2008-04-28 17:02:45     Build error when enabling jffs2

Henrik Holm (UNITED STATES)

Message: 55171    I am trying to enable jffs2, but the build process fails.   It is easily reproducible (for me) -- I unpack a pristine 2008R1-RC8 uClinux tree, do 'make menuconfig' and modify

Linux Kernel Configuration

->File systems

  ->Miscellaneous filesystems

    ->Journalling Flash File System v2 (JFFS2) support

from <M> to <*>.  Then I do "make", and the build fails.  The last message I see is,

LINK    busybox_unstripped

bfin-uclinux-strip: busybox_unstripped: File format not recognized

make[3]: Leaving directory `/home/hholm/uClinux-dist-2008R1-RC8/user/busybox'

I looked through the ouput from the build and found this about 500 lines above:

My build host is Ubuntu 7.10 -- is this relevant?  Is there something extra I need to install on the build host?  (Note that a pristine 2008R1-RC8 builds without problems.

Thanks,

Henrik

Message: 55177    please review the documentation for setting up your development host:

http://docs.blackfin.uclinux.org/doku.php?id=installing_linux

you need the development package for zlib
