<div>do we need to compile with the <span style="font-family:arial,sans-serif;font-size:13px">-DCBC_THREAD_SAFE -DCBC_NO_INTERRUPT switches or they're already enable by default ?</span></div><div><span style="font-family:arial,sans-serif;font-size:13px"><br>
</span></div><div><span style="font-family:arial,sans-serif;font-size:13px">Also, I've read, in one of the past mails of this thread, that maybe some cut generators could be not thread safe... </span></div><div><span style="font-family:arial,sans-serif;font-size:13px">is it still true ?

It would be more work to enable CBC_THREAD_SAFE by default as the standalone solver normally can read commands from stdin and environment variables. CBC_THREAD_SAFE switches that ability off. To make Cbc threadsafe out of box AND still allow parsing commands would be boring work - maybe a week.<br>
<br>
I never plan - especially releases and I never fiddle too much with configuration. So until next release you could just use svn and then no patches are needed - just svn checkout ...../2.8 and add<br>
<br>
-DCBC_THREAD_SAFE -DCBC_NO_INTERRUPT<br>
<br>
to configure.<span><font color="#888888"><br>

Great,<br>
that exactly what I needed!<br>
My preliminary tests show that cbc works as intended :-)<br>
When do you plan to make a new 2.8 release?<br>
And could you either include a configure option for thread safety, or, even better, just enable CBC_THREAD_SAFE by default?<br>
Or do you need more testing for that?<br>
Ideally, we'd like to use our framework without any patches, and I think that would be the easiest if cbc was threadsafe out of the box.<br>
