[gem5-users] Problem reading OutVcState and OutputUnit classes from RoutingUnit class in Garnet2.0

[Idris M. Umar]

Good day to all,

I wanted to read the public members "get_credit_count()" in OutVcStatec class from the RoutingUnit class using the code lines below

OutVcState element;
int credit_size = element.get_credit_count();

but receives the error underneath:

build/Garnet_standalone/mem/ruby/network/garnet2.0/RoutingUnit.cc: In member function 'int RoutingUnit::outportComputeXY(RouteInfo, int, PortDirection)':
build/Garnet_standalone/mem/ruby/network/garnet2.0/RoutingUnit.cc:188:5: error: 'OutVcState' was not declared in this scope
OutVcState element;

int credit_size = element.get_credit_count();
^
cc1plus: all warnings being treated as errors
scons: *** [build/Garnet_standalone/mem/ruby/network/garnet2.0/RoutingUnit.o] Error 1

I tried to read instead from the OutputUnit class but receives the following error:

build/Garnet_standalone/mem/ruby/network/garnet2.0/RoutingUnit.cc: In member function 'int RoutingUnit::outportComputeXY(RouteInfo, int, PortDirection)':
build/Garnet_standalone/mem/ruby/network/garnet2.0/RoutingUnit.cc:187:16: error: aggregate 'OutputUnit element' has incomplete type and cannot be defined

cc1plus: all warnings being treated as errors
scons: *** [build/Garnet_standalone/mem/ruby/network/garnet2.0/RoutingUnit.o] Error 1
scons: building terminated because of errors.

NOTE: I tried using the friend class, but it still failed to compile, whereas I have no problem with other classes like flitBuffer.

Can someone please help?
