Re: cross-compiling various packages for ARM [GishPuppy]

[<idatum%comcast.net@localhost>]

Another option is distcc. I've successfully cross compiled packages (e.g. 
python2.6) using distcc on my TS7200 (evbarm).   There's a how-to you can 
read in the pkgsrc/doc dir:
HOWTO-crosscompile

It does mean you need to have pkgsrc and compiler tools on the device 
though.

Subject: cross-compiling various packages for ARM [GishPuppy]

Dear all,

I've been playing with a SheevaPlug. I was able to have a fully functional 
system. However, now I'd like to add different "packages", like wget, zsh, 
etc. I cannot compile these packages directly on the Sheeva, it's damn too 
slow, so I tried to cross-compile, without success. Here is what I did for 
wget:

Until here, it works like a charm, but as soon as I do a "make", everything 
breaks up.

I must be doing something wrong, but since I am not very experienced in 
cross compilation, I'd need a little help. Would it be possible to do a sort 
of chroot or so ?

Note that I am running:

> uname -a
Linux computer 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 
i686 i686 i386 GNU/Linux


Thanks a lot for your help.
