Putting them before the packages (including the GHC runtime) that need them, as will happen by default, will cause them to be ignored because they contain no required symbols *at that point* in the link. --whole-archive tells to blindly link the whole static archive in instead of ignoring it. -- brandon s allbery [email protected] wandering unix systems administrator (available) (412) 475-9364 vm/sms
