[ECOS] configure and cross compilation

[ECOS] configure and cross compilation

[Jacek Poplawski]

I am trying to compile CVS version of ecos/RedBoot.

How to specify which toolchain configure should use?
I tried that way:

../ecos/configure --target=xscale-elf

But used compiler name is still "gcc", not "xscale-elf-gcc".
Should I make symbolic links?

Could you point me to the documentation describing how to compile current
version of RedBoot?

This is not how you build an eCos application [RedBoot is just
such an eCos application]

The basic steps are:
   0.1 Set up your [cross-development] tool chain
   0.2 Set up 'ecosconfig' and/or 'configtool'
       These steps need to be executed only once.  More information can be
       found at: http://ecos.sourceware.org/getstart.html
   0.3 Download the latest eCos sources
       It's recommended to download eCos from CVS, rather than the older 2.0
       release.
   1.0 Create the basic eCos configuration.  This involves
       a) selecting a target and environment template
       b) optionally modifying the eCos configuration
       c) generate a build tree
   2.0 Build your application, using make

For example, to build eCos for the iq80321 (ARM XScale board)
   % mkdir ecos_iq80321
   % cd ecos_iq80321
   % ecosconfig new iq80321 redboot
   % ecosconfig tree
   % make

Hello Gary,

Yes, later last afternoon I was able to compile it in usual way, with
ecosconfig and make. I just have seen ./configure so I thought that's the
current proper way.

I do the same, but I use command line arguments (like --srcdir) instead
environment variables. I also use very old ecosconfig (from RedBoot much
older than 2.0).

I build RedBoot for ixp425, put it on ixp2801 board and of course crashed
it :) But at least now I know how to build current version of RedBoot and
I can start searching for differences with 2801.

Thanks for help.
