gg Build Status

Build directions

To build gg you need the following packages:

  • gcc >= 7.0
  • protobuf-compiler, libprotobuf-dev >= 3.0
  • libcrypto++-dev >= 5.6.3
  • python3
  • libcap-dev
  • libkeyutils-dev
  • libncurses5-dev
  • libboost-dev
  • libssl-dev
  • autopoint
  • help2man
  • texinfo
  • automake
  • libtool
  • pkg-config
  • libhiredis-dev

You can install this dependencies in Ubuntu (17.04 or newer) by running:

sudo apt-get install gcc-7 g++-7 protobuf-compiler libprotobuf-dev \
                     libcrypto++-dev libcap-dev libkeyutils-dev \
                     libncurses5-dev libboost-dev libssl-dev autopoint help2man \
                     libhiredis-dev texinfo automake libtool pkg-config

To build gg, run the following commands:

make -j$(nproc)
sudo make install


Environment Variables

To use gg, the following environment variables must be set:

  • GG_MODELPATH => absolute path to <gg-source-dir>/src/models/wrappers.
    • S3: s3://<bucket-name>/?region=<bucket-region>
    • Redis: coming soon.
  • GG_LAMBDA_ROLE => the role that will be assigned to the executed Lambda. functions. Must have AmazonS3FullAccess and AWSLambdaBasicExecutionRole permissions.
  • AWS_REGION => your AWS region, where the functions are installed

Installing the Functions

After setting the environment variables, you need to install gg functions on AWS Lambda. To do so:

cd src/remote/
make ggfunctions


To build mosh using gg, first we checkout the mosh source code:

git clone

Make sure that you have all the dependencies for building mosh. In Ubuntu, you can run:

sudo apt-get install -y automake libtool g++ protobuf-compiler libprotobuf-dev \
                        libboost-dev libutempter-dev libncurses5-dev \
                        zlib1g-dev libio-pty-perl libssl-dev pkg-config

Inside the mosh directory, first you need to prepare mosh to build:



gg-init # create .gg directory
gg-infer make -j$(nproc) # creates the thunks

Now, to actually compile mosh-server on AWS Lambda with 100-way parallelism, you can execute:

gg-force --engine=lambda --jobs 100 --status src/frontend/mosh-server
