Compile a graphql-engine executable using brew and ghc-8.10.7

Note: These instructions use the path /opt/homebrew in various places, but this path may be different on your machine depending on where you have installed homebrew (for example, many older homebrew installation were installed to /usr/local). You can find out the path of your homebrew installation by running the command brew --prefix, and if the output is not /opt/homebrew, then you should replace any instances of /opt/homebrew in these instructions with the path output by brew --prefix.

1. Install ghc-8.10.7 and cabal-install via ghcup

2. Install dependencies:

   brew install google-cloud-sdk
   brew install node@14
   brew install openssl
   brew install pcre
   brew install unixodbc
   brew install libpq
   brew install mysql-client@5.7
   brew install libffi
   brew install llvm@11
   brew install mssql-tools
   

   And add them to your environment:

   echo 'export PATH="/opt/homebrew/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/bin:$PATH"' >> ~/.zshrc
   echo 'export PATH="/opt/homebrew/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc
   echo 'export PATH="/opt/homebrew/opt/node@14/bin:$PATH"' >> ~/.zshrc
   echo 'export PATH="/opt/homebrew/opt/mysql-client@5.7/bin:$PATH"' >> ~/.zshrc
   echo 'export PATH="/opt/homebrew/opt/libpq/bin:$PATH"' >> ~/.zshrc
   echo 'export PATH="/opt/homebrew/opt/llvm@11/bin:$PATH"' >> ~/.zshrc
   

3. Install console assets

   This step may require you to have python2 installed and available in your $PATH.

   cd console
   npm ci
   npm run server-build
   cd ..
   

4. Install python

   export PKG_CONFIG_PATH="/opt/homebrew/opt/libffi/lib/pkgconfig"
   export LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib"
   export CPPFLAGS="-I/opt/homebrew/opt/openssl@1.1/include"
   
   cd server
   python3 -m venv .python-venv
   source .python-venv/bin/activate
   pip3 install -r tests-py/requirements.txt
   (cd tests-py/remote_schemas/nodejs && npm ci)
   

5. Append lines below to cabal/dev-sh.project.local to allow Cabal (the Haskell build tool) to find the C dependencies you installed earlier (remembering to replace /opt/homebrew with your brew prefix if different):

   package mysql
     extra-include-dirs:
       /opt/homebrew/opt/openssl/include
       /opt/homebrew/opt/mysql-client@5.7/include
     extra-lib-dirs:
       /opt/homebrew/opt/openssl/lib
       /opt/homebrew/opt/mysql-client@5.7/lib
   
   package odbc
     extra-include-dirs: /opt/homebrew/opt/unixodbc/include
     extra-lib-dirs: /opt/homebrew/opt/unixodbc/lib
   
   package pcre-light
     extra-include-dirs: /opt/homebrew/opt/pcre/include
     extra-lib-dirs: /opt/homebrew/opt/pcre/lib
   
   package postgresql-libpq
     extra-include-dirs:
       /opt/homebrew/opt/libpq/include
       /opt/homebrew/opt/openssl/include
     extra-lib-dirs:
       /opt/homebrew/opt/libpq/lib
       /opt/homebrew/opt/openssl/lib
   
   package pg-client
     extra-include-dirs:
       /opt/homebrew/opt/libpq/include
       /opt/homebrew/opt/openssl/include
     extra-lib-dirs:
       /opt/homebrew/opt/libpq/lib
       /opt/homebrew/opt/openssl/lib
   

   Then either copy and paste the entirety of cabal/dev-sh.project.local into cabal.project.local, or create a symlink by running the command:

   ln -s cabal/dev-sh.project.local cabal.project.local
   

   (Copying and pasting allows you to add local projects overrides, which may be needed if you are are planning to make changes to the graphql-engine code, but is not required for simply compiling the code as-is).

6. Write the version number of the graphql-server that you are intending to build to the file server/CURRENT_VERSION. For example if you are building v2.6.1 then you can run the following command:

   echo '2.6.1' > server/CURRENT_VERSION
   

   This version number is used for the output of graphql-engine --version in your compiled binary, and it also used when fetching the frontend assets for the console from the CDN when running the server (if you do not specify --console-assets-dir to make it load from a locally compiled version).

7. Building the server should now work:

   cabal v2-update
   cabal v2-build exe:graphql-engine -j4
