soong: cc_prebuilt_library_static

[Michael Lekman]

It fails to link when using cc_prebuilt_library_static.

cc_prebuilt_library_static {

    name: "libteststatic",

    defaults: ["test-defaults"],

    compile_multilib: "both",

    multilib: {

        lib32: {

            srcs: ["prebuilts/static-lib/lib/libteststatic.a"],

        },

        lib64: {

            srcs: ["prebuilts/static-lib/lib64/libteststatic.a"],

        },

    },

    export_include_dirs: ["include"],

}

cc_library_static {

    name: "libtest2",

    defaults: ["libtest2_defaults"],

    srcs: ["src/test.cpp"],

    whole_static_libs: [

        "libc_logging",

        "libteststatic",

    ],

    include_dirs: ["vendor/test/test/include"],

    export_include_dirs: ["include"],

}

The prebuilt static libs are copied to %OUT/obj/STATIC_LIBRARIES/libteststatic_intermediates/libteststatic.a and %OUT/obj_arm/STATIC_LIBRARIES/libteststatic_intermediates/libteststatic.a but not to out/soong/.intermediates/

What is the error?  Soong won't unnecessarily copy the prebuilt to out/soong/.intermediates if it doesn't need to, it will use it in place if it can.

I get "error: undefined reference to" during linkage. The symbol are located in libteststatic.a

when I replaced cc_prebuilt_library_static with cc_library_static and added the sources and made a build it link ok. 

Second test I copied the two static libs from previous build and made a build with cc_prebuilt_library_static and it fails to link.

clang.real: error: linker command failed with exit code 1 (use -v to see invocation)

Did you resolve this problem? we have the same requirement as you.

Did you make another target (executable/so) link to libtest2, and the linkage failure was reported for that target?
If so, make your target also link to libteststatic.

Meet same error, and solved as above.
