error in 2nd example about matplotlib-cpp HOT 6 OPEN

I faced with same error(

[dr@ramm matplotlib-cpp]$ make
cd examples && g++ minimal.cpp -lpython2.7 -o minimal -std=c++11
cd examples && g++ basic.cpp -lpython2.7 -o basic
cd examples && g++ modern.cpp -lpython2.7 -o modern -std=c++11
[dr@ramm matplotlib-cpp]$ ls examples
basic basic.cpp basic.png minimal minimal.cpp minimal.png modern modern.cpp modern.png
[dr@ramm matplotlib-cpp]$ examples/basic
Segmentation fault (core dumped)

from matplotlib-cpp.

Maybe you could run it in gdb and post a backtrace of the place where the segmentation fault occurs?

from matplotlib-cpp.

Well, you're almost there :) Just

1. Make sure you have checked out the latest commit without modifications
2. Add -g3 to your compiler flags when compiling minimal.cpp
3. Where you used the list command in gdb, use backtrace instead

from matplotlib-cpp.

thanks a lot, smthng weird with env on my OS, solved

from matplotlib-cpp.

With this example, is showed the Segmentation fault

#include <matplotlib-cpp/matplotlibcpp.h>

namespace plt = matplotlibcpp;

int main()
{
  std::vector<double> x = {1.5, 2.5, 3.5, 4.5},
                      y = {1, 3, 2, 4};

  plt::figure();
  plt::plot(x, y, "bo-");
  plt::xlabel("time [s]");
  plt::ylabel("observations [m]");
  plt::title("Matplotlib minimal example");
  plt::legend();
  plt::show();
  // plt::save("plot.png");

  return 0;
}
