (2)

#ifdef XYZ
#undef XYZ
#define XYZ whatever
#endif

Or heaven forbid, use a variable. That's what it's meant for, something that changes, AKA variable

so yes static int input_version;

And then assign input_version when you need to.

Hi Tantric. I noticed that you use static global variables in some of your libwiigui cpp files (thanks for the great library!). This uses internal linkage and thus helps prevent name clashes, but before encouraging other people to use static, I just wanted to mention that the C++ standard now recommends using namespaces to prevent name clashes. I personally feel namespaces are overlooked too often, and would like to encourage library authors to use them.
