use toolset=darwin, not toolset=gcc.

Please explain. Why would I do that when I've installed gcc separately and not using what came installed on the machine?

From the boost build documentation:

Apple Darwin gcc
The darwin module supports the version of gcc that is modified and provided by Apple. The configuration is essentially identical to that of the gcc module.
The darwin toolset can generate so called "fat" binaries—binaries that can run support more than one architecture, or address mode. To build a binary that can run both on Intel and PowerPC processors, specify architecture=combined. To build a binary that can run both in 32-bit and 64-bit modes, specify address-model=32_64. If you specify both of those properties, a "4-way" fat binary will be generated.

 

I've installed gcc separately. I'm not using Apple's modified version.

But I suspect that you _are_ using Apple's linker (ld), and it does not understand -h.

Why do you suspect that Apple's linker is being invoked?

And why would it not invoke GCC's linker when I've specified the toolset=gcc?
