MacOS Monterey arm64 中包含 Python headers 的位置

Question

我目前正在努力在我的系统上找到 python header，因此无法将它们包含到 C++ 应用程序中

这是我的 cmake 文件 -->

包含#include 的错误消息是common.h Python.h 未找到

找到 python.h 结果

/opt/homebrew/Cellar/boost/1.76.0/include/boost/python.hpp

/usr/local/include 没有 Python.h 和 /opt/homebrew/include

a "which python3" 导致 /opt/homebrew/bin/python3

我的cmake参数如下

-GNinja
-DCMAKE_BUILD_TYPE:STRING=Debug
-DCMAKE_PROJECT_INCLUDE_BEFORE:PATH=%{IDE:ResourcePath}/package-manager/auto-setup.cmake
-DQT_QMAKE_EXECUTABLE:STRING=%{Qt:qmakeExecutable}

-DCMAKE_C_COMPILER:STRING=%{Compiler:Executable:C}
-DCMAKE_CXX_COMPILER:STRING=%{Compiler:Executable:Cxx}
-DCMAKE_TOOLCHAIN_FILE=/Users/ahoehne/repos/vcpkg/scripts/buildsystems/vcpkg.cmake
%{CMAKE_OSX_ARCHITECTURES:DefaultFlag}

感谢您对正确方向的任何帮助或提示。

***编辑***

如果我包括

include_directories(/opt/homebrew/Frameworks/Python.framework/Headers)

至少他似乎找到了 header

但在声明说明符之后产生“预期的成员名称或”；“--> 在 object.h 文件之后，我看到

typedef struct{
    int slot;    /* slot id, see below */
    void *pfunc; /* function pointer */
} PyType_Slot;

typedef struct{
    const char* name;
    int basicsize;
    int itemsize;
    unsigned int flags;
    PyType_Slot *slots; /* terminated by slot==0. */
} PyType_Spec;

在错误代码行...如果我删除 PyType_Slot *slots;该程序可以编译，但我非常怀疑这是一个错误，而是我这边的问题

Answer 1

在我看来，第一个问题是这些行的顺序：

include_directories(${PYTHON_INCLUDE_DIRS})
find_package(Python3 COMPONENTS Interpreter REQUIRED)

所以你引用了一个未知的 PYTHON_INCLUDE_DIRS 变量。

第二个问题是变量名本身。您正在搜索 Python3 包，所以根据 FindPython3 doc

对我来说变量名应该是 Python3_INCLUDE_DIRS

第三个问题是您只搜索 Interpreter，所以无论如何都找不到 headers。

总结一下，请检查是否有类似以下的内容：

find_package(Python3 COMPONENTS Interpreter Development REQUIRED)
include_directories(${Python3_INCLUDE_DIRS})
