I have a adder module with trace code which forms a VCD file. 
 
int
{
sc_signal <bool> t_a,t_b,t_cin,t_sum,t_cout;
sc_trace_file *tf;
tf = sc_create_vcd_trace_file("adder_trial_13jan");
full_adder f1("FAWHA");
f1<< t_a << t_b << t_cin << t_sum << t_cout;
driver d1("Generate Waveforms");
d1.d_a(t_a);
d1.d_b(t_b);
d1.d_cin(t_cin);
monitor m1("monitorWaveforms");
m1<< t_a << t_b << t_cin << t_sum << t_cout;
sc_trace(tf,t_a,"t_a");
sc_trace(tf,t_b,"t_b");
sc_trace(tf,t_cin,"t_cin");
sc_trace(tf,t_cin,"t_sum");
sc_trace(tf,t_cin,"t_cout");
sc_start(100,SC_NS);
sc_close_vcd_trace_file(tf);
return(0);
}
 
When I run GTKWAVE. It gives me an error.
It says "No symbols in VCD file....is it malformed? exiting!"
 
Attached is the VCD file with this email.
 
Has anyone come across this error? how can I solve this?
 
Thanks,
