使用CMake+pybind11构建Python调用的C++共享库遇错误求助

CMake配置错误 #

无论通过命令行还是CMake GUI生成共享库，均出现相同配置失败问题：

• C/C++编译器识别失败，指定的MinGW gcc.exe无法编译测试程序
• 链接阶段中，MinGW的ld.exe无法识别MSBuild传递的/ERRORREPORT:QUEUE等参数
• 存在WindowsSDKDir属性未定义的警告

当前使用的CMakeLists.txt内容如下：

cmake_minimum_required(VERSION 3.30)

set(CMAKE_C_COMPILER "C:/msys64/mingw64/bin/gcc.exe")
set(CMAKE_CXX_COMPILER "C:/msys64/mingw64/bin/g++.exe")
set(CMAKE_LINKER "C:/msys64/mingw64/bin/ld.exe")

project(SudokuProject)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)

include_directories(${CMAKE_SOURCE_DIR}/include)

file(GLOB GEN_SOURCES "src/gen.cpp")
file(GLOB CHECK_SOURCES "src/check.cpp")
file(GLOB LOGGER_SOURCES "src/logger.cpp")
file(GLOB WRAPPER_SOURCES "src/wrapper.cpp")

add_library(gen SHARED ${GEN_SOURCES})
add_library(check SHARED ${CHECK_SOURCES})
add_library(logger SHARED ${LOGGER_SOURCES})

add_library(wrapper MODULE ${WRAPPER_SOURCES})

target_include_directories(wrapper PRIVATE ${CMAKE_SOURCE_DIR}/include)
find_package(Python3 REQUIRED COMPONENTS Development)
target_include_directories(wrapper PRIVATE ${Python3_INCLUDE_DIRS})
target_link_libraries(wrapper PRIVATE ${Python3_LIBRARIES})

target_include_directories(gen PRIVATE ${CMAKE_SOURCE_DIR}/include)
target_include_directories(check PRIVATE ${CMAKE_SOURCE_DIR}/include)
target_include_directories(logger PRIVATE ${CMAKE_SOURCE_DIR}/include)

target_link_libraries(gen PRIVATE logger)
target_link_libraries(check PRIVATE logger)

set_target_properties(gen PROPERTIES LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set_target_properties(check PROPERTIES LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set_target_properties(logger PROPERTIES LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set_target_properties(wrapper PROPERTIES LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)

pybind11头文件问题 #

包含<pybind11/pybind11.h>时提示无法打开源文件Python.h：

• 最初通过pip安装pybind11，存在<pybind11/stl.h>的错误
• 改用MinGW64安装pybind11后，<pybind11/stl.h>的错误解决，但Python.h找不到的问题仍然存在

已尝试的排查步骤 #

• 先后从官网和MSYS2安装CMake
• 检查PATH环境变量配置
• 在CMake GUI中手动指定编译器路径
• 使用VSCode作为开发环境，不确定是否影响结果
