ABOUT:
|
||||
------
|
||||
|
||||
This is a straight rip from the e2fsprogs pkg.
|
||||
|
||||
These files are used to support other misc progs ripped out of e2fsprogs
|
||||
and included in busybox.
|
||||
|
||||
-------
|
||||
UPDATE:
|
||||
-------
|
||||
|
||||
Simply copy the 'e2p' dir from e2fsprogs/lib/ and then delete the extra
|
||||
files we don't need (Makefile.in, e2p.pc.in, etc...). Update the e2p.h
|
||||
file to look for "../ext2_fs.h" instead of <ext2fs/ext2_fs.h>. Finally,
|
||||
remove the _LARGEFILE* define's from the few source files that use it
|
||||
since we'll be appending it ourselves to CFLAGS when we compile.
|
||||

STAMP:
