Example 1 with ExpansionException

use of com.google.devtools.build.lib.rules.cpp.CcToolchainFeatures.ExpansionException in project bazel by bazelbuild.

the class CppModel method getLinkedArtifact.

/**
   * Returns the linked artifact resulting from a linking of the given type. Consults the feature
   * configuration to obtain an action_config that provides the artifact. If the feature
   * configuration provides no artifact, uses a default.
   *
   * <p>We cannot assume that the feature configuration contains an action_config for the link
   * action, because the linux link action depends on hardcoded values in
   * LinkCommandLine.getRawLinkArgv(), which are applied on the condition that an action_config is
   * not present.
   * TODO(b/30393154): Assert that the given link action has an action_config.
