Guys,

Did something happen recently with ThreadLocal? I can't find ThreadLocal.h in the latest release of simbody (https://github.com/simbody/simbody.git ). I ask because I try to compile molmodel (which has not changed in forever) I get the below error. Where exactly is ThreadLocal.h?

thanks

sam

Hi, Sam. I think Chris Dembia removed that obsolete code a while back. I sent him an email requesting advice.

Best regards,

Sherm is correct. We removed that class template when removing the pthread dependency, since now we can use C++11 threads. See https://github.com/simbody/simbody/pull/587/files for how you can use C++11 `thread_local` instead. If you would prefer to continue using `SimTK::ThreadLocal`, you can copy it into your own project. You can obtain the header file here: https://github.com/simbody/simbody/blob ... eadLocal.h

Thanks guys!

yea i suspected that might be it but couldn't find anything about it in the github comments. maybe that was back in svn days and somehow i managed to void encountering this issue.
