spack.platforms package
- class spack.platforms.Darwin[source]
Bases:
Platform- binary_formats = ['macho']
binary formats used on this platform; used by relocation logic
- classmethod detect()[source]
Returns True if the host platform is detected to be the current Platform class, False otherwise.
Derived classes are responsible for implementing this method.
- setup_platform_environment(pkg, env)[source]
Specify deployment target based on target OS version.
The
MACOSX_DEPLOYMENT_TARGETenvironment variable provides a default-mmacosx-version-minargument for GCC and Clang compilers, as well as the default value ofCMAKE_OSX_DEPLOYMENT_TARGETfor CMake-based build systems. The default value for the deployment target is usually the major version (11, 10.16, …) for CMake and Clang, but some versions of GCC specify a minor component as well (11.3), leading to numerous link warnings about inconsistent or incompatible target versions. Setting the environment variable ensures consistent versions for an install toolchain target, even when the host macOS version changes.TODO: it may be necessary to add SYSTEM_VERSION_COMPAT for older versions of the macosx developer tools; see https://github.com/spack/spack/pull/26290 for discussion.

Platform
- class spack.platforms.Platform(name)[source]
Bases:
objectPlatform is an abstract class extended by subclasses.
Platform also contain a priority class attribute. A lower number signifies higher priority. These numbers are arbitrarily set and can be changed though often there isn’t much need unless a new platform is added and the user wants that to be detected first.
- binary_formats = ['elf']
binary formats used on this platform; used by relocation logic
- deprecated_names = ['frontend', 'fe', 'backend', 'be']
- classmethod detect()[source]
Returns True if the host platform is detected to be the current Platform class, False otherwise.

- class spack.platforms.Test(name=None)[source]
Bases:
Platform
- class spack.platforms.Windows[source]
Bases:
Platform
- spack.platforms.by_name(name)[source]
Return a platform object that corresponds to the given name or None if there is no match.
- Parameters:
name (str) – name of the platform
- spack.platforms.host()
The current platform used by Spack. May be swapped by the use_platform context manager.
- spack.platforms.reset()[source]
The result of the host search is memoized. In case it needs to be recomputed we must clear the cache, which is what this function does.
