maradydd | Dear LJ Genie: I am in linker hell (Reply)

I'm building a C++ project for an unusual platform, and am having some confusing problems with my libstdc++. For some reason which I cannot fathom, I am getting an absurd number of "undefined reference to..." linker errors for symbols which are indeed undefined in libstdc++.a, but which are definitely defined in libc.a and libgcc.a. Yes, I am linking to both of those. (I know I am, because earlier I was getting some undefined-reference errors to symbols in libgcc.a from the code I'm actually compiling, and when I added -lgcc they went away.)

Any idea what's going on here? Do I need to compile libstdc++ from scratch rather than using the provided binary? (Please, God, let the answer to that be "no".)

ETA: enigmatic ld ordering issues for the lose. Thanks,
