pycapnp version 0.5.12 ships capnp 0.5.3.1 but clang 4 / capnp::Kind still error

[breznak]

I'm using the latest pycapnp release from pypi, which is 0.5.12. According to the changelog it ships capnp 0.5.3.1, which contains a fix for compilation with clang 4.x:
capnproto/capnproto#433

However, I'm still getting the same error that was supposed to be fixed. Is the problem in pycapnp, capnp, or somewhere else?

Thank you,

[jparyani]

Can you attach the output of pip install -v or similar?

This is on Ubuntu, in virtualenv, otherwise capnp is and has been working fine

[jparyani]

That looks like a successful install. What is the error you're seeing?

It looks like you may be picking up an older version of pycapnp than you think? pip install pycapnp does seem to work for you, so it doesn't seem to be a problem there.

Can you get the nupic install to do a verbose build and check versions in the output?

[breznak]

It looks like you may be picking up an older version of pycapnp than you think?

Thank you! You're correct, for some reason we ship the tarball and it was at the 0.5.3(not .1) version.

Should pycapnp enforce (check for) the exact capnp version it's supposed to run with? To avoid problems like this.

[chaoflow]

It feels like this issue could be closed.

[breznak]

Thank you for leading me through the debug process! 👍
