Making a C17 circuit in C++ - c++

Question

I'm trying to simulate a C17 logic circuit in C++ using a Library called LibLCS. Click here to see an example of a digital circuit made with this lib. But isnt working. I cant compile the code and I have no idea why.
#include <lcs/lcs.h>
#include <lcs/nand.h>
#include <lcs/simul.h>
#include <lcs/tester.h>
#include <lcs/changeMonitor.h>
// All libLCS constructs are defined under
// the namespace lcs.
using namespace lcs;
int main()
{
Bus<1> a, b, c, d, e, ga, gb, gc, gd, ge, gf;
Nand<2> nandGate1(ga, (a,b)), nandGate2(gb, (b,d));
Nand<2> nandGate3(gc, (c,gb)), nandGate4(gd, (gb,e));
Nand<2> nandGate5(ge, (ga,gc)), nandGate6(gf, (gc,gd));
ChangeMonitor<5> inputMonitor((a,b,c,d,e), "Input", DUMP_ON);
ChangeMonitor<2> outputMonitor((ge,gf), "Output", DUMP_ON);
Tester<5> tester((a,b,c,d,e));
Simulation::setStopTime(4000); // Set the stop time.
Simulation::start(); // Start the simulation.
return 0;
}
I got the following compilation error:
g++ -o c17 c17.cpp /tmp/cc5TeFfF.o: In function main':
c17.cpp:(.text+0x50a): undefined reference to lcs::Simulation::setStopTime(unsigned int)'

And many more...

From your errors trace that you gave us in comments, I may tell you that you forgot to link your program with your lib.
If your lib is called liblcs.so or liblcs.a, so add this flags to your g++ compilation :
g++ -o c17 c17.cpp -llcs -L"path to the lib folder"
It should works. Or at least it should solve this problem.
