Hi Juan, Using mingw with the OSG is not often done so you'll best testing something that few others do so if you spot problems then you'll need to pitch in to help resolve.
As a general note, this error with linking against OpenThreads points to a an issue with how the OSG/OpenThreads was built and what the example is linking against. Normally the OSG is able to keep this all consistent, but if you build the OpenThreads with one configuration, change the configuration and build your application against that new configuration but link against the OpenThreads with the old configuration you might see problems. The include/OpenThreads/Config file is autogenerated and should be consistent. Robert. 2010/11/3 "Juan S.
