Hi All!
Sorry for the long mail but could someone please be more specific and tell
me
what exactly BLOB looks for in a Configured Linux Kernel tree and why?
I mean could you pls confirm whether or not it needs *.c files from a
configured kernel tree.
I suppose it is logical that it should neither look for $LINUX/src/*.c files
nor should it look for $LINUX/include/linux/*.h files. Is this true?
Im asking these because i am trying to customise BLOB to my requirement and
Im facing problems.
The customisation that i did for BLOB is:
In "configure.in", I changed the --with-board=NAME to --with-board=lart.
Then in acconfig.h, I changed the #undef LART to #define LART and also
defined CPU as SA1100
Then in "configure", I changed the --with-board=NAME to --with-board=lart
and
--with-linux-prefix=/home/sridhar/linux-2.4.20 where i have a configured
Linux kernel tree
but with not all *.c files available.
The $LINUX/include/asm files are in the path:
/home/sridhar/linux-2.4.20/asm-arm/arch-sa1100
Then i type the following at the bash shell command prompt:
export CC=arm-linux-gcc
export OBJCOPY=arm-linux-objcopy
Then i run ./configure
I get the following output on the terminal:

Is there anything wrong with the configuration process?
To me that seems to be OK as i got the expected output msg but im not sure.
Pls help me.
Thank You

blob doesn't use the kernel headers ($LINUX/include/linux) per se, but it
does leverage the architecture-specific headers ($LINUX/include/asm) to get
to the defines and structures that describe the processor and peripherals.

Well, could you pls tell me as to why blob needs the Linux kernel headers?
I want to know because here, I have a configured Linux kernel source tree
without
the *.c files of the configured kernel.I have the *.h files though and all
the makefiles etc. too
with me.
When I try to configure and compile the blob with this kernel source tree
(without the *.c files)
the configuration seems to be successful but at the gmake stage i get an
error output which says
"Nothing to do for 'all' " and stops.
Could someone pls let me know what the problem is and why blob needs the
kernel headers?
Thank You
Sridhar

Blob (unfortunately) uses the kernel headers. You are correct that this is
not the best idea, not only for the reasons you mention but also because the
kernel headers change from time to time.
