2> In make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage  I get error, CROSS_COMPILE=arm-linux-gnueabi works; any idea why ?

Ans to 1st point is here
https://github.com/androportal/linux-on-aakash/blob/master/getting_file_system_ready.rst

2nd point I didn't get it. May be arm-linux-gnueabi is not in your path. Try typing arm and use tab completion to verify before running this make command. You know these better :-)

yes I realized that is silly point

also secondly, I m getting familiar with compiling different configurations... Each time I compile it takes around 7mins to cook with -j2 flag which is frankly one coffee break...

To reduce this, I tried clustering with my netbook using Distcc but it is throwing error reporting about missing arm libs even when my netbook already has gcc-arm/cpp-arm toolchain installed.

For regular compilation distcc works and saves significant time.

Any ideas why it is not working for cross compilation ?

[Srikant]

No idea, never tried clustering !

[isachin]

are you compiling across network ? what cmds have you used ?

please also try crosstool-ng

[isachin]

try CROSS_COMPILE=arm-none-linux-gnueabi- uImage also

as stated before, I get an error with arm-none-linux-gnueabi

manoj@manoj-Lenovo-G550:~/linux-sunxi$ make -j2 ARCH=arm CROSS_COMPILE=arm-linux-none-gnueabi- uImage

make: arm-linux-none-gnueabi-gcc: Command not found

I read briefly about crosstool-ng; I am not able to co-relate with situation. Distcc itself isnt a compiler, its just a wrapper for C compiler,

It sends out pre-processed file to other machines in network for them to compile

just to basics sometimes we do some silly mistakes ... are you sure your networking interfaces are properly setup ?

>> Of course, the fact that I am able to compile python 3.2 source (and also the fact that I can ping my netbook IP) proves setup is correct and working

Here's the stat:

with distcc => make time 1:36:133

without distcc => make time 1:42:089
