From: David Francis <[email protected]> In fixed31_32.h, in dc_fixpt_shl,'/' was used for division of one long long int by another long long int. As there is no inbuilt long long int division function in c, gcc inserted its own. However, gcc does not link the library that contains this function. To avoid this, use bitwise operators instead of /
