Commit 51003b89 [kwbimage.c: Fix compile warning when building on 64 bit systems] changed the printf format for "sizeof(uint32_t)" from "%d" to "%ld". This now generates the following warning on 32 bit build systems:
tools/kwbimage.c: In function ‘kwbimage_checksum32’: tools/kwbimage.c:135: warning: format ‘%ld’ expects type ‘long int’, but argument 4 has type ‘unsigned int’
The problem is that sizeof(uint32_t) has different types on 32 bit and 64 bit build systems. This patch now changes the format to "%d" again and casts sizeof() to uint32_t, fixing the problem on both build systems.
if (len % sizeof(uint32_t)) {
printf ("Error:%s[%d] - lenght is not in multiple of %ld\n",
__FUNCTION__, len, sizeof(uint32_t));
printf ("Error:%s[%d] - lenght is not in multiple of %d\n",
__FUNCTION__, len, (uint32_t)sizeof(uint32_t));
why not do it right ? use PRIu32 from inttypes.h like POSIX intended. might as well fix the typo in the message ("length") while you're here, and use the standardized __func__ ... -mike
