#13 /src/ext4magic-0.3.2/src/recover.c:478: undefined reference to `makedev'

[Brian J. Murrell]

During building:

ext4magic-recover.o: In function `recover_file':

Sadly though, this project seems abandoned as even years old patches are not being applied. :-(

You need to add an include in file src/recover.c at line 24

#include <sys/sysmacros.h>
