Mostly everything needed to produce distribution packages for OpenMeters is contained within this directory.

Arch users are served by the AUR (openmeters-git), so .pkg.tar.zst is not built here.

• cargo (to produce the release binary, invoked separately)
• nfpm
• git, rustc, objdump, tar, xz, sha256sum, awk

• Makefile - driver.
• nfpm.yaml - deb/rpm spec.
• copyright - Debian copyright/license metadata, also shipped in tarballs.

Build the release binary first from the repo root. The Makefile only assembles artifacts.

cargo build --locked --release # from repo root
cd packaging

make check        # print the package ABI/dependency floor
make MAX_GLIBC_VERSION=2.39 check
make tarball      # dist/openmeters-<version>-x86_64-linux-gnu.tar.xz
make deb          # dist/openmeters_<version>-1_amd64.deb
make rpm          # dist/openmeters-<version>-1.x86_64.rpm
make RELEASE=2 all # package rebuild: deb/rpm release number 2
make all          # all of the above, plus SHA256SUMS
make clean        # wipe dist/

Version is parsed from the root Cargo.toml. RELEASE defaults to 1 and is passed to nFPM for Debian/RPM package rebuilds. Run nFPM through make. MAX_GLIBC_VERSION is optional for local builds, but CI sets it so official artifacts cannot silently move to a newer glibc floor.

dist/
  openmeters-<version>-x86_64-linux-gnu/      staging tree for the tarball
  openmeters-<version>-x86_64-linux-gnu.tar.xz
  openmeters_<version>-<release>_amd64.deb
  openmeters-<version>-<release>.x86_64.rpm
  SHA256SUMS

dist/ is gitignored.

• glibc >= 2.39 for pre-built release artifacts. Local packages declare the highest GLIBC_* symbol required by the built binary.
• libgcc_s.so.1
• libpipewire-0.3.so.0 >= 0.3.77 (audio capture and graph integration)
• libvulkan.so.1 (wgpu uses the distro's Vulkan loader + ICDs)
• Wayland: libwayland-client.so.0
• X11: libX11.so.6, libX11-xcb.so.1, libxcb.so.1, libXcursor.so.1, libXi.so.6
• Keyboard input: libxkbcommon.so.0, libxkbcommon-x11.so.0

Some graphics/windowing libraries are loaded with dlopen, so they may not appear in readelf -d output.
