If you downloaded this package from PyPI +or some other Python-specific source, you may have received only the +Python part of the code. In this case, you will need to obtain the +Protocol Compiler from some other source before you can use this +package. + +Development Warning +=================== + +The Python implementation of Protocol Buffers is not as mature as the C++ +and Java implementations. It may be more buggy, and it is known to be +pretty slow at this time. If you would like to help fix these issues, +join the Protocol Buffers discussion list and let us know! + +Installation +============ + +1) Make sure you have Python 2.6 or newer. If in doubt, run: + + $ python -V + +2) If you do not have setuptools installed, note that it will be + downloaded and installed automatically as soon as you run `setup.py`. + If you would rather install it manually, you may do so by following + the instructions on [this page](https://packaging.python.org/en/latest/installing.html#setup-for-installing-packages). + +3) Build the C++ code, or install a binary distribution of `protoc`. If + you install a binary distribution, make sure that it is the same + version as this package. If in doubt, run: + + $ protoc --version + +4) Build and run the tests: + + $ python setup.py build + $ python setup.py test + + To build, test, and use the C++ implementation, you must first compile + `libprotobuf.so`: + + $ (cd .. && make) + + On OS X: + + If you are running a Homebrew-provided Python, you must make sure another + version of protobuf is not already installed, as Homebrew's Python will + search `/usr/local/lib` for `libprotobuf.so` before it searches + `../src/.libs`. + + You can either unlink Homebrew's protobuf or install the `libprotobuf` you + built earlier: + + $ brew unlink protobuf + + or + + $ (cd .. && make install) + + On other *nix: + + You must make `libprotobuf.so` dynamically available. You can either + install libprotobuf you built earlier, or set `LD_LIBRARY_PATH`: + + $ export LD_LIBRARY_PATH=../src/.libs + + or + + $ (cd .. && make install) + + To build the C++ implementation run: + + $ python setup.py build --cpp_implementation + + Then run the tests like so: + + $ python setup.py test --cpp_implementation + + If some tests fail, this library may not work correctly on your + system. Continue at your own risk. + + Please note that there is a known problem with some versions of + Python on Cygwin which causes the tests to fail after printing the + error: `sem_init: Resource temporarily unavailable`. This appears + to be a [bug either in Cygwin or in + Python](http://www.cygwin.com/ml/cygwin/2005-07/msg01378.html). + + We do not know if or when it might be fixed. We also do not know + how likely it is that this bug will affect users in practice. + +5) Install: + + $ python setup.py install + + or: + + $ (cd .. && make install) + $ python setup.py install --cpp_implementation + + This step may require superuser privileges. + NOTE: To use C++ implementation, you need to export an environment + variable before running your program. See the "C++ Implementation" + section below for more details. + +Usage +===== + +The complete documentation for Protocol Buffers is available via the +web at: + + https://developers.google.com/protocol-buffers/ + +C++ Implementation +================== + +The C++ implementation for Python messages is built as a Python extension to +improve the overall protobuf Python performance. + +To use the C++ implementation, you need to install the C++ protobuf runtime +library, please see instructions in the parent directory. |
