Hello Everybody, Firstly I would like to apologize for one too many questions that I have already asked.I have a deadline coming up, hence ... I have a function in which I am using the hash_48 unit.A snippet of my code is : hashInputTmp.hash_lo32 = ip_32; // This is an IP address hashInputTmp.hash_hi16 = ip_32 >> 16; // This is just a filler and the values does not really matter hashInput = hashInputTmp; However I get a compilation error for the following 3 lines of code : hash_48(&hashInput, &hashOutput, 1, ctx_swap); hashIndex = hashOutput.hash_lo32 & 0xff; tableEntry = &(hashTableIP[hashIndex]); (I have followed the same model as in Chapter 8/9) for the hash. Here if I comment out any of the above 3 lines , the compilation error goes away. The error that I get is : (0): error : Function __mul_32 not found I dont see any multiplication here , so I really cant figure out what the problem is. Looking forward to some feedback.
