TypeError: Expected unicode, got EncodedString when cythonizing rados.pyx from Ceph 12.0.x

[Andy Bailey]

Hi All,

 I'm troubleshooting a problem that I'm having building the ceph distributed filesystem package from source; the package includes a handful of cythonized python modules. I am clueless about Cython, and I expect that this is probably an issue that I created when building either the Python or Cython sources, but I'm having trouble interpreting this stack stack trace, which I suspect contains a clue that I don't see.

 Initially I thought the issue might be with the content of the rados.pyx file, so I thought I'd try commenting out virtually the entire contents of the .pyx file and still get the same results. Might someone give me a clue? :) 

I'm using python 2.7.13 + cython 0.25.2

Thanks in advance!!

as is so often the cases, moments after throwing in the towel and begging for help, I discovered that I'd inadvertantly replaced some double quotes with angle brackets to try to work around an include dir ordering issue in the rados.pyx file :)

Thanks and hopefully the next poor devil who makes this mistake will find this post :)

Thanks for following up. Regardless, we should probably be giving a much better error than this. Do you have a minimal reproducible example?
