As it is, I think we might need more information still - that commandline hides which files are actually used slightly. Could you try explicitly running the c++ command that is being requested, but with the `-Wl,--trace` option added too. That will tell the linker to print what files it opens when it runs the link, and should give us an hint as to which system library is different for your usage than ours.

Sorry, but `-W --trace` is not the same as `-Wl,--trace`. The former is a pair of options used by the compiler (one of which describes the files used by the compiler). The latter is an option passed to the linker, and is what we need. Please try again!
