Changes: - Adds a new `nix-gc` Makefile target for removing old packages - Moves all `nix/*.sh` files to `nix/scripts/*.sh` to make things more tidy - Renames `TARGET_OS` into `TARGET` and makes it effective only with `nix/scripts/shell.sh` - Renames `target-os` Nix argument to just `target` and makes it effective only with `shell.nix` - Drops `IN_CI_ENVIRONMENT` env variable which was useless - Drops use of `target-os` argument outside of `shell.nix` (with few exceptions, but just in naming) - `nix/platform.nix` has been made obsolete and removed - Moves the definition of all major targets to `nix/targets.nix` - Moves the definition of all major shells to `nix/shells.nix` - Makes `default.nix` and `shell.nix` just thin wrappers around `nix/default.nix` - `nix/nixpkgs-bootstrap.nix` has been moved to `nix/pkgs.nix` - All package and tool overrides have been moved to `nix/pkgs.nix` - Explicit passing of contents of `pkgs` has been removed in favor of `callPackage` doing it for us - `nix/bootstrapped-shell.nix` has been moved to `nix/tools/mkShell.nix` - A new `mergeSh` tool has been added to `pkgs` from `nix/tools/mergeSh.nix` - This tool is used to merge shells created using `mkShell` - `mobile/targets/jsbundle.nix` has been moved to `mobile/android/jsbundle/default.nix` - Moves `status-go` version sanitization to `nix/status-go/utils.nix` - Renames version to rawVersion and versionName to cleanVersion in status-go derivation - Ports nix/mobile/ios/install-pods-and-status-go.sh to Nix sub-shells - Moves adjustment of `inotify/max_user_watches` out into `scripts/inotify_fix.sh` - Makes iOS builds use the Nix version of Fastlane Signed-off-by: Jakub Sokołowski <jakub@status.im>

# Description
|
|
|
|
This folder contains configuration for [Nix](https://nixos.org/), a purely functional package manager used by the Status app for its build process.
|
|
|
|
## Configuration
|
|
|
|
The main config file is [`nix/nix.conf`](/nix/nix.conf) and its main purpose is defining the [binary caches](https://nixos.org/nix/manual/#ch-basic-package-mgmt) 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/scripts/shell.sh`](/nix/scripts/shell.sh) script, which is a wrapper around the `nix-shell` command and is intended for use with our main [`Makefile`](/Makefile). This allows for an implicit use of `nix-shell` as the default shell in the `Makefile`.
|
|
|
|
Normally the shell starts without any specific target platform, if you want to change that you should export the `TARGET` env variable with appropriate value:
|
|
|
|
```bash
|
|
make shell TARGET=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/shells.nix`](/nix/shells.nix) file.
|
|
|
|
## Using a local status-go repository
|
|
|
|
If you need to use a locally checked-out status-go repository as a dependency of status-react, you can achieve that by defining the `STATUS_GO_SRC_OVERRIDE`
|
|
environment variable.
|
|
|
|
```sh
|
|
export STATUS_GO_SRC_OVERRIDE=$GOPATH/src/github.com/status-im/status-go
|
|
# Any command that you run from now on
|
|
# will use the specified status-go location
|
|
make release-android
|
|
```
|
|
|
|
or for a one-off build:
|
|
|
|
```sh
|
|
make release-android STATUS_GO_SRC_OVERRIDE=$GOPATH/src/github.com/status-im/status-go
|
|
```
|

## 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`:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
% 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:
|
|
|
|
```bash
|
|
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.
