Jack,
I just tried with latest poky master built out toolchain and remote debug with
latest Eclipse plug-in has no problem. My host is 32bit Ubuntu, but I don't
think that makes any difference. So how up to date is your poky meta data,
mine is as of this afternoon that contains 2 bug fixes that relevant to
meta-toolchain build. Also, seems you're using the build system derived
toolchain? If so, I can give that a try...
Thanks,
Jessica

Any ideas, it seems as though the Python wasn't built with Unicode
support but I can't tell if it is using the bitbake built python or
host python...

Hi Jessica,
Thanks for your reply.
I am using the build system derived toolchain. I am using the latest
poky.git as of 9:22am GMT 9th Jan. I am using the eclipse-plugin master
branch. I tried again this morning and encountered the same error.
To run the eclipse plugin I am using the method of adding the source
code to the eclipse project and then right clicking and running as an
eclipse program. However I believe the issue is either with my Python,
or with some other incompatibility in the script.
Best Regards,
Jack.
