Overview
A packaging approach that bundles pre-compiled C extensions and dependencies into platform-specific wheel files for zero-compilation installation.
Description
Binary wheels are pre-compiled Python packages that include the compiled C extension (talib/_ta_lib.so or .pyd) and bundle the TA-Lib C shared library. This eliminates the need for users to install the C library separately or have a C compiler.
The TA-Lib Python project builds wheels for 7 platform/architecture combinations using cibuildwheel in CI:
- Linux x86_64 and arm64
- macOS x86_64 and arm64 (Apple Silicon)
- Windows amd64, x86, and arm64
Wheel availability depends on Python version (3.9-3.14) and platform.
Usage
Attempt binary wheel installation first (pip install TA-Lib). If a wheel is available for your platform and Python version, installation completes without a C compiler or TA-Lib C library.
Theoretical Basis
Binary wheel installation follows a platform matching algorithm:
# Abstract wheel selection
# pip matches wheel filename against system:
# TA_Lib-0.6.9-cp312-cp312-manylinux_x86_64.whl
# Components: package-version-python-abi-platform.whl
if wheel_exists(python_version, platform, architecture):
install_wheel() # No compilation needed
else:
fall_back_to_source_build() # Requires C library + compiler
