RE: [ECOS] Help! on building ecosconfigure

["Narayana, Venkat A." <NarayVA at nsc-msg01 dot network dot com>]

Hi,
Thanks for the reply.After you have pointed out, that my 'ld' is from
arm-linux, instead of arm-elf/xscale-elf,i looked at my tools/biin and
realised
that xscale-elf-gcc => arm-linux-gcc. So, i changed xscale-elf-gcc =>
arm-elf-gcc
and did a 'make' in my redboot.ROM directory, to build ROM startup files.
Guess what!!! It built the binaries!. BUT, after i did 'make clean' and then
did
'make'( i want ot build ROM Startup bin files),now, i got a whole bunch of
new 
errors like below.

To answer your query on what i used to configure:
   host=i686-pc-linux
   target=arm-elf
   prefix = /home/users/ecoscvs/tools

The following info may be usefule for you;
xscale-elf-gcc --version = 3.0
xscale-elf-gcc -dumpmachine = arm-elf
gcc --version = 3.0
gcc -dumpmachine = i686-pc-linux-gnu

Why am i getting these new errors/ does my path is bad? 
And why did in the mixed up case of gcc and ld, binaries got built.

They are basically the same, but slightly different configurations.

>From the messages below, it does not look like 'xscale-elf-gcc' is calling
the appropriate 'xscale-elf-ld' file.  When you built these, what
"configure"
line did you use?  In particular, what were the values for --prefix and
--host-prefix?

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This should be the xscale-elf version, not any arm-linux one.
