Generating Protobuf Files

Android requires protobuf 2.5.0 to auto generate the files. To generate the files just run make.

Note: Protobuf 2.5.0 will have to be aliased to protoc25.

Mac Installation Instructions

Protobuf can be installed using brew but this will only get versions > 3. To install protobuf 2.5.0 follow these steps:

wget https://github.com/google/protobuf/releases/download/v2.5.0/protobuf-2.5.0.tar.bz2
tar xvf protobuf-2.5.0.tar.bz2
cd protobuf-2.5.0
./configure CC=clang CXX=clang++ CXXFLAGS='-std=c++11 -stdlib=libc++ -O3 -g' LDFLAGS='-stdlib=libc++' LIBS="-lc++ -lc++abi" --disable-shared --prefix='<PATH TO A DIRECTORY>'
make -j4
make install

This will compile and build the binary at PATH TO A DIRECTORY which you specified in the ./configure command. Next you need to move it to your local bin:

cd <PATH WHERE YOU INSTALLED PROTOBUF 2.5>/bin
chmod +x ./protoc
mv ./protoc /usr/local/bin/protoc25
