I wrote a code for a one digit seven segment display(that took me a while) and when I try to upload to board it says "error compiling. Its driving me mad because there aren't any mistakes in the actual code and I have been trying to get a seven segment display to work for a while. What should I do? Please someone help me!
Thanks
P.S. this is the code:

Code: [Select]
// WCharacter.h prototypes
inline boolean isAlphaNumeric(int c) __attribute__((always_inline));


c is defined as a macro before arduino.h is included, use more... better names

I know this sounds weird, but put another declaration before the defines. I used this and it compiled:
Code: [Select]
int test;
#define a 13
#define b 12
#define c 11
#define d 10
#define e 9
// and on...


edit: An #include before the defines compiles ok also.
Watch for me on National Geographic Wild "When Sharks Attack: Gulf Coast Killers". Airs on June 22nd.

This is a result of the IDE injecting '#include "Arduino.h" before what it thinks is the first line of ( actual ) code. Some pre-processors are overlooked, #includes are an exception as it uses these to collect library files.
