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
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.
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 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(); ^ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/iosfwd:108:28: note: template is declared here class _LIBCPP_TYPE_VIS basic_istream; ^ google/protobuf/message.cc:135:67: error: implicit instantiation of undefined template 'std::__1::basic_istream<char, std::__1::char_traits<char> >' return ParsePartialFromZeroCopyStream(&zero_copy_input) && input->eof(); ^ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/iosfwd:108:28: note: template is declared here class _LIBCPP_TYPE_VIS basic_istream; ^ google/protobuf/message.cc:175:16: error: implicit instantiation of undefined template 'std::__1::basic_ostream<char, std::__1::char_traits<char> >' return output->good(); ^ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/iosfwd:110:28: note: template is declared here class _LIBCPP_TYPE_VIS basic_ostream; ^(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.
From https://github.com/paulirish/homebrew-versions-1 . Works for me!
brew install https://raw.githubusercontent.com/paulirish/homebrew-versions-1/master/protobuf241.rb I used macports
sudo port install protobuf-cpp 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
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.
