conditional ifdef, how to do OR statement?

[Admin]

I can't figure out how to do an OR statement using ifdef.

My best guess:

Code: [Select]

     #ifdef MACRO1 || MACRO2
     
     controlled text
     
     #endif
but it doesn't work . . .
../file.h:156:18: warning: extra tokens at end of #ifdef directive

Anyone know?

Try

Code: [Select]

#if defined(TEST_1) || defined(TEST_2)
// do stuff
#endif

It works! Thanks!
