Submodules

spack.build_systems.autotools module

class spack.build_systems.autotools.AutotoolsPackage(spec)

Bases: spack.package.PackageBase

Specialized class for packages built using GNU Autotools.

This class provides four phases that can be overridden:

They all have sensible defaults and for many packages the only thing necessary will be 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
autoreconf(spec, prefix)

Not needed usually, configure should be already there

autoreconf_extra_args = []

Options to be passed to autoreconf when using the default implementation

build(spec, prefix)

Makes the build targets specified by :py:attr:~.AutotoolsPackage.build_targets

build_directory

Override to provide another place to build the package

build_system_class = 'AutotoolsPackage'

This attribute is used in UI queries that need to know the build system base class

build_targets = []

Targets for make during the build() phase

build_time_test_callbacks = ['check']

Callback names for build-time test

check()

Searches the Makefile for targets test and check and runs them if found.

configure(spec, prefix)

Runs configure with the arguments specified in configure_args() and an appropriately set prefix.

configure_abs_path
configure_args()

Produces a list containing all the arguments that must be passed to configure, except --prefix which will be pre-pended to the list.

Returns:list of arguments for configure
configure_directory

Returns the directory where ‘configure’ resides.

Returns:directory where to find configure
default_flag_handler(spack_env, flag_val)
delete_configure_to_force_update()
enable_or_disable(name, activation_value=None)

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

Parameters:
  • name (str) – name of a valid multi-valued variant
  • activation_value (callable) –

    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(spec, prefix)

Makes the install targets specified by :py:attr:~.AutotoolsPackage.install_targets

install_targets = ['install']

Targets for make during the install() phase

install_time_test_callbacks = ['installcheck']

Callback names for install-time test

installcheck()

Searches the Makefile for an installcheck target and runs it if found.

patch_config_guess = True

Whether or not to update config.guess on old architectures

phases = ['autoreconf', 'configure', 'build', 'install']

Phases of a GNU Autotools package

set_configure_or_die()

Checks the presence of a configure file after the autoreconf phase. If it is found sets a module attribute appropriately, otherwise raises an error.

Raises:RuntimeError – if a configure script is not found in configure_directory()
with_or_without(name, activation_value=None)

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 (str) – name of a valid multi-valued variant
  • activation_value (callable) –

    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

spack.build_systems.cmake module

Bases: spack.package.PackageBase

Specialized class for packages built using CMake

For more information on the CMake build system, see: https://cmake.org/cmake/help/latest/

This class provides three phases that can be overridden:

They all have sensible defaults and for many packages the only thing necessary will be to override cmake_args(). For a finer tuning you may also override:

Method Purpose

build_directory() Directory where to build the package
build(spec, prefix)

Make the build targets

build_directory

Returns the directory to use when building the package

spack.build_systems.intel module

class spack.build_systems.intel.IntelPackage(spec)

Bases: spack.package.PackageBase

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_environment to set the appropriate environment variables.

build_system_class = 'IntelPackage'

This attribute is used in UI queries that need to know the build system base class

components = ['ALL']

Components of the package to install. By default, install ‘ALL’ components.

Writes the silent.cfg file used to configure the installation.

See https://software.intel.com/en-us/articles/configuration-file-format

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

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

Runs the install.sh installation script.

license_comment = '#'

Comment symbol used in the license.lic file

license_files = ['Licenses/license.lic']

Location where Intel searches for a license file

build_directory() Directory where the Makefile is located
build(spec, prefix)

Calls make, passing build_targets as targets.

build_directory

spack.build_systems.perl module

class spack.build_systems.perl.PerlPackage(spec)

Bases: spack.package.PackageBase

Specialized class for packages that are built using Perl.

This class provides four phases that can be overridden if required:

The default methods use, in order of preference:
  1. Makefile.PL,
  2. Build.PL.

Some packages may need to override configure_args(), which produces a list of arguments for configure(). Arguments should not include the installation base directory.

build(spec, prefix)

This attribute is used in UI queries that need to know the build system base class

build_time_test_callbacks = ['check']

configure(spec, prefix)

Runs Makefile.PL or Build.PL with arguments consisting of an appropriate installation base directory followed by the list returned by configure_args().

Raises:RuntimeError – if neither Makefile.PL or Build.PL exist
configure_args()

Produces a list containing the arguments that must be passed to configure(). Arguments should not include the installation base directory, which is prepended automatically.

Returns:list of arguments for Makefile.PL or Build.PL
install(spec, prefix)

spack.build_systems.python module

class spack.build_systems.python.PythonPackage(spec)

Bases: spack.package.PackageBase

Specialized class for packages that are built using Python setup.py files

This class provides the following phases that can be overridden:

  • build

  • install
  • install_lib
  • install_headers

  • install_data
  • sdist
  • register
  • bdist
  • bdist_dumb

These are all standard setup.py commands and can be found by running:

$ python setup.py --help-commands

By default, only the ‘build’ and ‘install’ phases are run, but if you need to run more phases, simply modify your phases list like so:

phases = ['build_ext', 'install', 'bdist']

Each phase provides a function <phase> that runs:

$ python setup.py --no-user-cfg <phase>

Each phase also has a <phase_args> function that can pass arguments to this call. All of these functions are empty except for the install_args function, which passes --prefix=/path/to/installation/directory.

If you need to run a phase which is not a standard setup.py command, you’ll need to define a function for it like so:
