Install a release without Cargo

Each tagged release publishes a source archive, native packages for Linux, macOS, and Windows, and a platform-neutral Python wheel. A native package contains the shared and static libraries, C and C++ headers, CMake and pkg-config metadata, the postproject CLI, licenses, and tested examples.

Download the archive for the target platform and its adjacent .sha256 file from the GitHub release. For example, on Linux:

sha256sum --check postproject-0.3.0-alpha.1-linux-x86_64.tar.gz.sha256
mkdir postproject-0.3.0-alpha.1
tar -xzf postproject-0.3.0-alpha.1-linux-x86_64.tar.gz \
  -C postproject-0.3.0-alpha.1
export PATH="$PWD/postproject-0.3.0-alpha.1/bin:$PATH"
export LD_LIBRARY_PATH="$PWD/postproject-0.3.0-alpha.1/lib${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}"
postproject --version

Use DYLD_LIBRARY_PATH for an unpacked macOS archive. The Windows ZIP places postproject.exe and postproject.dll together in bin; add that directory to PATH. Applications can instead copy the archive into a conventional prefix whose loader configuration already searches its lib directory.

CMake consumers point CMAKE_PREFIX_PATH at the extracted directory and link PostProject::postproject. pkg-config consumers add its lib/pkgconfig directory to PKG_CONFIG_PATH. Neither path invokes Cargo.

The wheel wraps the same native ABI and does not bundle a second copy of the library. Install it beside the native archive and give Python the absolute library path when opening or creating a production:

python -m pip install postproject-0.3.0a1-py3-none-any.whl

from postproject import Production

production = Production.open(
    "production.pproj",
    library_path="/opt/postproject/lib/libpostproject.so",
)

The Python snippet is the same public call exercised by the installed Python quickstart. The CLI uses the Rust implementation directly; it does not dynamically load the C library.
