Re: [ECOS] How to re-install newly compiled gnutools

["ariga masahiro" <ariga at link-lab dot co dot jp>]

Hello everyone,

I am sorry to sending two mails at one time.
But I am encountered next phenomoinon,
and I think it is concerned with my first inqury mail,
So I mail this as a postscript.

Correct or not, I procceede to configure-build
using /usr/local/sh-elf/ installed by (1) way.
Of course I added /usr/local/sh-elf/bin to PATH and
remained gnutools directory as it is.

As I said I succeeded configure-build using target and "net"
and made libextras.a.

But when I tried to link application program,(I append Makefile below)
I was encountered next error.
