使用cmake和pybind11构建示例应用程序时未找到Python.h
我想用pybind11构建简单的应用程序,pybind已经通过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?(已经安装了python-dev和python3-dev,Python.h可用)
回答:
遵循Wenzel Jakob的回答,我想举一个例子,CMakeLists.txt
用于编译本教程中提供的示例:
// example.cpp#include <pybind11/pybind11.h>
int add(int i, int j) {
return i + j;
}
PYBIND11_MODULE(example, m) {
m.doc() = "pybind11 example plugin"; // optional module docstring
m.def("add", &add, "A function which adds two numbers");
}
和
# example.pyimport example
print(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)
现在处于根源运行
cmake .make
现在通过运行python代码
python3 example.py
我还写了一些说明,用于编译/安装pybind11
。
