Hi,

hope anybody can help.

I have the Cirrus Logic Evaluation Board EDB7211. I tried running eCos 1.3.1
under WinNT. To do this I need a running arm toolchain.

So I downloaded the neccessary sources (binutils, gcc-core, gcc-g++,
insight). binutils compiles without errors. When compiling gcc i got the
following error messages:

In file included from config/arm/aout.h:301,
                 from config/arm/elf.h:354,

Can anybody help? Or is there anywhere on the net a running binary arm
toolchain for cygwin under WinNT?

Thanks for your help.

bye,
Thomas

Oh dear... :) If you look through the archive of this list, you'll see that 
I struggled with this one for a long time too.

I can email you my Win32 toolchain as a zipfile (just unzip it to 
cygwin/tools) if you want. It is an arm-elf toolchain based around gcc 
2.95.2 (so it does NOT support Thumb). At this time I do not believe there 
is any way to get gcc's thumb support working under cygwin; I tried for 
months (off and on) and although it's possible eventually to build 
something (by manually cutting out bits of source files that don't compile 
properly), the result is non-functional.

I strongly urge you to move to Linux, which was the advice I was given very 
early on here on this list. I tried and tried to get Win32 working right, 
but I gave up last week sometime. Although it is very inconvenient to some 
people (including me) to have to dual-boot multiple OSs, Linux is by far 
easier to work with for this stuff. It's also much faster; it seems that 
every time you run a cygwin binary it has to reload a bunch of DLLs or 
something.

This is almost certainly a problem with spurious carriage returns.
Please see the relevant FAQ entry at

I have been able to get the cygwin / gnu toolchain running under Win NT
2000. Make sure you use the net release of the cygwin tools. I followed the
directions on the eCos website for building the tools under Win32. I am also
able to build the CVS version of eCos under NT 2000.

How did you manage to get _thumb_ support working under Cygwin? gcc 2.95.2 does
not support thumb properly according to Red Hat's instructions. The current
snapshot of gcc doesn't build under cygwin.

Sorry about the confusion. What I meant was that I was able to get the arm
tools working under NT 2000 but not the thumb support. I tried playing with
the thumb support for a week but after reading about your struggles with it
I gave up on it. I don't need thumb support for the next little while so I'm
hoping it gets fixed by the time I do need it.

fyi...Jonathan your posting are coming in as root.
