使用G ++编译用于Meep的C ++代码

Question

这是我第一次使用Stackoverflow提出问题。 我一直在寻找在ubuntu中使用g ++编译c ++代码的解决方案，并且发现了很多相关内容，但是没有任何内容可以直接回答我的问题...我的目标是能够在c ++中而不是在方案中创建控制文件，但是当我在ubuntu终端中编译，无法找到meep.hpp文件。 到目前为止，我已经使用apt-get和beleive安装了meep，我拥有所有必需的库...这里的任何方式都是我正在用作测试的代码以及我尝试过的命令：

#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;
}

我使用的命令是：

g++ FirstTest.cpp

或如其他线程所说：

g++ -o FirstTest FirstTest.cpp -lmeep

如果有人能指出我正确的方向，我将不胜感激！ 我对Linux还是很陌生

如下面的评论中所述，我最近安装了libmeep-dev，现在获得了以下内容

Answer 1

尝试指向包含目录。 看起来像这样

g++ -o FirstTest FirstTest.cpp -lmeep -I/example/include/path -L/example/lib/path

也许是-I/usr/include -L/usr/lib

这就是您要寻找的东西https://github.com/stevengj/meep/blob/master/doc/docs/C%2B%2B_Tutorial.md
