  1. Best Answer

    See https://github.com/protocolbuffers/protobuf/blob/master/src/README.md:

    Prerequesites

    $ sudo apt-get install autoconf automake libtool curl make g++ unzip

    Installation

    1. From this page, download the protobuf-all-[VERSION].tar.gz.
    2. Extract the contents and change in the directory
    3. ./configure
    4. make
    5. make check
    6. sudo make install
    7. sudo ldconfig # refresh shared library cache.

    Check if it works

    $ protoc --version
libprotoc 3.6.1

  3. If you are a non-C++ user and/or don't want to compile it yourself, the simplest way to install the current version of protoc is to download a pre-built binary from the release page.

    https://github.com/protocolbuffers/protobuf/releases

    To install, simply place this binary somewhere in your PATH (e.g. /usr/local/bin).

    (If you intend to use the included well known types then don't forget to copy the contents of the 'include' directory somewhere as well, for example into /usr/local/include/.)

  4. You can download binary from the source code and use next commands

    sudo rm -rf ./protoc
unzip protoc-3.10.1-linux-x86_64.zip -d protoc
chmod 755 -R protoc
BASE=/usr/local
sudo rm -rf $BASE/include/google/protobuf/
sudo cp protoc/bin/protoc $BASE/bin 
sudo cp -R protoc/include/* $BASE/include

    Change your base to /usr/, or /usr/loca/, or anything else in your PATH.

  5. 1) Download binary from the url https://github.com/protocolbuffers/protobuf/releases

    2) extract and keep the directory at particular location (/user/app/protoc)

    3) add the entry in /usr//.bash_profile as export PROTOC_HOME=/user/app/protoc export PATH=$PROTOC_HOME/bin:$PATH

    4) refresh file $source /usr/<username>/.bash_profile

    Other option is run the following command one by one after downloading the repository :

    sudo rm -rf ./protoc

    unzip protoc-3.10.1-linux-x86_64.zip -d protoc

    chmod 755 -R protoc

    BASE=/usr/local

    sudo rm -rf $BASE/include/google/protobuf/

    sudo cp protoc/bin/protoc $BASE/bin

    sudo cp -R protoc/include/* $BASE/include

  6. Use this if you are having errors like

    google/protobuf/descriptor.proto: File not found.
    google/protobuf/duration.proto: File not found.
    google/protobuf/timestamp.proto: File not found.

    PROTOC_ZIP=protoc-3.7.1-linux-x86_64.zip
curl -OL https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
sudo unzip -o $PROTOC_ZIP -d /usr/local 'include/*'
rm -f $PROTOC_ZIP

    This is useful when you are doing generation for go using protoc-gen-go as it requires the base proto files to be present in default include folders
