Doug,

I was testing boost-1.41 against net-p2p/rblibtorrent before updating. The
pointyhat status for rblibtorrent on FreeBSD 7 and 8 is green. This may
indicate that the issue is a bug in GCC and should be fixed by adding
USE_GCC=4.2+ to all ports that use Boost.

At present I am testing boost-1.42.0-beta1. I'll try to include FreeBSD 6 in
the test cycle.


Just wanted to say that I saw your note, that I appreciate you following 
up, and that I eagerly await your results. :)

 Regards,

I appreciate the response. Is it possible for me to make just the change
you suggested to the libtorrent sources and have it work, or does this
require that boost libs be changed too?

Need help from someone with boost fu + RELENG_6

2010-01-18 Thread Doug Barton 
Howdy,

I recently took over the net-p2p/rblibtorrent* ports with an eye towards
modernizing them, and my ultimate goal of getting a modern version of
qbittorrent working, which I've done.

However I apparently inherited some build problems on 6-stable that I
don't understand, and since I don't have a 6-stable system available I
cannot test fixes for. The problems appear to be boost-related, both
more or less look like this:

In file included from /usr/local/include/boost/thread/future.hpp:12,
 from /usr/local/include/boost/thread.hpp:24,
 from ../include/libtorrent/storage.hpp:45,
 from ../include/libtorrent/peer_connection.hpp:63,
 from peer_connection.cpp:41:
/usr/local/include/boost/exception_ptr.hpp:43: error: looser throw
specifier for `virtual boost::exception_ptr::~exception_ptr()'
/usr/local/include/boost/exception/detail/exception_ptr_base.hpp:27:
error:   overriding `virtual
boost::exception_detail::exception_ptr_base::~exception_ptr_base() throw ()'
peer_connection.cpp: In member function `void
libtorrent::peer_connection::second_tick(float)':
peer_connection.cpp:2989: warning: converting to `int' from `float'
peer_connection.cpp:2993: warning: converting to `int' from `float'
*** Error code 1

The actual logs are here:
http://pointyhat.freebsd.org/errorlogs/i386-errorlogs/a.6.20100117082456/rblibtorrent-0.13.log
http://pointyhat.freebsd.org/errorlogs/i386-errorlogs/a.6.20100117082456/rblibtorrent-devel-0.14.8.log

If anyone can help me out on this I would really appreciate it (and more
importantly so would our users). I'm hoping that since the errors are
basically the same that hopefully the fix will be obvious and simple. :)
