In commit 68e684d51f the _get_link_args
function was modified from returning a list[str] of arguments, to a
tuple of both that and a modified copy of the entire target's
current/enhanced dependencies (why not just the new ones? I don't know).
However, the existing use of the function was not adapted to this
change, and tried to turn this entire tuple into a node of the command
line. Tuples cannot flatten to lists, and mesonlib.File or
HoldableObjects don't make good command line arguments.
As a result we errored out with:
ERROR: Argument (['-L/path/to/builddir/', '--extra-library=foo'], [<SharedLibrary 25a6634@@foo@sha: foo>, <SharedLibrary 25a6634@@foo@sha: foo>, <SharedLibrary 25a6634@@foo@sha: foo>]) in "command" is invalid
Split out the flags and the dependencies and update the former while
replacing the latter.
