Tweaked: Although hwloc dynamic shared object plugins may be used in embedded mode, the embedder project will have to manually setup libltdl in its build system so that hwloc can load its plugins at run time. Also, embedders should be aware of complications that can arise due to public and private linker namespaces (e.g., if the embedded project is loaded into a private namespace and then hwloc tries to dynamically load its plugins, such loading may fail since the hwloc plugins can't find the hwloc symbols they need). The embedder project is *strongly* advised not to use hwloc's dynamically loading plugins / libltdl capability. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
