Let C18 throw a compiler error

Is there a way to let the C18 compiler throw an own, customized error message during compiling?

For example, consider a situation with two user-defined settings:

#define SETTING_A 0x80
#define SETTING_B 0x3f

Assume these settings can't be both 0x00. Is there a way to let the compiler throw an error (or at least a warning) when the user sets both settings to 0x00?

Solution

  • Consider using #if and #error:

    #if (SETTING_A == 0) && (SETTING_B == 0)
#error SETTING_A and SETTING_B can't both be 0!
#endif
