# 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](https://www.haskell.org/ghcup/)
2. Install dependencies:
```sh
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:
```sh
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.
```sh
cd console
npm ci
npm run server-build
cd ..
```
4. Install python
```sh
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):
```sh
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:
```sh
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:
```sh
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:
```sh
cabal v2-update
cabal v2-build exe:graphql-engine -j4
```
