amd64 compiler toolchain question

[Andrew Atrens]

Just trying a -

$ make buildworld TARGET_ARCH=amd64 NO_GDB=1


Not sure how far that will get me. I'm assuming I'll get a compiler and
binutils.

I suppose that means I'm getting the basic shared libraries too.

Curious about rtld and friends, and how that will work. Assuming it does
work (big assumption), in theory, will I be able to run 32bit apps as well as 64bit apps, or will everything need to be recompiled ?

Haven't thought about the kernel, yet. Looks like there is one support
file there, and I can cobble a few from FreeBSD-5 ...

Oops. Breakage -

Looks like binutils214 got upgraded, but the compiler is still producing 32bit instructions.
I guess binutils can't handle both ?

Hmm.

Andrew.
