spack.build_systems.aspell_dict module

class spack.build_systems.aspell_dict.AspellBuilder(pkg: PackageBase)

Bases: AutotoolsBuilder

The Aspell builder is close enough to an autotools builder to allow specializing the builder class, so to use variables that are specific to the Aspell extensions.

configure(pkg, spec, prefix)

Run “configure”, with the arguments specified by the builder and an appropriately set prefix.

spack.build_systems.autotools module

class spack.build_systems.autotools.AutotoolsBuilder(pkg: PackageBase)

Bases: BuilderWithDefaults

The autotools builder encodes the default way of installing software built with autotools. It has four phases that can be overridden, if need be:

1. autoreconf()

2. configure()

3. build()

4. install()

They all have sensible defaults and for many packages the only thing necessary is to override the helper method configure_args().

For a finer tuning you may also override:

Method	Purpose
build_targets	Specify make targets for the build phase
install_targets	Specify make targets for the install phase
check()	Run build time tests if required

property archive_files: List[str]

Files to archive for packages based on autotools

autoreconf(pkg: PackageBase, spec: Spec, prefix: Prefix) → None

Not needed usually, configure should be already there

autoreconf_extra_args: List[str] = []

Options to be passed to autoreconf when using the default implementation

property autoreconf_search_path_args: List[str]

Search path includes for autoreconf. Add an -I flag for all aclocal dirs of build deps, skips the default path of automake, move external include flags to the back, since they might pull in unrelated m4 files shadowing spack dependencies.

build(pkg: PackageBase, spec: Spec, prefix: Prefix) → None

Run “make” on the build targets specified by the builder.

property build_directory: str

Override to provide another place to build the package

build_system: str | None = 'autotools'

Build system name. Must also be defined in derived classes.

build_targets: List[str] = []

Targets for make during the build() phase

build_time_test_callbacks: List[str] = ['check']

Callback names for build-time test

check() → None

Run “make” on the test and check targets, if found.

configure(pkg: PackageBase, spec: Spec, prefix: Prefix) → None

Run “configure”, with the arguments specified by the builder and an appropriately set prefix.

property configure_abs_path: str

configure_args() → List[str]

Return the list of all the arguments that must be passed to configure, except --prefix which will be pre-pended to the list.

property configure_directory: str

Return the directory where ‘configure’ resides.

delete_configure_to_force_update() → None

enable_or_disable(name: str, activation_value: Callable | str | None = None, variant: str | None = None) → List[str]

Same as with_or_without() but substitute with with enable and without with disable.

Parameters:

• name – name of a valid multi-valued variant

• activation_value –

  if present accepts a single value and returns the parameter to be used leading to an entry of the type --enable-{name}={parameter}

  The special value “prefix” can also be assigned and will return spec[name].prefix as activation parameter.

Returns:

list of arguments to configure

force_autoreconf = False

Set to true to force the autoreconf step even if configure is present

install(pkg: PackageBase, spec: Spec, prefix: Prefix) → None

Run “make” on the install targets specified by the builder.

install_libtool_archives = False

If False deletes all the .la files in the prefix folder after the installation. If True instead it installs them.

install_targets = ['install']

Targets for make during the install() phase

install_time_test_callbacks: List[str] = ['installcheck']

Callback names for install-time test

installcheck() → None

Run “make” on the installcheck target, if found.

legacy_methods: Tuple[str, ...] = ('configure_args', 'check', 'installcheck')

Names associated with package methods in the old build-system format

property patch_config_files: bool

Whether to update old config.guess and config.sub files distributed with the tarball.

This currently only applies to ppc64le:, aarch64:, and riscv64 target architectures.

The substitutes are taken from the gnuconfig package, which is automatically added as a build dependency for these architectures. In case system versions of these config files are required, the gnuconfig package can be marked external, with a prefix pointing to the directory containing the system config.guess and config.sub files.

patch_libtool = True

Whether to update libtool (e.g. for Arm/Clang/Fujitsu/NVHPC compilers)

phases: Tuple[str, ...] = ('autoreconf', 'configure', 'build', 'install')

Phases of a GNU Autotools package

remove_libtool_archives() → None

Remove all .la files in prefix sub-folders if the package sets install_libtool_archives to be False.

run_after_callbacks = [(('autoreconf', None), <function AutotoolsBuilder._do_patch_config_files>), (('configure', None), <function AutotoolsBuilder._do_patch_libtool>), (('autoreconf', None), <function AutotoolsBuilder.set_configure_or_die>), (('build', None), <function execute_build_time_tests>), (('install', None), <function execute_install_time_tests>), (('install', None), <function AutotoolsBuilder.remove_libtool_archives>), (('install', 'platform=darwin'), <function apply_macos_rpath_fixups>), (('install', None), <function sanity_check_prefix>)]

set_configure_or_die() → None

Ensure the presence of a “configure” script, or raise. If the “configure” is found, a module level attribute is set.

Raises:

RuntimeError – if the “configure” script is not found

setup_build_environment(env)

Sets up the build environment for a package.

This method will be called before the current package prefix exists in Spack’s store.

Parameters:

env – environment modifications to be applied when the package is built. Package authors can call methods on it to alter the build environment.

with_or_without(name: str, activation_value: Callable | str | None = None, variant: str | None = None) → List[str]

Inspects a variant and returns the arguments that activate or deactivate the selected feature(s) for the configure options.

This function works on all type of variants. For bool-valued variants it will return by default --with-{name} or --without-{name}. For other kinds of variants it will cycle over the allowed values and return either --with-{value} or --without-{value}.

If activation_value is given, then for each possible value of the variant, the option --with-{value}=activation_value(value) or --without-{value} will be added depending on whether or not variant=value is in the spec.

Parameters:

• name – name of a valid multi-valued variant

• activation_value –

  callable that accepts a single value and returns the parameter to be used leading to an entry of the type --with-{name}={parameter}.

  The special value “prefix” can also be assigned and will return spec[name].prefix as activation parameter.

Returns:

list of arguments to configure

When this package depends on Python and find_python_hints is set to True, pass the defines {Python3,Python,PYTHON}_EXECUTABLE explicitly, so that CMake locates the right Python in its builtin FindPython3, FindPython, and FindPythonInterp modules. Spack does CMake’s job because CMake’s modules by default only search for Python versions known at the time of release.

flags_to_build_system_args(flags)

Return a list of all command line arguments to pass the specified compiler flags to cmake. Note CMAKE does not have a cppflags option, so cppflags will be added to cflags, cxxflags, and fflags to mimic the behavior in other tools.

spack.build_systems.cmake.define(cmake_var: str, value: Any) → str

Return a CMake command line argument that defines a variable.

The resulting argument will convert boolean values to OFF/ON and lists/tuples to CMake semicolon-separated string lists. All other values will be interpreted as strings.

Examples

[define("BUILD_SHARED_LIBS", True),
    define("CMAKE_CXX_STANDARD", 14),
    define("swr", ["avx", "avx2"])]

will generate the following configuration options:

["-DBUILD_SHARED_LIBS:BOOL=ON",
    "-DCMAKE_CXX_STANDARD:STRING=14",
    "-DSWR:STRING=avx;avx2]

spack.build_systems.cmake.define_cuda_architectures(pkg: PackageBase) → str

Returns the str -DCMAKE_CUDA_ARCHITECTURES:STRING=(expanded cuda_arch).

cuda_arch is variant composed of a list of target CUDA architectures and it is declared in the cuda package.

This method is no-op for cmake<3.18 and when cuda_arch variant is not set.

spack.build_systems.cmake.define_from_variant(pkg: PackageBase, cmake_var: str, variant: str | None = None) → str

Return a CMake command line argument from the given variant’s value.

The optional variant argument defaults to the lower-case transform of cmake_var.

Examples

Given a package with:

variant("cxxstd", default="11", values=("11", "14"),
        multi=False, description="")
variant("shared", default=True, description="")
variant("swr", values=any_combination_of("avx", "avx2"),
        description="")

calling this function like:

[
    self.define_from_variant("BUILD_SHARED_LIBS", "shared"),
    self.define_from_variant("CMAKE_CXX_STANDARD", "cxxstd"),
    self.define_from_variant("SWR"),
]

will generate the following configuration options:

[
    "-DBUILD_SHARED_LIBS:BOOL=ON",
    "-DCMAKE_CXX_STANDARD:STRING=14",
    "-DSWR:STRING=avx;avx2",
]

for <spec-name> cxxstd=14 +shared swr=avx,avx2

Note: if the provided variant is conditional, and the condition is not met, this function

returns an empty string. CMake discards empty strings provided on the command line.

spack.build_systems.cmake.define_hip_architectures(pkg: PackageBase) → str

Returns the str -DCMAKE_HIP_ARCHITECTURES:STRING=(expanded amdgpu_target).

amdgpu_target is variant composed of a list of the target HIP architectures and it is declared in the rocm package.

This method is no-op for cmake<3.18 and when amdgpu_target variant is not set.

spack.build_systems.cmake.generator(*names: str, default: str | None = None) → None

The build system generator to use.

See cmake --help for a list of valid generators. Currently, “Unix Makefiles” and “Ninja” are the only generators that Spack supports. Defaults to “Unix Makefiles”.

See https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html for more information.

Parameters:

• names – allowed generators for this package

spack.build_systems.intel module

class spack.build_systems.intel.IntelPackage(spec)

Bases: Package

Specialized class for licensed Intel software.

This class provides two phases that can be overridden:

1. configure()

2. install()

They both have sensible defaults and for many packages the only thing necessary will be to override setup_run_environment to set the appropriate environment variables.

auto_dispatch_options = ('COMMON-AVX512', 'MIC-AVX512', 'CORE-AVX512', 'CORE-AVX2', 'CORE-AVX-I', 'AVX', 'SSE4.2', 'SSE4.1', 'SSSE3', 'SSE3', 'SSE2')

filter_compiler_wrappers()

property global_license_file

Returns the path where a Spack-global license file should be stored.

All Intel software shares the same license, so we store it in a common ‘intel’ directory.

property headers

install(spec, prefix)

Runs Intel’s install.sh installation script. Afterwards, save the installer config and logs to <prefix>/.spack

property intel64_int_suffix

Provide the suffix for Intel library names to match a client application’s desired int size, conveyed by the active spec variant. The possible suffixes and their meanings are:

ilp64 all of int, long, and pointer are 64 bit, `` lp64`` only long and pointer are 64 bit; int will be 32bit.

languages: Dict[Spec, Set[str]]

property lapack_libs

modify_LLVMgold_rpath()

Add libimf.so and other required libraries to the RUNPATH of LLVMgold.so.

These are needed explicitly at dependent link time when ld -plugin LLVMgold.so is called by the compiler.

property mpi_compiler_wrappers

Return paths to compiler wrappers as a dict of env-like names

mpi_setup_dependent_build_environment(env, dependent_spec, compilers_of_client={})

Unified back-end for setup_dependent_build_environment() of Intel packages that provide ‘mpi’.

Parameters:

• env – same as in setup_dependent_build_environment().

• dependent_spec – same as in setup_dependent_build_environment().

• compilers_of_client (dict) – Conveys spack_cc, spack_cxx, etc., from the scope of dependent packages; constructed in caller.

normalize_path(component_path, component_suite_dir=None, relative=False)

Returns the absolute or relative path to a component or file under a component suite directory.

Intel’s product names, scope, and directory layout changed over the years. This function provides a unified interface to their directory names.

Parameters:

• component_path (str) – a component name like ‘mkl’, or ‘mpi’, or a deeper relative path.

• component_suite_dir (str) –

  _Unversioned_ name of the expected parent directory of component_path. When absent or None, an appropriate default will be used. A present but empty string “” requests that component_path refer to self.prefix directly.

  Typical values: compilers_and_libraries, composer_xe, parallel_studio_xe.

  Also supported: advisor, inspector, vtune. The actual directory name for these suites varies by release year. The name will be corrected as needed for use in the return value.

• relative (bool) – When True, return path relative to self.prefix, otherwise, return an absolute path (the default).

normalize_suite_dir(suite_dir_name, version_globs=['*.*.*'])

Returns the version-specific and absolute path to the directory of an Intel product or a suite of product components.

Parameters:

• suite_dir_name (str) –

  Name of the product directory, without numeric version.

  • Examples:

    composer_xe, parallel_studio_xe, compilers_and_libraries
    

  The following will work as well, even though they are not directly targets for Spack installation:

  advisor_xe, inspector_xe, vtune_amplifier_xe,
  performance_snapshots (new name for vtune as of 2018)
  

  These are single-component products without subordinate components and are normally made available to users by a toplevel psxevars.sh or equivalent file to source (and thus by the modulefiles that Spack produces).

• version_globs (list) – Suffix glob patterns (most specific first) expected to qualify suite_dir_name to its fully version-specific install directory (as opposed to a compatibility directory or symlink).

property scalapack_libs

setup_dependent_build_environment(env, dependent_spec)

setup_dependent_package(module, dep_spec)

Set up module-scope global variables for dependent packages.

This function is called when setting up the build and run environments of a DAG.

Examples:

1. Extensions often need to invoke the python interpreter from the Python installation being extended. This routine can put a python Executable as a global in the module scope for the extension package to simplify extension installs.

2. MPI compilers could set some variables in the dependent’s scope that point to mpicc, mpicxx, etc., allowing them to be called by common name regardless of which MPI is used.

Parameters:

• module – The Python module object of the dependent package. Packages can use this to set module-scope variables for the dependent to use.

• dependent_spec – The spec of the dependent package about to be built. This allows the extendee (self) to query the dependent’s state. Note that this package’s spec is available as self.spec.

setup_run_environment(env)

Adds environment variables to the generated module file.

These environment variables come from running:

$ source parallel_studio_xe_2017/bin/psxevars.sh intel64
[and likewise for MKL, MPI, and other components]

spack.build_systems.msbuild module

class spack.build_systems.msbuild.MSBuildBuilder(pkg: PackageBase)

Bases: BuilderWithDefaults

The MSBuild builder encodes the most common way of building software with Mircosoft’s MSBuild tool. It has two phases that can be overridden, if need be:

1. build()

2. install()

It is usually necessary to override the install() phase as many packages with MSBuild systems neglect to provide an install target. The default install phase will attempt to invoke an install target from MSBuild. If none exists, this will result in a build failure

For a finer tuning you may override:

Method	Purpose

spack.build_systems.nmake module

class spack.build_systems.nmake.NMakeBuilder(pkg: PackageBase)

Bases: BuilderWithDefaults

The NMake builder encodes the most common way of building software with Mircosoft’s NMake tool. It has two phases that can be overridden, if need be:

1. build()

2. install()

It is usually necessary to override the install() phase as many packages with NMake systems neglect to provide an install target. The default install phase will attempt to invoke an install target from NMake. If none exists, this will result in a build failure

For a finer tuning you may override:

Method	Purpose
build_targets	Specify nmake targets for the build phase
install_targets	Specify nmake targets for the install phase
build_directory()	Directory where the project makefile is located

build(pkg, spec, prefix)

Run “nmake” on the build targets specified by the builder.

property build_directory

Return the directory containing the makefile.

build_system: str | None = 'nmake'

Build system name. Must also be defined in derived classes.

build_targets: List[str] = []

Targets for make during the build() phase

define(nmake_arg, value)

Helper method to format arguments to nmake command line

property ignore_quotes

Control whether or not Spack warns about quoted arguments passed to build utilities. If this is True, spack will not warn about quotes. This is useful in cases with a space in the path or when build scripts require quoted arugments.

install(pkg, spec, prefix)

Run “nmake” on the install targets specified by the builder. This is INSTALL by default

install_targets: List[str] = ['INSTALL']

Targets for make during the install() phase

property makefile_name

Name of the current makefile. This is currently an empty value. If a project defines this value, it will be used with the /f argument to provide nmake an explicit makefile. This is usefule in scenarios where there are multiple nmake files in the same directory.

property makefile_root

The relative path to the directory containing nmake makefile

This path is relative to the root of the extracted tarball, not to the build_directory. Defaults to the current directory.

nmake_args()

Define build arguments to NMake. This is an empty list by default. Individual packages should override to specify NMake args to command line

nmake_install_args()

Define arguments appropriate only for install phase to NMake. This is an empty list by default. Individual packages should override to specify NMake args to command line

override_env(var_name, new_value)

spack.build_systems.perl module

class spack.build_systems.perl.PerlBuilder(pkg: PackageBase)

Bases: BuilderWithDefaults

1. configure()

2. build()

3. check()

4. install()

The default methods use, in order of preference:

Bases: PackageBase

add_files_to_view(view, merge_map, skip_if_exists=True)

Given a map of package files to destination paths in the view, add the files to the view. By default this adds all files. Alternative implementations may skip some files, for example if other packages linked into the view already include the file.

Parameters:

• view (spack.filesystem_view.FilesystemView) – the view that’s updated

• merge_map (dict) – maps absolute source paths to absolute dest paths for all files in from this package.

• skip_if_exists (bool) – when True, don’t link files in view when they already exist. When False, always link files, without checking if they already exist.
