Good afternoon. I am attempting to compile some of our old template code with GCC 4.2.3. The compilation stage is complete, however when I link I see some undefined references to the template class static data members. So far I have been unable to resolve these issues. /cygdrive/s/ipw_products/sw_dev/common/pdc/tgt/rni/ose_ppc/./obj_app//pdc_rni.a(PDCProtocol.o): In function `ServiceManager<DiffservService, DiffservServiceId, 100ul>::release()': ../../../incl/ServiceManager.cxx:278: undefined reference to `ServiceManager<DiffservService, DiffservServiceId, 100ul>::s_used' In the source code we attempt to initialise this static member as follows: template <class Service, class ServiceId, UOPT16 NumberOfServices> Service* ServiceManager<Service, ServiceId, NumberOfServices>::s_used = 0; There does not seem to be a undefined reference for the non static member. Does anyone know how to fix this?
