Installing Google Protocol Buffers on mac

问题:

I would like to install the older version of Google Protocol Buffers (protobuf-2.4.1) on mac using Terminal command line. I tried with brew install protobuf, but the latest version 2.5.0 has been installed. Is it possible to install the older version from terminal.

Thanks

回答1:

There are some issues with building protobuf 2.4.1 from source on a Mac. There is a patch that also has to be applied. All this is contained within the homebrew protobuf241 formula, so I would advise using it.

To install protocol buffer version 2.4.1 type the following into a terminal:

brew tap homebrew/versions
brew install protobuf241

If you already have a protocol buffer version that you tried to install from source, you can type the following into a terminal to have the source code overwritten by the homebrew version:

brew link --force --overwrite protobuf241

Check that you now have the correct version installed by typing:

protoc --version

It should display 2.4.1

This is not via brew, but the end result is the same.

1. Download the protobuf-2.4.1 from https://protobuf.googlecode.com/files/protobuf-2.4.1.tar.gz
2. Extract the tar.gz file.
3. $cd ~/Downloads/protobuf-2.4.1
4. $./configure
5. $make
6. $make check
7. $sudo make install
8. $which protoc
9. $protoc --version

Steps 4-7 are from the README.txt file from the protobuf tarball.

It's a new year and there's a new mismatch between the version of protobuf in Homebrew and the cutting edge release. As of February 2016, brew install protobuf will give you version 2.6.1.

If you want the 3.0 beta release instead, you can install it with:

brew install --devel protobuf

From https://github.com/paulirish/homebrew-versions-1 . Works for me!

brew install https://raw.githubusercontent.com/paulirish/homebrew-versions-1/master/protobuf241.rb

For some reason I need to use protobuf 2.4.1 in my project on OS X El Capitan. However homebrew has removed protobuf241 from its formula. I install it according @kksensei's answer manually and have to fix some error during the process.

During the make process, I get 3 error like following:

google/protobuf/message.cc:130:60: error: implicit instantiation of undefined template 'std::__1::basic_istream<char, std::__1::char_traits<char> >'

  return ParseFromZeroCopyStream(&zero_copy_input) && input->eof();

                           ^

(Sorry, I dont know how to attach code when the code contains '`' )

If you get the same error, please edit src/google/protobuf/message.cc, add #include <istream> at the top of the file and do $ make again and should get no errors. After that do $ sudo make install. When install finished $protoc --version should display the correct result.

I used macports

sudo port install protobuf-cpp

回答7:

brew install --devel protobuf

If it tells you "protobuf-2.6.1 already installed": 1. brew uninstall --devel protobuf 2. brew link libtool 3. brew install --devel protobuf

回答8:

FWIW., the latest version of brew is at protobuf 3.0, and doesn't include any formulae for the older versions. This is somewhat "inconvenient".

While protobuf may be compatible at the wire level, it is absolutely not compatible at the level of generated java classes: you can't use .class files generated with protoc 2.4 with the protobuf-2.5 JAR, etc. etc. This is why updating protobuf versions is such a sensitive topic in the Hadoop stack: it invariably requires coordination across different projects, and is traumatic enough that nobody likes to do it.

you can install from official link page provided by google http://google.github.io/proto-lens/installing-protoc.html
