I'm trying to build md5deep (http://md5deep.sourceforge.net/) for android, but with the default build setup, the assertion that sizeof(off_t) == 8 fails, indicating (AFAIK) that LFS isn't enabled. I've tried enabling by adding -D_FILE_OFFSET_BITS=64 to the gcc and g++ flags, but it still doesn't do the trick. Adding lines to print the values of _FILE_OFFSET_BITS and sizeof(off_t) shows that the former is indeed 64, but the latter is 4 instead of 8.
Any ideas why?
