ThreadLocal.h

Simbody is useful for internal coordinate and coarse grained molecule modeling, large scale mechanical models like skeletons, and anything else that can be modeled as bodies interconnected by joints, acted upon by forces, and restricted by constraints.

ThreadLocal.h

Reposting as a single message -- had formatting issues with the prior otherwise identical post.


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

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
