Subject: Re: flashing large eMMC partitions with ext4


> amir@...ab:~$ gcc -o uninit_bg -lext2fs uninit_bg.c

For me, it gives error:

$ gcc -o uninit_bg -lext2fs uninit_bg.c
uninit_bg.c: In function ‘main’:
uninit_bg.c:105:2: error: invalid use of undefined type ‘struct opaque_ext2_group_desc’
uninit_bg.c:105:5: warning: assignment from incompatible pointer type

I have the latest source code from
but nowhere I can find the full declaration of
struct opaque_ext2_group_desc.

Am I missing something?
I didn't want to bother you for this, but I could not
solve the puzzle.
