My latest computer is Windows 7 64 bit. I installed 64 bit cygwin so that
I can continue developing my ecos project. The "Installing Cygwin for use
with eCos" page specifically says to select libmpfr1 (and others). But
the 64 bit cygwin installer only has libmpfr4. I selected that package
and continued with the installation.
After installing the arm-eabi cross compiler, I find that it will not run.
At a cygwin prompt, I typed "/op/ecos/gnutools/arm-eabi/bin/arm-eabi-gcc
-version" and got nothing back before a new prompt. It seems that
libmpfr1 is required for the eCos toolchains to run.
Can anyone tell me how to fix this problem?
Thank you,
Stephen Finney

Yes, libmpfr1 is required.

The Cygwin-hosted eCos toolchains were built before 64-bit Cygwin was
available. These toolchains run just fine with a 32-bit Cygwin
installation on 64-bit Windows 7 so, as a workaround, you might attempt
a parallel installation of 32-bit Cygwin (including libmpfr1) on your
new PC. It would be helpful to report back to this list.
In the longer term, we will need to re-build the toolchains against
libraries provided by 64-bit Cygwin.
I hope this helps...

John is right, just use Cygwin 32-bit isntead of 64-bit. There might
be an issue with building in Windows with the newest TCL8.5 libary and
cygwin1.dll that use the same namespace.
This helped the colleagues having this problem recently:

John and Max,
After I installed the 32 bit cygwin and applied the changes referenced in
Max's email I can now build ecos on my new computer. Thank you both for
your help.
