I seem to remember that '#define BOOST_SYSTEM_NO_DEPRECATED' fixed the system-related errors for me under GCC via MinGW-w64 on Windows. Not sure about the pthread related errors. Not positive that will work btw, but it's worth a try. On Fri, Jun 24, 2011 at 4:04 AM, Wilde, Donald S wrote:

Hi, All -

I am having some challenges mixing boost and c++0x.

My configuration:

Ubuntu 10.04, gcc 4.4.3, boost 1.46.1

I've updated the libraries and headers from Ubuntu's stock boost 1.40 level, and I've tried bjam with and without 'toolset=gcc cxxflags=-std=c++0x'

Either way, my Eclipse reports several errors in the external libraries:

Undefined references to boost::system::generic_category() Undefined references to boost::system::system_category() (both from system and asio error headers) Undefined references to pthread_key_create and pthread_key_delete from asio/detail headers

{ apologies for not giving specific error details but it'd have to come from a screen shot and that's not appreciated on a mailing list }

I do have access to gcc 4.5.1, but it's a custom one for our embedded Atom-based SoC. That is the eventual target, but I haven't seen how to use a specific g++ binary yet.

I did see a bug tracker post in one of my google searches but I haven't been able to get back to it. I understand that this is a known issue and a moving target but I would appreciate it if someone would summarize the current state for me.

Thanks in advance!
