#ifdef does not work
PostPosted: Tue Oct 11, 2011 6:07 am     Reply with quote
Hi,
I am struggling with a basic statement:
Code:

//#define USE_MID_VARS 1
int test()
{
   #ifdef USE_MID_VARS
      return 1;
   #elif
      return 2;
   #endif
}

Throws "Expression must evaluate to a constant" error.
What is wrong with that?

Cheers, M.

#ifdef is working just fine....

Use #else rather than #elif. #elif expects a condition, such as #elif defined BLAH. You need a plain #else.

God, of course you are right.
I overlooked it.

Thanks
