rustc build for gnueabihf host / target fails at rust_try.o

Working to get a rustc build for armv7 hardfloat machines. Getting the following stdout / error message.

It looks like some recent work has been done @ https://github.com/mozilla/rust/blob/master/mk/rt.mk#L76, nothing looks immediately amiss.

It looks like this may just be a build system glitch, but putting an issue up in case @luqmana or @alexcrichton know of the fix off the top of their heads.

[alexcrichton]

That error message looks a little odd, can you run make VERBOSE=1 and paste the output? Are you sure you don't have local modifications to the makefile?

[itdaniher]

From a fresh copy of master, ./configure --host=arm-unknown-linux-gnueabihf; make yields the following for me. http://itdaniher.com/p?WtqN

GCC info at http://itdaniher.com/p?jbgi.

[luqmana]

Compiling with --host set to a different architecture/os (besides 32/64 linux/unix) than --build doesn't really work right now as far as I know. It doesn't build LLVM properly (i.e cross compile it).

[emberian]

@luqmana @itdaniher is this still an issue? I imagine that compiling for a different host is ill-tested and still broken.

[alexcrichton]

This file has since been removed and moved into the compiler, so closing.
