In the compilation instruction, due to some wrong formatting it looks weird. Unfortunately I cannot edit the original ticket. Following is the correct one //Disable checksum sed -i 's/return ((int)(crc != png_ptr->crc));/return (0);/g' pngrutil.c autoreconf -f -i ./configure --disable-shared make clean all check Note that you may not need to disable the checksum check. We disabled it during fuzzing.
