Question

see in one code i have written

void my_function()
{
INT32 i;    /* Variable for iteration */ 
/* If system is little-endian, store bytes in array as reverse order */
#ifdef LITTLE   
   {    
    // i m using i for operating one loop 
   }
#endif

 /* If the system is big-endian, store bytes in array as forward order */
#ifdef  BIG 
   {
   // using i for loop
   }
#endif
return;
 }

by compiling this code with -Wall flag it shows

 warning: unused variable ‘i’      

why?
how can i remove this?

Answer 1

hey i got the answer…

see BIG & LITTLE are preposser flag & they are given at compile time.
when i was compiling my project with make file i was giving this flag at compile time but while testing each individual file i was compiling like

gcc -Wall -c filename.c 

This was comming because i havent given any flag so compiler going to neglet that much portion of code & i was getting warning.

gcc -Wall -c -LITTLE filename.c 

works perfectly…
