classmethod default_version(comp)

The --version option works for clang compilers. On most platforms, output looks like this:

clang version 3.1 (trunk 149096)
Target: x86_64-unknown-linux-gnu
Thread model: posix

On macOS, it looks like this:

Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin15.2.0
Thread model: posix
classmethod extract_version_from_output(output)

Extracts the version from compiler’s output.

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.

Module contents

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: spack.error.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

compiler_name

Alias for field number 1

os

Alias for field number 0

version

Alias for field number 2

exception spack.compilers.CompilerSpecInsufficientlySpecificError(compiler_spec)

Bases: spack.error.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

id

Alias for field number 0

language

Alias for field number 2

path

Alias for field number 3

variation

Alias for field number 1

exception spack.compilers.InvalidCompilerConfigurationError(compiler_spec)

Bases: spack.error.SpackError

class spack.compilers.NameVariation(prefix, suffix)

Bases: tuple

Variations on a matched compiler name

prefix

Alias for field number 0

suffix

Alias for field number 1

exception spack.compilers.NoCompilerForSpecError(compiler_spec, target)

Bases: spack.error.SpackError

exception spack.compilers.NoCompilersError

Bases: spack.error.SpackError

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)
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 (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.compilers_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)

Returns 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

Returns

List of compilers found

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.get_compiler_duplicates(cspec_like, *args, **kwargs)
spack.compilers.get_compilers(config, cspec=None, arch_spec=None)
spack.compilers.is_mixed_toolchain(compiler)

Returns True if the current compiler is a mixed toolchain, False otherwise.

Parameters

compiler (Compiler) – a valid compiler object

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

spack.compilers.pkg_spec_for_compiler(cspec)

Return the spec of the package that provides the compiler.

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

Return a set of names of compilers supported by Spack.

See available_compilers() to get a list of all the available versions of supported compilers.
