Forgive my confusion but I haven't been working with these tools for very long.
It appears from the output (included in my original email) that the components that are causing the problem are those that were distributed with gnuarm 4.1.1. I built eCos and my application using that very same arm-elf-gcc. It's not completely clear to me why all these things are being linked in (e.g. _udivsi3.o, _umodsi3.o, etc.) but I did not build the arm-elf-gcc compiler. So, it appears that after going to some effort to get things compiling with this version of arm-elf-gcc so that I can build for the armv5te instruction set I am unable to link my application because of components apparently built with FPA that are distributed with the compiler. Is this accurate or am I missing something? It just seems odd that I needed to get this newer version of the compiler in order to compile for VFP but I can't link my application becuase of components that came with the compiler that were built with FPA. > Subject: Re: [ECOS] FPA vs VFP? > From: [EMAIL PROTECTED] > To: [EMAIL PROTECTED] > CC: [email protected] > Date: Wed, 28 Nov 2007 07:54:23 -0600 > > This usually means that you built some stuff with a compiler that uses > FPA and you are trying to link in objects that were built with a > compiler that uses VFP. > > I see this alot with hard-float and soft-float merging. > > ie. people try to use a gcc built with hard-float and try to pass > soft-float to an app. > > Your toolchain is built with FPA, whereas your app is trying to be built > with VFP > > On Wed, 2007-11-28 at 08:23 -0500, C B wrote: >> >> I think I've very close to finally getting my eCos application in working >> order.
