New issue 2364: gctransformer issue while trying to translate pypy to ARM
https://bitbucket.org/pypy/pypy/issues/2364/gctransformer-issue-while-trying-to

Dewald Pretorius:

I've followed the guide from here: http://rpython.readthedocs.io/en/latest/arm.html#arm

All steps were successful, up to "pypy /home/username/pypy2-v5.3.1-src/rpython/bin/rpython -O1 --platform=arm target.py"

which fails as follows:

I'd really appreciate any assistance as our tests have demonstrated a seven factor speed increase in using pypy over python2.7.

I have made sure that I have all the dependencies installed that I need to build pypy from source - by building pypy from source.

I've also tried translating the full interpreter

Any advise would be really appreciated.
