Ok, thanks.
But no joy.
On a freshly-built copy of:
http://www.busybox.net/downloads/snapshots/busybox-unstable-20030806.tar.bz2
I get this:
-- begin --
BusyBox v1.00-pre2 (2003.08.06-23:12+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.
~ # mkdir /tmp/hello && cd /tmp/hello && wget http://http.us.debian.org/debian/pool/main/h/hello/hello_2.1.1-1_i386.deb
hello_2.1.1-1_i386.d 100% |*****************************| 47900 00:00 ETA
/tmp/hello # dpkg -i hello_2.1.1-1_i386.deb
Unpacking hello (from hello_2.1.1-1_i386.deb) ...
dpkg: crc error
-- end --
There's only one place this error comes from: unzip.c line 1030
-- begin --
-> find /mnt/d4/coll.software.living-room-os/work/pkg/busybox/ -type f |xargs grep "crc error" | egrep -vi 'binary file'
/mnt/d4/coll.software.living-room-os/work/pkg/busybox/busybox/archival/unzip.c: bb_error_msg("Invalid compressed data--crc error");
/mnt/d4/coll.software.living-room-os/work/pkg/busybox/busybox/archival/libunarchive/unzip.c: bb_error_msg_and_die("crc error");
/mnt/d4/coll.software.living-room-os/work/pkg/busybox/busybox/libbb/interface.c: unsigned long rx_crc_errors; /* recved pkt with crc error */
-- end --
This is all after I've put a simple /var/lib/dpkg/status in place, of
course; otherwise dpkg exits with a "dpkg: /var/lib/dpkg/status: No
such file or directory" error.
The control.tar.gz and data.tar.gz files inside can be untarred correctly:
-- begin --
/tmp/hello # ls -l

/tmp/hello # ar -x hello_2.1.1-1_i386.deb
