Compilation error during make after std ./configure values dictated in the blfs book.

1- most correct solution:
Change the line 425 column 13 value of the source file convert/source-ext2.c from  e_value_block to e_value_offs. In this case compilation runs off correctly and the final btrfs-convert function is available in the system.

2- otherwise add in the .configure step the option  -- disable-convert. In this case obviously the btrfs-convert function is absent .

struct ext2_ext_attr_entry is defined in /usr/include/ext2fs/ext2_ext_attr.h

My version of that does have

 __u32 e_value_block; /* disk block attribute is stored on (n/i) */

what version of e2fsprogs do you have?  It should be 1.43.9.

Also, using e_value_offs may satisfy the compiler, but does not do the right thing for the logic of the program.
