That's because printf() is from the host's libraries. lib_generic/md5.c is not a host-provided library, so you don't want to use a host-provided header. > > > 2) Use relative file names (as suggested by Kumar) or similar methods > > > to make sure we pick up the md5.h header file from a local > > > directory instead from /usr/include. > > > 3) Rename md5.h to make sure we use a pick up our own file instead of > > > some unrelated file which happens to have the same name. > > > > 2) seems to be more robust, though -- 3) works until someone installs a > > 2 is not robust.
