Compiling c++ code for meep using g++ - c++

Question

this is the first time I've used Stackoverflow to ask a question. I have been searching for solutions to compiling c++ code using g++ in ubuntu and have found lots of related content, but nothing that answers my question directly... My goal is to be able to create control files in c++ rather than scheme, but when i compile in the ubuntu terminal it cannot find the meep.hpp file. so far i have installed meep using apt-get and beleive i have all required libraries... any ways here is the code I am using as a test, and the commands I have tried:
#include <meep.hpp>
using namespace std;
using namespace meep;
double eps(const vec &p) {
if (p.x() < 2 && p.y() < 3)
return 12.0;
return 1.0;
}
int main(int argc, char **argv) {
initialize mpi(argc, argv); // do this even for non-MPI Meep
double resolution = 20; // pixels per distance
grid_volume v = vol2d(5,10, resolution); // 5x10 2d cell
structure s(v, eps, pml(1.0));
fields f(&s);
f.output_hdf5(Dielectric, v.surroundings());
double freq = 0.3, fwidth = 0.1;
gaussian_src_time src(freq, fwidth);
f.add_point_source(Ey, src, vec(1.1, 2.3));
while (f.time() < f.last_source_time()) {
f.step();
}
f.output_hdf5(Hz, v.surroundings());
return 0;
}
the Commands I use are:
g++ FirstTest.cpp
or as said in other threads:
g++ -o FirstTest FirstTest.cpp -lmeep
if anyone can point me in the right direction i would greatly appreciate it! I am still quite new to linux
As mentioned in a comment below i have recently installed libmeep-dev and now get the followning

Answer 1

Try point the include directory.
Looks like this
g++ -o FirstTest FirstTest.cpp -lmeep -I/example/include/path -L/example/lib/path
Maybe it is -I/usr/include -L/usr/lib
