How do I install protobuf 2.5 on Arch Linux for compiling hadoop 2.6.0 using maven 3.3.1?

Question

Am looking for installing protobuf 2.5.0 on Arch Linux, so that protoc-2.5.0.so is installed on the OS, so that I can go ahead with building hadoop 2.6.0 from source and make my life easy! :)

BTW, protobuf 2.6.0 does not compile when hadoop is built from source I have tried that as well. Ubuntu 14.04 comes with protoc 2.5.0. I DO NOT want to use Ubuntu.

Please check the screenshot first (there is no protobuf 2.5.0), since the problem lies there.. I guess am getting the following exception, I am aware that protoc is not installed in arch linux currently.

[ERROR] Failed to execute goal org.apache.hadoop:hadoop-maven-plugins:2.6.0:protoc (compile-protoc) on project hadoop-common: org.apache.maven.plugin.MojoExecutionException: 'protoc --version' did not return a version -> [Help 1]

Please help me out, since, I have spent 4 hours every day from two days, with no luck.

Answer 1

Compiling Google's protobuf is pretty easy. I originally found out how to do it on this blog post while compiling hadoop myself.

But here is my version:

$ cd /usr/local/src/
$ wget https://github.com/google/protobuf/releases/download/v2.5.0/protobuf-2.5.0.tar.gz
$ tar xvf protobuf-2.5.0.tar.gz
$ cd protobuf-2.5.0
$ ./autogen.sh
$ ./configure --prefix=/usr
$ make
$ make install
$ protoc --version

Install protobuf for java

$ cd java
$ mvn install
$ mvn package

You should be good to go.

To enable you to install different versions of protobuf, install stow then change ./configure --prefix=/usr to ./configure --prefix=/usr/local/stow/protobuf-2.5.0

Then link protobuf into your system with stow:

$ cd /usr/local/stow
$ stow protobuf-2.5.0

Note: stow uses /usr/local/bin by default. Make sure thats in your $PATH

To unlink that version of protobuf,

$ stow -D protobuf-2.5.0

Hope this helped.

Answer 2

I wonder why the above answer got downvoted,even I had to perform few more steps (in addition to the accepted answer by Rudker) to get protobuf 2.5 installed on Ubuntu Xenial.

Leaving the additional steps here for everyone's benefit:

apt-get install autoconf in response to the error : ./autogen.sh: autoreconf: not found for command : ./autogen.sh

apt-get install libtool in response to the error : autoreconf: libtoolize is needed because this package uses Libtool for command : ./autogen.sh

apt install g++ in response to the error : configure: error: C++ preprocessor "/lib/cpp" fails sanity check for command : ./configure --prefix=/usr
