Hi all. I have a doubt... The flow_fetcher component has a struct called Flow_fetcher_app. When I try to resolve flow_fetcher in a c++ component I get the following error: *../../../../../src/nox/component.hh:111: error: incomplete type ‘vigil::applications::Flow_fetcher_app’ used in nested name specifier*
To quit this error I put the Flow_fetcher_app *getInstance* function in Flow_fetcher.hh. But in fetch function the getInstance function is called one more time as the following code: *Flow_fetcher* ff; Flow_fetcher::getInstance(ctx, app); return ff->start_fetch(dpid, request, cb); *But* *using getInstance I get a segmentation fault error.* *What is the function of getInstance? I still confused in that. Can someone help me, please? Sorry if I was not clear. Thanks and regards. -- Ricardo Bennesby da Silva Ciência da Computação - UFAM LabCIA - Laboratório de Computação Inteligente e Autonômica
