Examples with OptionContextData org.eclipse.cdt.managedbuilder.internal.macros.OptionContextData used on opensource projects

Example 1 with OptionContextData

use of org.eclipse.cdt.managedbuilder.internal.macros.OptionContextData in project arduino-eclipse-plugin by Sloeber.

the class ArduinoManagedBuildGnuToolInfo method calculateOutputs.

/*
	 * The priorities for determining the names of the outputs of a tool are: 1.
	 * If the tool is the build target and primary output, use artifact name &
	 * extension 2. If an option is specified, use the value of the option 3. If
	 * a nameProvider is specified, call it 4. If outputNames is specified, use
	 * it 5. Use the name pattern to generate a transformation macro so that the
	 * source names can be transformed into the target names using the built-in
	 * string substitution functions of <code>make</code>.
	 *
	 * NOTE: If an option is not specified and this is not the primary output
	 * type, the outputs from the type are not added to the command line
