From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gary Thomas To: Rene.Affourtit@pemstar.nl Cc: ecos-discuss@sourceware.cygnus.com, aknecht@cimsi.cim.ch Subject: RE: [ECOS] Threading on EDB7211 Date: Mon, 19 Jun 2000 04:11:00 -0000 Message-id: References: X-SW-Source: 2000-06/msg00183.html The very first thing to look at is the tools you are using to build eCos. The sourceware 'binutils' package _was_ broken. Any snapshots from late May through early June will not build a running eCos on ARM platforms.
