No, I have an object file which I have compiled with g++, and a
Haskell library which uses symbols from it. I usually just put it on
the ghc command line and that seems to work, but don't know what the
Cabal equivalent of this technique is.

OK, I've attached my cabal file and a transcript of the verbose
output.

$ grep string vectro.cabal
ld-options: this string never appears anywhere as far as i can tell
$ grep string cabal.out
