Re: cross compiling of bash for 8xx

["RAJESH.B.V" <rajeshbv@trinc.com>]

Hi Marcus,

Thank you for providing the script to compile bash.

Now i am able to compile the bash with some changes.
it gave some error while compiling the  malloc to choose from gnu_malloc
or   gcc_malloc
So i turned off both the options and compiled.
But still it is not executing.
After completing all the checkings at the boot time the board is hanging
without giving the prompt.
I have compiled one more shell called "sash" and able to execute it.
At the same time i have compiled the Busybox and it is also executing under
Sash shell.
I found some binaries which are for PPC8xx at  mvista.com site. From that
site also i have downloaded the bash binary and failed to get the shell.
I did not able to understand why some binaries are executing which are
compiled with the same compiler and some are not...
I am using GCC version 2.95.2 and Glibc version 2.
I checked both the binaries which are working and failed with a hex editor .
They were showing the same shared libraries  as    " /lib/ld.so.1"
and using some  #defines in   "libc.so.6."

Will be there any difference between the binaries compiled with cross
compiler and straight compiler. i feel there should not be.

Thanks in regards,
--Rajesh
