[Scons-users] Chaining generated sources.

[William Blevins]

The builder implementation is irrelevant to the test case, so I recommend
generalizing.  The easiest way to do this would be:

1) Make a <name>.java file that has one or more of the properties that
causes this problem:
    1) The java file creates more than one class file when compiled.
    2) The java class package is not equal to the root package.
2) Write an SConscript that essentially does
    # Psuedo code as follows
    Line 1: env = Environment()
    Line 2: env.Command( "<test_case_input_file>",
"<source_directory>/<package_info>/<test_case_file_name>", Copy("$TARGET",
"$SOURCE") )
    Line 3: env.Java( targets = <build_directory>, sources =
<source_directory> )

This test case provides the following benefits:
1) It is simple and easy to understand.
    Line 1: environment is setup for the example
    Line 2: source "<test_case_input_file>" creates target
"<source_directory>/<package_info>/<test_case_file_name>" named DERIVED.
    Line 3: DERIVED becomes a derived source for the Java builder.
2) This keeps the context local to SCons and removes any external
dependencies: so all code generators are equal~!

Now you just need to validate the produced dependency tree.  Please see the
original email for dependency tree examples.

V/R,
William

If you need help creating this test case then, I could try to create a
patch sometime this week with a link to documentation for contributing to
SCons.
