error: ‘readdir_r’ is deprecated

Hello,
when I tried to cross-compile on lubuntu 16.04 into arm64 I got 'error: ‘readdir_r’ is deprecated'.

shell log is:
lubuntu@lubuntu:~/dexRepair$ ./make.sh make: Entering directory '/home/lubuntu/dexRepair/src' rm -f *.o rm -f dexRepair make: Leaving directory '/home/lubuntu/dexRepair/src' make: Entering directory '/home/lubuntu/dexRepair/src' cc -c -std=c11 -D_GNU_SOURCE -Wall -Wextra -Werror -c dexRepair.c -o dexRepair.o cc -c -std=c11 -D_GNU_SOURCE -Wall -Wextra -Werror -c log.c -o log.o cc -c -std=c11 -D_GNU_SOURCE -Wall -Wextra -Werror -c utils.c -o utils.o utils.c: In function ‘utils_readdir’: utils.c:45:9: error: ‘readdir_r’ is deprecated [-Werror=deprecated-declarations] if (readdir_r(dir, &de, &res) > 0) { ^~ In file included from utils.c:26:0: /usr/include/dirent.h:183:12: note: declared here extern int readdir_r (DIR *__restrict __dirp, ^~~~~~~~~ cc1: all warnings being treated as errors Makefile:36: recipe for target 'utils.o' failed make: *** [utils.o] Error 1 make: Leaving directory '/home/lubuntu/dexRepair/src' [-] gcc build failed

Can you please update utils.c so that it will be compatible with readdir command instead of readdir_r ?

Also, it will be REALLY HELPFUL if you could compile dexRepair and publish the bin for arm & arm64, since source compiling is HARD for me.

Req: dex SHA-1 signature repair, not just alder32 checksum

Dear @anestisb
as known, dexRepair can fix dex file alder32 checksum, but not its SHA-1 signature.
can you please add SHA-1 signature repair as well to dexRepair ?

IMHO, it would be advisable to separate it as a different switch then the already existing checksum repair, since SHA-1 repair should come before adler32 checksum and that SHA-1 calculation is considerable longer then alder32 checksum calculation.

I hope you can add such feature to the already great dexRepair :-)

P.S - as i'm a user in this repo(not dev), I can't label this issues at all - only you can @anestisb.
