I have already install that version of bitbake.

Here is some error message I got:

bermuda@BERMUDA-MMN:~/OE$ bitbake disko-image

I goole ot but sill no answer at all..

Can you try bitbake -DDD disko-image? Maybe it'll give you a hint.
It doesn't even parse any receipts, so there has to be something
wrong with bitbake.

Here is what I saw when I type bitbake -DDD disko-image

bermuda@BERMUDA-MMN:~/omap3530$

also I m curious about why I type bitbake --version

I saw

bermuda@BERMUDA-MMN:~/omap3530$ bitbake --version
/usr/lib/pymodules/python2.6/bb/COW.py:29: DeprecationWarning: the sets module is deprecated
import types, sets
BitBake Build Tool Core version 1.8.12, bitbake version 1.8.8

but I'm very sure that I have install bitbake 1.8.18

by typing

./setup install

in the folder of bitbake 1.8.18 is ther any wrong here?

Did you set your PATH environment variable correctly?
You can set it like this:

export PATH=<path-to-bitbake-1.8.18-binary>:$PATH

Then you can try

which bitbake

to check whether it's called from the correct location.

after fix the problem of bitbake...

I still get the error message...

Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
Following is the list of potential problems / advisories:

Using dash as /bin/sh causes various subtle build problems, please use bash instead.


I have install all packages which may be needed...

but still some errors.@@

It looks like OpenEmbedded doesn't like the dash shell.
If you set the link /bin/sh to /bin/bash this error should be fixed.
