this does not work:

also do not work:

protobuf/src/README.md at v25.1 · protocolbuffers/protobufGitHub

If Bazel cannot be located, do following, reference this thread, we are using david's method

sudo apt install apt-transport-https curl gnupg
curl -fsSL https://bazel.build/bazel-release.pub.gpg | gpg --dearmor >bazel-archive-keyring.gpg
sudo mv bazel-archive-keyring.gpg /usr/share/keyrings
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/bazel-archive-keyring.gpg] https://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list

bazel build :protoc :protobuf

sudo cp bazel-bin/protoc /usr/local/bin

Verify install correctly:

$ protoc --version
libprotoc 26.0

$ whereis protoc
protoc: /usr/local/bin/protoc

Also download the release here and move the include folder to /usr/local/include/google

Releases · protocolbuffers/protobufGitHub

DOES NOT WORK:

sudo apt install protobuf-compiler

Download the prebuilt file, copy the include/google folder to /usr/include

sudo cp -r ./include/google/ /usr/include/

Also need to download source, and copy the protobuf-25.1/src/google/protobuf/stubs folder to there

cd ~/Downloads/protobuf-25.1/src/google/protobuf/
sudo cp -r ./stubs/ /usr/include/google/protobuf/

FINALLY WORKS

sudo apt install autogen autoconf libtool

git clone https://github.com/protocolbuffers/protobuf.git
cd protobuf
git checkout v3.6.1

i think this works up to 3.12.3, havent tried

instruction is here

git submodule update --init --recursive
./autogen.sh

./configure --prefix=/usr
make -j8
make check
sudo make install
sudo ldconfig # refresh shared library cache.
