Re: [m5-users] DPRINTF error

This happens in building the simulator.

In file /mem/cache/coherence/coherence_protocol.cc,

bool
CoherenceProtocol::invalidateTrans(BaseCache *cache, MemReqPtr &req,
                                   CacheBlk *blk, MSHR *mshr,
                                   CacheBlk::State & new_state)
{
    new_state = (blk->status & ~stateMask) | Invalid;
    return false;
}

I was trying to insert
    DPRINTF(Cache, "invalidate");
before return false statement

So that I am notified of cache invalidation.

When I try to build that, I got the following error:g++ -o ALPHA_SE/mem/cache/coherence/coherence_protocol.o -c -pipe -fno-strict-aliasing -Wall -Wno-sign-compare -Wundef -g -O5 -DSS_COMPATIBLE_FP -Iext/dnet -IALPHA_SE -Im5 m5/mem/cache/coherence/coherence_protocol.cc
m5/mem/cache/coherence/coherence_protocol.cc: In static member function `static bool CoherenceProtocol::invalidateTrans(BaseCache*, MemReqPtr&, CacheBlk*, MSHR*, unsigned int&)':
m5/mem/cache/coherence/coherence_protocol.cc:208: error: cannot call member function `virtual const std::string SimObject::name() const' without object
scons: *** [ALPHA_SE/mem/cache/coherence/coherence_protocol.o] Error 1
scons: building terminated because of errors.

I think this is because I used DPRINTF. But I don't know how to fix it.

Can you give the specific context where you're using it? It calls
name() to grab the name of the enclosing SimObject if you use it in a
SimObject method, but there's also a global name() function that it
should find if it's not in a SimObject method.

You can run into problems if you use it in a template of a SimObject
method though.
