如何使用python.h

Question

我的程序中包含了Python.h，当我编译程序时，它会显示多个错误，告诉我“无法打开几个库” 错误消息如下

我的程序中没有包含任何上述缺失的库

#include<stdio.h>
#include<Python.h>
int main()
{
     Py_SetProgramName(argv[0]);  
     Py_Initialize();
     PyRun_SimpleString("print("hello")");
     Py_Finalize();
     return 0;
}

Answer 1

I did not include any of the above mentioned missing libraries in my program

从技术上讲你做到了。通过包含Python.h，可以有效地包含它所包含和依赖的所有头。如果这些都不存在，那么您的代码就无法编译。您可以找到有关如何将CPython正确构建到Introduction Guide中的更多详细信息

Answer 2

错误消息

Error E2209 C:\Borland\bcc55\INCLUDE\Python.h 7: Unable to open include file 'patchlevel.h'

指示错误（无法打开文件）是由第7行中的文件python.h引起的。您可能没有包含所有这些头文件，但是您的python.h可能包含了这些头文件

但是,

1. 尝试找出这些文件存储在您的计算机上的位置。然后
2. 了解如何告诉编译器在何处搜索其他包含文件，并提供找到文件的位置。如果不这样做，编译器只会查看某些预先配置的目录，在您的情况下，这些目录是不够的
