Re: [gem5-users] ruby compilation error

Thu, 21 Jul 2011 23:48:23 -0700

I'm not sure. I'm not all that familiar with SWIG so I don't know if it's doing something wrong, or if I am, or if Nate/Steve/whoever did and it's just being exposed, or...

Is this our bug, or do we need to inform the swig guys ?

While trying to get gcc 4.6.0 working, I found that 2.0.4 introduced a bug that prevented some things from compiling. It produced errors that were different from yours, but you might still want to go back to 2.0.3 or 2.0.2.

Hi Nil,

I use SWIG version 2.0.4....

Just did
scons -c
scons RUBY=true build/X86_FS/gem5.opt

scons: Building targets ...

Still getting errors :(

Hi Carole,
Make sure that your SWIG version is 1.3 or above. I use 2.0.2. If you still 
see error, clean the object files and then try building.

Thanks,

Thanks, Nil.

I am hitting the next weird error message.

build/X86_FS/python/swig/event_wrap.cc: In function 'void
EventQueue_deschedule(EventQueue*, Event*)':
build/X86_FS/python/swig/event_wrap.cc:2983: error: '$self' was not
declared in this scope

The source code says:

SWIGINTERN void EventQueue_schedule(EventQueue *self,Event *event,Tick
when){
       // Any python event that are scheduled must have their


       // internal object's refcount incremented so that the object


       // sticks around while it is in the event queue.


       PythonEvent *pyevent = dynamic_cast<PythonEvent *>(event);
       if (pyevent)
           pyevent->incref();
       $self->schedule(event, when);
   }


Any idea what the error message is about?

thanks,
Carole

I have resolved the issue with gcc 4.4.5 version. Make sure that you
mention CC=/path/to/gcc4.4.5 and CXX=/path/to/g++4.4.5 . I modified the
.bashrc file to create a symbolic link to gcc4.4.5 initially. For some
reason it was still pointing to default gcc (version 4.1.2). I exported CC 
and CXX variables with path to 4.4.5 gcc/g++ binaries. Now things works
fine. However, it fails compile .opt version of the simulator due to memory 
shortage issue.

Hi,

I have tried with different versions of gcc (4.4) and the problem
persists on cluster. Surprisingly it works on my local system.

Thanks,
Nil
