[5.10.60.1-microsoft-standard-WSL2] Linker Errors

[keplerj]

Hi!

I have built the library from source on Ubuntu on Windows (5.10.60.1-microsoft-standard-WSL2) and I am trying to run a simple example from the Documentation:

######################################################################
#include
#include <matplot/matplot.h>

int main() {
using namespace matplot;
std::vector x = linspace(0, 2 * pi);
std::vector y = transform(x, [](auto x) { return sin(x); });
plot(x, y, "-o");

 hold(on);
 plot(x, transform(y, [](auto y) { return -y; }), "--xr");
 plot(x, transform(x, [](auto x) { return x / pi - 1.; }), "-:gs");
 plot({1.0, 0.7, 0.4, 0.0, -0.4, -0.7, -1}, "k");

 show();
 return 0;

}
######################################################################

I try to compile it with the following command:

$ g++ -std=c++2a LinPlot.cc -lmatplot -ljpeg

And I receive the following message:

/usr/bin/ld: /usr/local/lib/libmatplot.a(network.cpp.o): in function `matplot::network::process_force_layout()':

collect2: error: ld returned 1 exit status

Any ideas?

The undefined references indicate that there must be some issue with including some of the functionality in nodesoup library.

Any suggestions on how I can make it work?
