`nimble setup -l` (used by status-go's from-source builds: the functional-test Docker image with nim 2.2.4 and the Windows job) walked each locked package's `dependencies` array, looked every name up in the lock's package table, and crashed with "key not found: nim" because the `nim` package entry was removed to keep the offline Nix build working. Strip the implicit `nim` compiler from the dependency arrays instead of re-adding it as a package: re-adding it makes `nimble setup -l` clone and rebuild the Nim compiler from source (slow, pointless — the toolchain is already installed) and its checksum is nimble-version-specific. With no `nim` references, `setup -l` resolves cleanly against the system compiler, and the Nix build (which never choked on the missing key) is unaffected.

nim-sds
Nim implementation of the e2e reliability protocol.
Prerequisites
- Nix package manager
Quick start
git clone https://github.com/logos-messaging/nim-sds.git
cd nim-sds
# Build the shared library
nix build '.#libsds'
# Run tests
nix develop --command nimble test
Building
Desktop
nix build --print-out-paths '.#libsds'
Android
nix build --print-out-paths '.#libsds-android-arm64'
nix build --print-out-paths '.#libsds-android-amd64'
nix build --print-out-paths '.#libsds-android-x86'
nix build --print-out-paths '.#libsds-android-arm'
iOS
nix build --print-out-paths '.#libsds-ios'
Development shell
Enter the dev shell:
nix develop
Build using nimble tasks:
# Dynamic library (auto-detects OS)
nimble libsdsDynamicMac # macOS
nimble libsdsDynamicLinux # Linux
nimble libsdsDynamicWindows # Windows
# Static library
nimble libsdsStaticMac # macOS
nimble libsdsStaticLinux # Linux
nimble libsdsStaticWindows # Windows
Run tests:
nimble test
The built library is output to build/.
Android (without Nix)
Download the latest Android NDK:
cd ~
wget https://dl.google.com/android/repository/android-ndk-r27c-linux.zip
unzip android-ndk-r27c-linux.zip
Add to ~/.bashrc:
export ANDROID_NDK_ROOT=$HOME/android-ndk-r27c
export PATH=$ANDROID_NDK_ROOT/toolchains/llvm/prebuilt/linux-x86_64/bin:$PATH
Then build:
ARCH=arm64 nimble libsdsAndroid
| Architecture | Command |
|---|---|
| arm64 | ARCH=arm64 nimble libsdsAndroid |
| amd64 | ARCH=amd64 nimble libsdsAndroid |
| x86 | ARCH=x86 nimble libsdsAndroid |
The library is output to build/libsds.so.
Dependency management
Dependencies are managed by Nimble and pinned via nimble.lock.
To set up dependencies locally:
nimble setup -l
To update dependencies:
nimble lock
After updating nimble.lock, the Nix outputHash in nix/deps.nix must be recalculated
by running nix build and updating the hash from the error output.
