Add this *above* the includes, just like in the > kernel. ah, got it ... for some reason, i thought it was that menuconfig setting that was responsible but now i see they're actually independent features. so, as i read it, using "#define DEBUG" causes this to kick in for a given source file: #ifdef DEBUG #define pr_debug(fmt, arg...) printf(fmt, ##arg) #else #define pr_debug(fmt, arg...) do {} while(0) #endif #define debug(fmt, arg...) pr_debug(fmt, ##arg) while that menuconfig setting for "low-level messages" defines operations for these (totally independent of DEBUG, right?) # define PUTC_LL(c) do {} while (0) # define PUTHEX_LL(v) do {} while (0) # define PUTS_LL(c) do {} while (0) thanks. rday -- ======================================================================== Robert P.
