Hi list, first of all, sorry if this question has been asked before, I can't find a way to search the archives.. Is it possible to build agentpp as singlethreaded? I thought so until I tried it and I am stuck with this error: #ifndef AGENTPP_USE_THREAD_POOL #error AGENTPP_USE_THREAD_POOL must be defined in agent++.h of AGENT++ >= v3.5c #endif Thanks m
