cfg5_generate_rt generator component based output

[SimonReinbold]

Description of the bug:

When using rule cfg5_generate_rt to generate the BSW, the outputs are not sorted into the respective components directories.

Using:

cfg5_generate_rt(
    name = "app",
    components = project_components,
    config_files = project_config,
    dpa_file = "MyEcu.dpa",
    sip = "@sip//:package",
    target_compatible_with = [
        "//tools/bazel_rules/platforms:tricore",
    ],
    visibility = ["//visibility:public"],
)

with MyEcu.dpa snippet:

<GenData>.\Appl\GenData</GenData>

I get the following output in the Bazel output directory:

bazel-out/.../path_to_package
    |- app
        |- generated_headers                (empty)
        |- generated_headers_COMPONENT      (empty)
        |- ...                              (empty)
        |- generated_sources                (empty)
        |- generated_sources_COMPONENT      (empty)
        |- ...                              (empty)
    |- app_cfg_workspace
        |- Appl
            |- GenData                      (<- here are all generated files)
    |- GenData                              (empty)
    |- filter_files.sh

I think generate.bzl#L78 is the culprit here.
It hard-codes that the configurator output is in direct sub directory GenData - but in reality it is inside the created app_cfg_workspace sub directory in the Appl/GenData folder as defined in the .dpa.

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Set the <GenData></GenData> value in the .dpa file to anything other than ..\GenData.

What are the involved Vector tools and their versions?

SIP	R33

Hi @SimonReinbold,
this is currently a known limitation of the rule, but it seems that the documentation was lost in the restructure. I will add it again.
We cannot allow any gendata path since the gendata could be lost within the bazel-bin. Is it possible for you to change the gendata path within the .dpa file?

[SimonReinbold]

Yes I should be able to do that - but if at least the documentation gets restored than it should already help others with the same issue 👍

Thanks

Updated the documentation in #22
