C++ broken on Raspberry Pi?

Tue Apr 16 00:42:01 UTC 2013

I recently bought a Raspberry Pi and have been running FreeBSD 10-CURRENT on it (r249461).  My system is running an image built using Tim Kientzle's Crochet scripts on a FreeBSD/amd64 10-CURRENT build system.  I just tried doing a native build on the Raspberry Pi itself but the buildworld fails fairly early on:

=====

It seems it is having trouble with C++.  The system is using the 3.3 version of clang:

root at pi:/usr/src # c++ -v
FreeBSD clang version 3.3 (trunk 178860) 20130405
Target: armv6-unknown-freebsd10.0
Thread model: posix

I had the same problem with clang 3.2, too.  I've also had problems with C++ building ports.  For example, I can't install devel/subversion because it fails to build databases/db42 due to a C++ problem.

Is this a known problem with the toolchain on armv6?

Cheers,

Paul.
