How to rebuilt the package after modified the source code in open embedded bitbake ...

[surendra dhobale]

Hi,
 I am working with the open embedded environment. 

I have added one u-boot package in that. First time by default the compilation
done successfully using the bitbake. But Now i made some changes in the source
code , which is created in the Temp work directory.

Now i have to built the same package with neglecting the fetch() stage. 
and rebuilt it means need to compilation.

Is any commands for that...
Can please anyone explain me in deatails about that. I am newbie in the open
embedded.

Hi,
please note this will delete local changes (in thework directory) to
the sourcecode!

If you only want to compile again you can use

bitbake -c compile -f u-boot
and then "bitbake u-boot" to build the other tasks.

oops, I read his message to fast and didn't notice the "i made some
changes in the source code , which is created in the Temp work
directory".

For this kind of work, I prefer to do :
bitbake u-boot -c configure
copy the source from workdir to a directory outside OE
then change to this dir and
git init
git add .
git commit -m init
then you can hack it outside OE (and compile it using a meta-toolchain
for example)
and in the end you can easily produce a patch using git that you
integrate back into OE.

There is some documentation in the manual about this:

Eric: You should probably look at the externalsrc.bbclass since it gives
you a way to do things like this yet also build and package it with the
usual build system:

yes, this can be very usefull when you need packaging, but for
bootloader and kernel development, using the build system during
development doesn't bring any added value IMHO.
