README.md
Description
This folder contains configuration for Nix, a purely functional package manager used by the Status app for its build process.
Configuration
The main config file is nix/nix.conf
and its main purpose is defining the binary caches which allow download of packages to avoid having to compile them yourself locally.
NOTE: If you are in Asia you might want to add the https://nix-cache-cn.status.im/
to be first in order of substituters
. Removing cache.nixos.org
could also help.
Shell
In order to access an interactive Nix shell a user should run make shell
.
The Nix shell is started in this repo via the nix/shell.sh
script, which is a wrapper around the nix-shell
command and is intended for use with our main Makefile
. This allows for an implicit use of nix-shell
as the default shell in the Makefile
.
By default the shell starts without any specific target platform, if you want to change that you should export the TARGET_OS
env variable with the right value:
make shell TARGET_OS=android
This way your shell and all other nix commands should run in a setup that is tailored towards Android development.
For valid values you can check the nix/platform.nix
file.
Known Issues
MacOS 10.15 "Catalina"
There is an unsolved issue with the root(/
) file system in 10.15
being read-only:
https://github.com/NixOS/nix/issues/2925
Our current recommended workaround is putting /nix
under /opt/nix
and symlinking it via /etc/synthetic.conf
:
sudo mkdir /opt/nix
sudo chown ${USER} /opt/nix
sudo sh -c "echo 'nix\t/opt/nix' >> /etc/synthetic.conf"
reboot
After the system reboots you should see the /nix
symlink in place:
% ls -l /nix
lrwxr-xr-x 1 root wheel 8 Oct 11 13:53 /nix -> /opt/nix
In order to be able to use Nix with a symlinked /nix
you need to include this in your shell:
export NIX_IGNORE_SYMLINK_STORE=1
Add it to your .bashrc
or any other shell config file.
NOTE: Your old /nix
directory will end up in /Users/Shared/Relocated Items/Security/nix
after OS upgrade.
