compile and install python module failed

[Catstyle]

download release packege from https://protobuf.googlecode.com/svn/rc/protobuf-2.6.0.tar.gz
yeah, for some all we known reasons i cannot build from git source because it need to download gtest from google site

./configure && make && make install && ldconfig
protoc installed successfully, then go to install python module

cd python
export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp
export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION_VERSION=2
python setup.py build --cpp_implementation && python setup.py test --cpp_implementation && python setup.py install --cpp_implementation

indeed it said all goes well, but when i tried my app, it complained that missing pyext
ah... something wrong!
then i took a look at the protobuf egg, it DID HAVE NO pyext module
am i doing wrong?

Traceback (most recent call last):

    from google.protobuf import descriptor_pb2

ImportError: cannot import name cpp_message

it seems somewhere need to import pyext.cpp_message, then go to
https://github.com/google/protobuf/blob/master/python/google/protobuf/reflection.py#L60
i do export two environments above

Hi, how did you fix it in the end? I didn't get it. I still get the error.
Thank you.

[xfxyjwf]

@foebu, a file was missing from the setup.py script. We added that file in the fix.

[foebu]

@xfxyjwf I still get the error, though, and I downloaded the release 2.6.1. It seems that in pyext.cpp_message a pyext._message is imported, but the pyext._message module doesn't exist. I'm not an expert, though.

check that you run setup.py google_test not setup.py test

[foebu]

Now, that works. But if that is the standard test, then this readme needs to be changed: https://github.com/google/protobuf/tree/master/python
Thank you, though!

Note that in 2.6.1 release, the readme does say using "google_test":
https://github.com/google/protobuf/tree/v2.6.1/python

This has been changed in recent releases though.

My bad then, I was reading a different readme :) Sorry.
