I initially thought as long as Lagom is not built >= 9 would be fine,
but LagomCore is always built for the code generators.

Ensure your gcc version is >= 9 with `gcc --version`. Otherwise, install it (on Ubuntu) with:
Ensure your gcc version is >= 10 with `gcc --version`. Otherwise, install it.
On Ubuntu it's in the repositories of 20.04 (Focal) - add the `ubuntu-toolchain-r/test` PPA if you're running an older version:
```bash
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get install gcc-9 g++-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 900 --slave /usr/bin/g++ g++ /usr/bin/g++-9
```
On Debian you can install it by switching to the Debian testing branch:
On Debian you can use the Debian testing branch:
```bash
sudo echo "deb http://http.us.debian.org/debian/ testing non-free contrib main" >> /etc/apt/sources.list
sudo apt update
```
Afterwards you can install gcc-9 with apt like:
Now on Ubuntu or Debian you can install gcc-10 with apt like this:
```bash
sudo apt install gcc-9 g++-9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 900 --slave /usr/bin/g++ g++ /usr/bin/g++-9
sudo apt install gcc-10 g++-10
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 900 --slave /usr/bin/g++ g++ /usr/bin/g++-10
```
If you don't want to stay on the testing branch you can switch back by running:

*Lagom* is a Swedish word that means "just the right amount." ([Wikipedia](https://en.wikipedia.org/wiki/Lagom))
## Prerequisites
You'll need a compiler as capable as the one used for the toolchain - which might differ from the compiler you used *to compile* the toolchain. Check `GCC_VERSION` in [`BuildIt.sh`](../../Toolchain/BuildIt.sh).
## Fuzzing
Lagom can be used to fuzz parts of SerenityOS's code base. This requires buildling with `clang`, so it's convenient to use a different build directory for that. Run CMake like this:
