Jetson平台Canon EDSDK与C++适配编译报错求助

我正尝试在Jetson Orin Nano（Ubuntu 20.04 aarch64）上使用官网最新版Canon EDSDK进行C++开发，CLion编辑阶段无报错，但编译时出现大量类型未定义错误（如__int64、WCHAR等）。以下是编译错误日志及CMakeLists.txt配置，求解决思路。

# Set CUDA directory

set(OpenCV_DIR /usr/local/include/opencv4/opencv2)
find_package(OpenCV 4 REQUIRED)

# Add executable
add_executable(InspectorMain
        main.cpp
        headerFiles/Stitcher.h
        headerFiles/camera.h
        headerFiles/general.h
        camera.cpp

# Include directories

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/Lib)

# Link OpenCV libraries
target_link_libraries(InspectorMain ${OpenCV_LIBS})

# Link with the shared library (libEDSDK.so)
target_link_libraries(InspectorMain ${CMAKE_CURRENT_SOURCE_DIR}/Lib/EDSDK/ARM64/libEDSDK.so)

解决思路 #

• 添加跨平台类型定义：EDSDK原本为Windows平台开发，__int64、WCHAR是Windows专属类型。在CMake中添加编译预定义宏，将这些类型映射到Linux标准类型：

  target_compile_definitions(InspectorMain PRIVATE
      __int64=long long
      WCHAR=wchar_t
  )
  

  或者强制编译器包含标准头文件，提前定义这些类型：

  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -include stdint.h -include wchar.h")
  

• 检查EDSDK版本兼容性：确认下载的EDSDK官方ARM64版本是否完整适配Linux aarch64架构。部分版本可能仅提供二进制库，头文件未做跨平台处理，需要更换为官方明确支持Linux ARM的版本。

• 修改EDSDK头文件（可选）：如果头文件无跨平台条件编译，可手动修改EDSDKTypes.h：

  • 将typedef __int64 EdsInt64;替换为typedef int64_t EdsInt64;（需确保包含<stdint.h>）
  • 将typedef unsigned __int64 EdsUInt64;替换为typedef uint64_t EdsUInt64;
  • 将WCHAR替换为wchar_t

• 指定C++标准：在CMake中明确设置C++标准，确保编译器支持现代类型定义：

  set(CMAKE_CXX_STANDARD 11)
  set(CMAKE_CXX_STANDARD_REQUIRED ON)
