How to install gnu ld on mac os x 10.6?

I'm having a lot of trouble compiling the otherwise excellent Contiki OS on my macbook pro (with mac os x 10.6). Contiki actually uses a lot of GNU-specific features and options of GCC, AR, LD, and so on. So I installed those utilities via macports, but it looks like "port install binutils" does 开发者_如何学Gonot install GNU ld, does it ?

So, the question is, how do I get GNU ld on my mac ? Is there a simple alternative to the hard-way (i.e. the wget, configure, make, make install way) ?

As far as I can tell, GNU binutils does not support the Mach-O format. None of the documentation mentions it, and some Googling turns up some recent messages indicating that it is not supported.

Now, you mention the Contiki OS, which looks to me like an embedded operating system. Are you needing to compile to a native executable, or are you trying to cross-compile for some other environment? MacPorts does include several ports of binutils for cross compilation.

$ port info binutils
