Yeah, it's bizzare, but maybe that is indeed where the bug is.

This is the function that "injects" the --whole-archive stuff:


defineTest(linkAgainstLibrary) {
    unset(target)
    target = $$1

    unset(source_dir)
    source_dir = $$2

    library = $$lower($$target)

    target = $$resolveFinalLibraryName($$target)

    path = $$replace(source_dir, $${ROOT_WEBKIT_DIR}, $${ROOT_BUILD_DIR})/$$activeBuildConfig()

    force_static_libs_as_shared {
            LIBS += -L$${ROOT_BUILD_DIR}/lib -l$$target
    } else {

        mac {
            LIBS += -Wl,-force_load,$${path}$${QMAKE_DIR_SEP}lib$${target}.a
        } else:win32-msvc*|wince*|win32-icc {
            LIBS += /OPT:REF -l$$target
        } else {
            LIBS += -Wl,-whole-archive -l$$target -Wl,-no-whole-archive
        }

        LIBS += -L$$path

        win32-msvc*|wince*|win32-icc {
            POST_TARGETDEPS += $${path}$${QMAKE_DIR_SEP}$${target}.lib
        } else {
            POST_TARGETDEPS += $${path}$${QMAKE_DIR_SEP}lib$${target}.a
        }
    }

    export(LIBS)
    export(QMAKE_LIBDIR)
    export(POST_TARGETDEPS)
    export(CONFIG)
    return(true)
}


What it _should_ do is end up with -Wl,-whole-archive -lWebCore -wl,-no-whole-archive for example, but for some reason maybe $target expands to more for you?

Can you do a qmake -d -d -d run maybe?
