# Cross instructions

## Set up the toolchain
```
$ crossdev riscv64-unknown-linux-gnu
```

# Avoid dependency hell and populate the `ROOT`
Emerge `sys-libs/glibc` (no, `@system` / `@world` won't make it realise it can/should do this, don't ask why, I don't know):

```
$ riscv64-unknown-linux-gnu-emerge -v1 sys-libs/glibc
$ riscv64-unknown-linux-gnu-emerge -v1 @system
```

# Profile setup


## Choosing profile
Run: `PORTAGE_CONFIGROOT=/usr/riscv64-unknown-linux-gnu eselect profile list`

Pick a nice looking one, like `default/linux/riscv/20.0/rv64gc/lp64`.

```
$ PORTAGE_CONFIGROOT=/usr/riscv64-unknown-linux-gnu eselect profile set default/linux/riscv/20.0/rv64gc/lp64
```

## Remove -pam nonsense

Edit `/usr/riscv64-unknown-linux-gnu/etc/portage/make.conf` to remove `USE=-pam` because it'll conflict with `sys-apps/util-linux` being the default `su` provider:

```
$ sed -i -e "s:-pam::" /usr/riscv64-unknown-linux-gnu/etc/portage/make.conf
```

## Avoid circular deps

```
$ USE="-filecaps" riscv64-unknown-linux-gnu-emerge -v1 @system
```
