Re: [linuxsh-dev] Compiling Linux kernel on ST407750 Overdrive board

[Stuart M. <Stu...@st...>]

Hi there

There are a couple of problem here:

 - It looks like you are using an older version of the gcc tools.
   The building-source.php3 page should probably be maked as obsolete
   now, as most people have now migrated to the newer tools described
   in:
     http://linuxsh.sourceforge.net/docs/abe/20010320-gcc2.97/README_E.ph=
p3
   (follow the links at the end of the 'Documents' page on linuxsh.sf.net=
).

 - A few months ago we decided to drop support for the 7750 Overdrive
   in the Linux kernel sources (we really don't want to have to continue
   to support it any longer than necessary - especially now we have ST40
   based boards available). So what is in the CVS repository on SourceFor=
ge
   is only some of the code needed.

You are probably better off looking at:
  ftp://ftp.linuxsh.st.com/pub/linuxsh/release-0.4
There you will find RPMS and SRPMs for the compiler, and kernel, which ha=
s
already been patched to support the 7750 Overdrive.

Good luck

Stuart
