Both are declared by Logos modules in metadata nix.packages.runtime and neither builds for x86_64-w64-mingw32. Fixed here rather than in each consumer, since metadata has no per-platform gating (parseMetadata.nix produces one flat list). Common cause: nixpkgs builds mingw-w64 against mcfgthread, so pthread.h and libpthread.a are absent from the whole cross closure. This is the fifth unrelated-looking failure from that one hole -- libpq, Rust's windows-gnu std, lsquic's clock_gettime64, nim-boringssl, and now abseil -- and each time the fix is windows.pthreads in buildInputs. abseil-cpp: thread_identity.cc includes <pthread.h> unconditionally. libpq: four obstacles -- curlSupport=false (postgres 18 links libcurl for OAuth, and curl cross drags in ngtcp2 -> nghttp3, whose EXAMPLES include <arpa/inet.h>); drop make-shell-wrapper-hook (wants a HOST bash, which mingw does not build, and libpq never calls wrapProgram); windows.pthreads; separateDebugInfo=false (that hook is the ELF split). The libpq entry is the CLIENT library only. Full postgresql has no mingw build and is deliberately not exposed -- a module wanting postgres should declare libpq, which is all it ever links or dlopens. Verified: abseil-cpp builds producing libabsl_*.dll.a; libpq.dll builds, loads on real Windows 10.0.26200, and PQconnectdb/PQexec/PQfinish/ PQlibVersion resolve.

logos-nix
Shared Nix infrastructure for all Logos projects. Provides a single pinned nixpkgs and common build dependencies so downstream repos stay in sync without depending on an actual project as their flake root.
Previously, logos-cpp-sdk served as the follows root. This caused unnecessary cache invalidation on every SDK commit and coupled infrastructure concerns to an active development project.
What it provides
| Output | Description |
|---|---|
nixpkgs input |
Pinned nixos-unstable revision shared across all projects |
devShells.default |
Common dev environment: cmake, ninja, pkg-config, qt6.qtbase, qt6.qtremoteobjects |
lib.forAllSystems |
Helper to generate outputs for all supported systems |
lib.supportedSystems |
aarch64-darwin, x86_64-darwin, aarch64-linux, x86_64-linux |
Usage
As a follows root (most projects)
{
inputs = {
logos-nix.url = "github:logos-co/logos-nix";
nixpkgs.follows = "logos-nix/nixpkgs";
};
}
Using the dev shell
{
inputs = {
logos-nix.url = "github:logos-co/logos-nix";
nixpkgs.follows = "logos-nix/nixpkgs";
};
outputs = { self, nixpkgs, logos-nix }:
logos-nix.lib.forAllSystems ({ system, pkgs }: {
devShells.default = pkgs.mkShell {
inputsFrom = [ logos-nix.devShells.${system}.default ];
# add project-specific deps here
};
});
}
Migration from logos-cpp-sdk
inputs = {
- logos-cpp-sdk.url = "github:logos-co/logos-cpp-sdk";
- nixpkgs.follows = "logos-cpp-sdk/nixpkgs";
+ logos-nix.url = "github:logos-co/logos-nix";
+ nixpkgs.follows = "logos-nix/nixpkgs";
+ logos-cpp-sdk.url = "github:logos-co/logos-cpp-sdk"; # only if you need the SDK
};
Then run nix flake update to re-lock.
