使用 cmake 和 pybind11 构建示例应用程序时找不到 Python.h

我想用 pybind11 构建简单的应用程序,pybind 已经用 cmake 安装在我的 Ubuntu 系统中(并进行安装)。我使用这个简单的 cmake 文件:


cmake_minimum_required(VERSION 3.0 FATAL_ERROR)

project(trt_cpp_loader )

find_package(pybind11 REQUIRED)

add_executable(trt_cpp_loader main.cpp)

set_property(TARGET trt_cpp_loader PROPERTY CXX_STANDARD 11)

这是 main.cpp:


#include <iostream>

#include <pybind11/embed.h>

namespace py = pybind11;


using namespace std;

int main(){return 0;}

当我构建它时,我得到:


In file included from /usr/local/include/pybind11/pytypes.h:12:0,

                 from /usr/local/include/pybind11/cast.h:13,

                 from /usr/local/include/pybind11/attr.h:13,

                 from /usr/local/include/pybind11/pybind11.h:44,

                 from /usr/local/include/pybind11/embed.h:12,

                 from /home/stiv/lpr/trt_cpp_loader/main.cpp:2:

/usr/local/include/pybind11/detail/common.h:112:10: fatal error: Python.h: No such file or directory

 #include <Python.h>

          ^~~~~~~~~~

compilation terminated.

我该如何解决这个问题?(python-dev 和 python3-dev 已经安装,Python.h 可用)

对于创建扩展模块的默认情况,您需要使用pybind11_add_module命令(请参阅https://pybind11.readthedocs.io/en/stable/compiling.html#building-with-cmake )。如果目标确实是将 Python 嵌入到可执行文件中,那么您有责任将 Python 头文件和库显式添加到 CMake 中的编译器/链接器命令中。(有关如何执行此操作,请参阅https://pybind11.readthedocs.io/en/stable/compiling.html#embedding-the-python-interpreter )

按照Wenzel Jakob的回答,我想举一个示例CMakeLists.txt来编译本教程中提供的示例:// example.cpp#include <pybind11/pybind11.h>int add(int i, int j) {&nbsp; &nbsp; return i + j;}PYBIND11_MODULE(example, m) {&nbsp; &nbsp; m.doc() = "pybind11 example plugin"; // optional module docstring&nbsp; &nbsp; m.def("add", &add, "A function which adds two numbers");}和# example.pyimport exampleprint(example.add(1, 2))和# CMakeLists.txtcmake_minimum_required(VERSION 2.8.12)project(example)find_package(pybind11 REQUIRED)pybind11_add_module(example example.cpp)现在在根运行cmake .make现在运行python代码python3 example.pyPS我还在这里写了一些关于编译/安装pybind11.
