lsst.sconsUtils is developed at https://github.com/lsst/sconsUtils. You can find Jira issues for this module under the sconsUtils component.

Python API reference

Note

Many of the methods defined in this package are injected directly into the base SConsEnvironment. The SConsUtilsEnvironment class exists solely to allow these methods to be documented. The class will not be used when writing SCons files.

lsst.sconsUtils.scripts Module

Classes

BasicSConscript()

A scope-only class for SConscript-replacement convenience functions.

BasicSConstruct(packageName[, ...])

A scope-only class for SConstruct-replacement convenience functions.

lsst.sconsUtils.dependencies Module

Functions

configure(packageName[, versionString, ...])

Recursively configure a package using ups/.cfg files.

Classes

Configuration(cfgFile[, headers, libs, ...])

Base class for defining how to configure an LSST sconsUtils package.

ExternalConfiguration(cfgFile[, headers, ...])

A Configuration subclass for external (third-party) packages.

PackageTree(primaryName[, noCfgFile])

A class for loading and managing the dependency tree of a package, as defined by its configuration module (.cfg) file.

Using sconsUtils without the conda Compilers

If you would like to use sconsUtils without the conda compilers, then put SCONSUTILS_AVOID_CONDA_COMPILERS in your environment with a non-None value. This environment variable will instruct sconsUtils to use the default system compilers and compiler flags.
