Re: [Ltib] tar with gzip in busybox

[Marten Lootsma]

Hi Peter,

Thank you for pointing me to the right direction. I 
found the option, however not as a sub item of tar. I guess this is 
another configuration because I use a Freescale BSP with Busybox 1.15.

Best regards,

Marten Lootsma

FYI, my Busybox Archival Utilities configuration:

Dear list members,

I am upgrading a LTIB version given by Freescale (mx35 SDK1_5 to SDK1_7). This question might be misplaced on this list, but I have a problem with tar in Busybox (1.15). The tar option 'z' for gzip support is not recognized:

******************************************************************
address@hidden /mnt/appl/bin$ tar xzvf mb.tar.gz
tar: invalid option -- z
BusyBox v1.15.0 () multi-call binary

Usage: tar -[cxtvO] [-f TARFILE] [-C DIR] [FILE(s)]...

Create, extract, or list files from a tar file

Options:
    c    Create
    x    Extract
    t    List
Archive format selection:
File selection:
    f    Name of TARFILE or "-" for stdin
    O    Extract to stdout
    C    Change to directory DIR before operation
    v    Verbose

address@hidden /mnt/appl/bin$ tar xvf mb.tar.gz 
tar: invalid tar magic
******************************************************************

Note that gunzip is working. I searched in the busybox config, but I could a way to add gzip support to tar.

Does someone has a suggestion?

1) Configure LTIB by "./ltib -c"
2) In the menu under "Package List", select "Configure busybox at build time"
3) Save/exit this configuration.
4) LTIB will unpack busybox and present its configuration.
5) In busybox's config, select "Archival utilities"
6) Scroll down to "tar".
6) Select "Enable -z option" suboption of "tar"
7) Save/exit busybox configuration

At this point busybox will be rebuilt/redeployed, and when you load hte new image, you should have a working "-z" option on tar to invoke gzip/gunzip....

Thanks,
Marten
