Cross-compiling for ARM

[Jaap Boender <jaapb%kerguelen.org@localhost>]

Hi list,

I'm trying to set up cross-compilation for pkgsrc from amd64 to arm 
(compiling webkit-gtk2 on the pinebook is quite slow...). This is 
running on a NetBSD/amd64-current box (8.99.31), and I'm using the 
instructions from doc/HOWTO-use-crosscompile.

I've set up the environment (tools, distribution and /etc/mk.conf) as 
suggested in that document, and am now trying to compile 
cross/cross-libtool-base. This fails (in pkgtools/cwrappers) with the 
error represented below.

I haven't the foggiest idea what is going on here or how to debug it - 
is anybody able to give some advice?

thanks!

  Jaap
