I can pass options to the linker using cc with the -Wl option. For example:



cc -Wl,-rpath -Wl,/usr/local/lib


That will invoke the linker with -rpath /usr/local/lib



How can I do the same with ghc?



Also how can I also direct ghc to use a different linker than its default linker? For instance, if ghc is configured to use /usr/bin/ld, how can I tell it to use /usr/local/bin/ld instead? One way to do that with cc is:



cc -B/usr/local/bin

  • Haven't tried this, but according the ghc manual, -optl should let you pass options, and -pgml should let you use a different linker.

  • These are good hints - thanks. The docs organization don't make it easy to search all the options very easily. There's some idiosyncracies with these options I'm trying to work through (e.g., -optl -B/usr/local/bin or -optc -B/usr/local/bin don't seem to "work" - odd error: /usr/local/bin/settings: openFile: does not exist). I'll work through the oddities and craft an answer.

I think you can do ghc -optl-rpath -optl/usr/local/lib
and ghc -optc-B/usr/local/bin.
