Bases:
OperatingSystem
- class spack.operating_systems.LinuxDistro[source]
Bases:
OperatingSystem
This class will represent the autodetected operating system for a Linux System. Since there are many different flavors of Linux, this class will attempt to encompass them all through autodetection using the python module platform and the method platform.dist()
- class spack.operating_systems.MacOs[source]
Bases:
OperatingSystem
This class represents the macOS operating system. This will be auto detected using the python platform.mac_ver. The macOS platform will be represented using the major version operating system name, i.e el capitan, yosemite…etc.
- class spack.operating_systems.OperatingSystem(name, version)[source]
Bases:
object
Base class for all the Operating Systems.
On a multiple architecture machine, the architecture spec field can be set to build a package against any target and operating system that is present on the platform. On Cray platforms or any other architecture that has different front and back end environments, the operating system will determine the method of compiler detection.
There are two different types of compiler detection:
Through the $PATH env variable (front-end detection)
Through the module system. (back-end detection)
Depending on which operating system is specified, the compiler will be detected using one of those methods.
For platforms such as linux and darwin, the operating system is autodetected.
- class spack.operating_systems.WindowsOs[source]
Bases:
OperatingSystem
This class represents the Windows operating system. This will be auto detected using the python platform.win32_ver() once we have a python setup that runs natively. The Windows platform will be represented using the major version operating system number, e.g. 10.

- spack.operating_systems.mac_os.macos_cltools_version()[source]
Find the last installed version of the CommandLineTools.
The CLT version might only affect the build if it’s selected as the macOS SDK path.
- spack.operating_systems.mac_os.macos_sdk_version()[source]
Return the version of the active macOS SDK.
The SDK version usually corresponds to the installed Xcode version and can affect how some packages (especially those that use the GUI) can fail. This information should somehow be embedded into the future “compilers are dependencies” feature.
The macOS deployment target cannot be greater than the SDK version, but usually it can be at least a few versions less.
- spack.operating_systems.mac_os.macos_version()[source]
Get the current macOS version as a version object.
This has three mechanisms for determining the macOS version, which is used for spack identification (the
os
in the spec’sarch
) and indirectly for setting the value ofMACOSX_DEPLOYMENT_TARGET
, which affects theminos
value of theLC_BUILD_VERSION
macho header. Mixingminos
values can lead to lots of linker warnings, and using a consistent version (pinned to the major OS version) allows distribution across clients that might be slightly behind.The version determination is made with three mechanisms in decreasing priority:
The
MACOSX_DEPLOYMENT_TARGET
variable overrides the actual operating system version, just like the value can be used to build for older macOS targets on newer systems. Spack currently will truncate this value when building packages, but at least the major version will be the same.The system
sw_vers
command reports the actual operating system version.The Python
platform.mac_ver
function is a fallback if the operating system identification fails, because some Python versions and/or installations report the OS on which Python was built rather than the one on which it is running.
