c++ - 使用 g++ 为 meep 编译 c++ 代码

Question

这是我第一次使用 Stackoverflow 提问。我一直在寻找在 ubuntu 中使用 g++ 编译 c++ 代码的解决方案，并找到了很多相关内容，但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++ 而不是方案中创建控制文件，但是当我在 ubuntu 终端中编译它找不到 meep.hpp 文件。到目前为止，我已经使用 apt-get 安装了 meep，相信我拥有所有必需的库......这里的任何方式都是我用作测试的代码，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

或如其他主题所述:

g++ -o FirstTest FirstTest.cpp -lmeep

如果有人能指出正确的方向，我将不胜感激!我对 linux 还是很陌生

正如下面评论中提到的，我最近安装了 libmeep-dev，现在得到以下内容

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

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