There is a funny workaround though. You can find > "static __inline__ int32_t SUFFIX (grc3_resample_)" definition in > grc3inc.inc and add "const" qualifier before "void *src". But I hate > the idea to work around gcc bugs. Or the problem may be caused by "const void *" type of the src parameter of grc3_convert. The grc3_resample routine doesn't have const. I did a modification to the hg version where "const" is removed. Maybe it fixes the warning.
Strange that I don't get this warning in my Linux system(s). Best regards, Hannu _______________________________________________ oss-devel mailing list oss-devel@mailman.opensound.com http://mailman.opensound.com/mailman/listinfo/oss-devel
