Re: compat_linux

Hi
	Check that you have :

	/emul/linux/etc/ld.so.conf
	/emul/linux/bin/ldconfig	(or sbin, or anywhere)
	/emul/linux/bin/ldd		(usefull but not a must)
	/emul/linux/lib/ld.so
	/emul/linux/lib/ld-linux.so.1

you'll also need :

	/emul/linux/lib/libc.so.x	(x = the latest version)
	/emul/linux/lib/libm.so.x

and for X (a minimal set):

	/emul/linux/lib/libICE.so.x
	/emul/linux/lib/libSM.so.x
	/emul/linux/lib/libX11.so.x
	/emul/linux/lib/libXpm.so.x
	/emul/linux/lib/libXt.so.x

(or be organized and put that at usr/X11R6/lib, usr/lib, usr/local/lib, etc)

begin with that and, helped by ktrace/kdump test to run the linux app and see
what more it needs. You can also use ldd.

For the first time, you don't need to run ldconfig, just try to run linux app
(some linux apps will run without installing anything under emul)
