[okl4-developer] building oklinux for versatile

[Clément Mazin]

Yes I see this but i have another error :

/home/nizam/OKL4/okl4_3.0/cells/linux/SConscript:329 Error: 
KengeEnvironment instance has no attribute 'Ext2FS'



I tryed to remove the -f option in the command genext2fs and keep the 
definition on genext2fs : there is no error but I can't simulate the image.
