class macOSPythonBuilder : NixPythonBuilder {
|
|
<#
|
|
.SYNOPSIS
|
|
MacOS Python builder class.
|
|
|
|
.DESCRIPTION
|
|
Contains methods that required to build macOS Python artifact from sources. Inherited from base NixPythonBuilder.
|
|
|
|
While python.org provides precompiled binaries for macOS, switching to them risks breaking existing customers.
|
|
If we wanted to start using the official binaries instead of building from source, we should avoid changing previous versions
|
|
so we remain backwards compatible.
|
|
|
|
.PARAMETER platform
|
|
The full name of platform for which Python should be built.
|
|
|
|
.PARAMETER version
|
|
The version of Python that should be built.

### For Python versions which support it, compile a universal2 (arm64 + x86_64 hybrid) build. The arm64 slice
|
|
### will never be used itself by a Github Actions runner but using a universal2 Python is the only way to build
|
|
### universal2 C extensions and wheels. This is supported by Python >= 3.10 and was backported to Python >=
|
|
### 3.9.1 and >= 3.8.10.

### OS X 10.11, Apple no longer provides header files for the deprecated system version of OpenSSL.
|
|
### Solution is to install these libraries from a third-party package manager,
|
|
### and then add the appropriate paths for the header and library files to configure command.
