spack.compilers package

This module contains functions related to finding compilers on the system and configuring Spack to use multiple compilers.

class spack.compilers.CacheReference(val)

Bases: object

This acts as a hashable reference to any object (regardless of whether the object itself is hashable) and also prevents the object from being garbage-collected (so if two CacheReference objects are equal, they will refer to the same object, since it will not have been gc’ed since the creation of the first CacheReference).

exception spack.compilers.CompilerDuplicateError(compiler_spec, arch_spec)

Bases: SpackError

class spack.compilers.CompilerID(os, compiler_name, version)

Bases: tuple

Gathers the attribute values by which a detected compiler is considered unique in Spack.

• os: the operating system

• compiler_name: the name of the compiler (e.g. ‘gcc’, ‘clang’, etc.)

• version: the version of the compiler

property compiler_name

Alias for field number 1

property os

Alias for field number 0

property version

Alias for field number 2

exception spack.compilers.CompilerSpecInsufficientlySpecificError(compiler_spec)

Bases: SpackError

class spack.compilers.DetectVersionArgs(id, variation, language, path)

Bases: tuple

Groups together the arguments needed by detect_version. The four entries in the tuple are:

• id: An instance of the CompilerID named tuple (version can be set to None

  as it will be detected later)

• variation: a NameVariation for file being tested

• language: compiler language being tested (one of ‘cc’, ‘cxx’, ‘fc’, ‘f77’)

• path: full path to the executable being tested

property id

Alias for field number 0

property language

Alias for field number 2

property path

Alias for field number 3

property variation

Alias for field number 1

exception spack.compilers.InvalidCompilerConfigurationError(compiler_spec)

Bases: SpackError

class spack.compilers.NameVariation(prefix, suffix)

Bases: tuple

Variations on a matched compiler name

property prefix

Alias for field number 0

property suffix

Alias for field number 1

exception spack.compilers.NoCompilerForSpecError(compiler_spec, target)

Bases: SpackError

exception spack.compilers.NoCompilersError

Bases: SpackError

exception spack.compilers.UnknownCompilerError(compiler_name)

spack.compilers.add_compilers_to_config(compilers, scope=None, init_config=True)

Add compilers to the config for the specified architecture.

Parameters

• compilers – a list of Compiler objects.

• scope – configuration scope to modify.

spack.compilers.all_compiler_specs(scope=None, init_config=True)

spack.compilers.all_compiler_types()

spack.compilers.all_compilers(scope=None, init_config=True)

spack.compilers.all_compilers_config(scope=None, init_config=True)

Return a set of specs for all the compiler versions currently available to build with. These are instances of CompilerSpec.

spack.compilers.all_os_classes()

Return the list of classes for all operating systems available on this platform

spack.compilers.arguments_to_detect_version_fn(operating_system, paths)

Returns a list of DetectVersionArgs tuples to be used in a corresponding function to detect compiler versions.

The operating_system instance can customize the behavior of this function by providing a method called with the same name.

Parameters

• operating_system (spack.operating_systems.OperatingSystem) – the operating system on which we are looking for compilers

• paths – paths to search for compilers

Returns

List of DetectVersionArgs tuples. Each item in the list will be later mapped to the corresponding function call to detect the version of the compilers in this OS.

spack.compilers.class_for_compiler_name(compiler_name)

Given a compiler module name, get the corresponding Compiler class.

spack.compilers.compiler_config_files()

spack.compilers.compiler_for_spec(cspec_like, *args, **kwargs)

spack.compilers.compiler_from_dict(items)

spack.compilers.compiler_specs_for_arch(arch_spec, scope=None)

spack.compilers.compilers_for_spec(cspec_like, *args, **kwargs)

spack.compilers.detect_version(detect_version_args)

Computes the version of a compiler and adds it to the information passed as input.

As this function is meant to be executed by worker processes it won’t raise any exception but instead will return a (value, error) tuple that needs to be checked by the code dispatching the calls.

Parameters

detect_version_args (DetectVersionArgs) – information on the compiler for which we should detect the version.

Returns

A (DetectVersionArgs, error) tuple. If error is None the version of the compiler was computed correctly and the first argument of the tuple will contain it. Otherwise error is a string containing an explanation on why the version couldn’t be computed.

spack.compilers.find(cspec_like, *args, **kwargs)

spack.compilers.find_compilers(path_hints=None)

Return the list of compilers found in the paths given as arguments.

Parameters

path_hints (list or None) – list of path hints where to look for. A sensible default based on the PATH environment variable will be used if the value is None

spack.compilers.find_new_compilers(path_hints=None, scope=None)

Same as find_compilers but return only the compilers that are not already in compilers.yaml.

Parameters

• path_hints (list or None) – list of path hints where to look for. A sensible default based on the PATH environment variable will be used if the value is None

• scope (str) – scope to look for a compiler. If None consider the merged configuration.

spack.compilers.find_specs_by_arch(cspec_like, *args, **kwargs)

spack.compilers.get_compiler_config(scope=None, init_config=True)

Return the compiler configuration for the specified architecture.

spack.compilers.make_compiler_list(detected_versions)

Process a list of detected versions and turn them into a list of compiler specs.

Parameters

detected_versions (list) – list of DetectVersionArgs containing a valid version

Returns

list of Compiler objects

Return type

list

Return the spec of the package that provides the compiler.

spack.compilers.remove_compiler_from_config(cspec_like, *args, **kwargs)

Given a list of compilers, remove those that are already defined in the configuration.

spack.compilers.supported(cspec_like, *args, **kwargs)

spack.compilers.supported_compilers()

Return a set of names of compilers supported by Spack.

openmp_flag = '-Xpreprocessor -fopenmp'

setup_custom_environment(pkg, env)

Set the DEVELOPER_DIR environment for the Xcode toolchain.

On macOS, not all buildsystems support querying CC and CXX for the compilers to use and instead query the Xcode toolchain for what compiler to run. This side-steps the spack wrappers. In order to inject spack into this setup, we need to copy (a subset of) Xcode.app and replace the compiler executables with symlinks to the spack wrapper. Currently, the stage is used to store the Xcode.app copies. We then set the ‘DEVELOPER_DIR’ environment variables to cause the xcrun and related tools to use this Xcode.app.

class spack.compilers.dpcpp.Dpcpp(cspec, operating_system, target, paths, modules=None, alias=None, environment=None, extra_rpaths=None, enable_implicit_rpaths=None, **kwargs)

Bases: Oneapi

This is the same as the oneAPI compiler but uses dpcpp instead of icpx (for DPC++ source files). It explicitly refers to dpcpp, so that CMake test files which check the compiler name (e.g. CMAKE_CXX_COMPILER) detect it as dpcpp.

Ideally we could switch out icpx for dpcpp where needed in the oneAPI compiler definition, but two things are needed for that: (a) a way to tell the compiler that it should be using dpcpp and (b) a way to customize the link_paths
