嵌入python3.6，在C+中带有MinGW+；链接失败 在Wi1064位系统中，在C++中嵌入Python 3.6。 Python由Python-3.6.1-amd64.exe安装。 CMakeList.txt如下所示 cmake_minimum_required(VERSION 3.8) project(EmbedPython) set(CMAKE_CXX_STANDARD 11) set(SOURCE_FILES main.cpp) find_package(PythonLibs REQUIRED) include_directories(${PYTHON_INCLUDE_DIRS}) add_executable(EmbedPython ${SOURCE_FILES} ${PYTHON_INCLUDE_DIRS}) target_link_libraries(EmbedPython ${PYTHON_LIBRARIES})

CMake找到了Python包

PYTHON_INCLUDE_DIR C:/Program Files (x86)/Python36/include
PYTHON_LIBRARY C:/Program Files (x86)/Python36/libs/python36.lib

它在谈论API问题

下面的错误就是我所面临的

我也有同样的问题

问题可能是因为使用了32位MinGW和64位Python。您应该安装32位版本的python

希望它对您有用：-）
我遇到了完全相同的问题，只是在尝试从Python手册构建时遇到了Python 3.7

我的系统是64位Windows，安装的Python是64位3.7（来自Anaconda3），编译器是32位MingW5.3.0（来自Qt5.11）

对我来说，最简单的解决方案如下：


从第页下载
将该归档文件的内容放入正在构建的项目中的文件夹中
不要安装该归档文件中的任何内容，并将其放到系统路径上
使用：
-L“path/to/folder/”
使用
-l“python37”
将python库添加到链接器中（用下载的任何版本替换
37
）
如前所述（这很难找到！），添加一个定义，使用
-DPy\u BUILD\u CORE\u BUILTIN=1
（也可以在
\include
-ing Python头之前编写
\define DPy\u BUILD\u CORE\u BUILTIN 1
，尽管我不建议这样做）
使用
-I“path/to/include”
提供Python头的路径。我使用了来自Anaconda的一个，例如
-I“c:/Users/user/Anaconda3/include/”
。任何安装的标题都可以，只需确保其来自同一版本（也可以使用较旧版本的标题，但这可能会导致时空连续体破裂）
如本手册所述，确保将
#include
放在任何其他include之前

作为补充说明，如果您只给它一个“dll”文件，那么多年来，MinGW链接器（ld）是完全满足的。如果没有库，只执行动态链接，则不需要“lib”或“a”。这就是为什么我刚刚告诉链接器使用
python37

实际上，它需要查找像
python37.lib
，
python37.dll
&
libpython37.a
这样的文件

还请注意，“可嵌入的zip”只是嵌入Python所需的最小值

最后一点，与前面所述相反，只要库使用普通的C接口，从GCC链接到使用MSV编译的库（反之亦然）是没有问题的，因为该接口几乎是任何给定平台上跨不同编译器兼容的唯一东西

这正是Python使用C接口进行扩展和嵌入的原因所在（除此之外，连C++）允许使用任何工具集以任何语言编写的代码与Python接口。
请显示您的CMakeLists.txt和
make VERBOSE=1
的输出。另外，请不要发布文本图像。@n.m.我添加了make
VERBOSE=1的输出，并从CMake GUI中删除了图像。您需要使用
target\u link\u库
add_executable
允许您指定源，而不是库。您可以使用MinGW构建项目，但使用python导入的库
.lib
，它是用于MSVC的。您可能需要将其转换为MinGW，就像在那个问题中：是否可以显示
${PYTHON_LIBRARIES}
内容？为了扩展@Tsyvarev，默认情况下，Python是用VStudio编译的。因此，除非您使用MinGW从源代码构建扩展，否则最简单的方法是使用VStudio构建扩展（假设没有与使用它相关的限制），等等：使用上列出的相同版本。
