I took a minute and tried to put together a opensuse package for
ext4magic in my home directory for testing.

https://build.opensuse.org/package/show?package=ext4magic&project=home%3Agregfreemyer%3ATools-for-forensic-boot-cd

I haven't tried to patch the source, but at present it has some
compile errors that keep OBS from publishing it even from a home
directory.

====
I: Program returns random data in a function
E: ext4magic no-return-in-nonvoid-function hard_link_stack.c:87
E: ext4magic no-return-in-nonvoid-function imap_search.c:362
E: ext4magic no-return-in-nonvoid-function magic_block_scan.c:203, 1028, 249

I: A function uses a 'return;' statement, but has actually a value
   to return, like an integer ('return 42;') or similar.
W: ext4magic voidreturn ext4magic.c:888

I: Program is using implicit definitions of functions getting
   pointers or implemented by macros. These functions need to use their
   correct prototypes to allow correct argument passing on e.g. x86_64 .
     - Implicit memory/string functions need #include <string.h>.
     - Implicit *printf functions need #include <stdio.h>.
     - Implicit *printf functions need #include <stdio.h>.
     - Implicit *read* functions need #include <unistd.h>.
     - Implicit *recv* functions need #include <sys/socket.h>.
W: ext4magic implicit-pointer-decl journal.c:754

=====

I think just the E: errors are mandatory to fix for OBS to publish the
package, but I'm not sure about that.

Roberto, if you think you'll come out with a cleaner build in the next
couple weeks, I won't bother to patch up those errors.

Thanks
Greg
