Error when using .include directive in Gnu Assembler!

[Cliff Tsai]

Hi:
    I'm trying .macro 
 
 
   I've try to use following codes in 
assembly.
    abc.h:
        
#define     a    0x1
        #define 
    b    0x2
        
#define     c    0x3
 
    test.s:
    
        #include 
"abc.h"
        .
        .
        .
         
        But when linking 
error occurs:
            
undefined reference to 'a'
            undefined 
reference to 'b'
            undefined 
reference to 'c'
            
 
        
Thanks!
