Title: Tried for you... gcc 4.5.1, Aug 31 gcc 4.6
Post by: vamiot on September 06, 2010, 09:51:03 AM

These two (gcc 4.5.1 &  4.6) are still having fits with futures/asyncs (bomb at runtime, 4.6 a bit more cleanly)
(local rebuild from sources on (uname -a):
Linux Gypsy-IV 2.6.32-25-server #43-Ubuntu SMP Wed Sep 1 10:54:43 UTC 2010 x86_64 GNU/Linux

Note futures are not even in the C++0x supported/unsupported list, see http://gcc.gnu.org/projects/cxx0x.html (concurrency?), does anyone know?

The native gcc support in the current trunk for the library facilities such as futures is listed at http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.200x (http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.200x). For a particular version you'll have to check your local copy of that documentation page, as the gcc website doesn't seem to list the support that shipped with each individual version.

And just for clarity: just::thread does not support g++ 4.5 or later in the current release.

Hi Anthony,

Compatible with g++ 4.3, 4.4 and 4.5 for 32-bit and 64-bit Ubuntu linux (x86/x86_64) targets, making full use of the C++0x support from g++ including rvalue references and variadic templates.

On the other hand my documentation said

Nothing about gcc 4.5.
Which information is more correct?

BTW, readme.txt from my copy says "The just::thread C++ Thread Library v1.0", while there is announcement of V1.3 as a last version
http://www.stdthread.co.uk/forum/index.php/topic,73.0.html
As far as I see that is the latest version, you probably forgot to update readme.txt :)

Thanks.

The current release supports gcc 4.5 (if you install the right .debs); older releases did not, and the message was correct when written. I guess I ought to update the readme and documentation.
