按照提示，试了所有的加-fPIC编译选项的方法，还是不行，包括在build.gradle中加cppFlags，在CMakeLists.txt中设置：

set_property(TARGET ${MY_LIBRARY} PROPERTY POSITION_INDEPENDENT_CODE ON)

  1. set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC")
  2. set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC")

最后证明都不行。

CMakeLists.txt是这样的：

  1. cmake_minimum_required(VERSION 3.0)
  2.  
  3. set(DEMO_NAME lidarapp)
  4.  
  5. set(TOP_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../../../../..)
  6. add_subdirectory(
  7.         ${TOP_DIR}/lastools/src/main/cpp/LASlib/src
  8.         LASlib_output_dir
  9. )
  10.  
  11. add_executable(${DEMO_NAME} main.cpp lds_lidar.cpp)
  12.  
  13. # 引用LASlib文件头
  14. include_directories(
  15.         ${TOP_DIR}/lastools/src/main/cpp/LASzip/src
  16.         ${TOP_DIR}/lastools/src/main/cpp/LASlib/inc
  17. )
  18. #target_include_directories(${DEMO_NAME}
  19. #        PUBLIC
  20. #        ${TOP_DIR}/lastools/src/main/cpp/LASzip/src
  21. #        ${TOP_DIR}/lastools/src/main/cpp/LASlib/inc
  22. #        )
  23.  
  24.  
  25. target_link_libraries(${DEMO_NAME}
  26.         PRIVATE
  27.         livoxsdk #${PROJECT_NAME} # livoxsdk
  28.         LASlib
  29.         android
  30.         log
  31.         )
  32.  
  33. # 开始定义动态库libLidarApp.so
  34. set(MY_LIBRARY LidarApp)
  35. # 调试输出详细信息
  36. set(CMAKE_VERBOSE_MAKEFILE ON)
  37.  
  38. # 动态库和可执行程序的差别就在于少了一个main.cpp
  39. add_library(${MY_LIBRARY} SHARED lds_lidar.cpp)
  40. set_property(TARGET ${MY_LIBRARY} PROPERTY POSITION_INDEPENDENT_CODE ON)
  41.  
  42. set(CMAKE_CXX_STANDARD 11)
  43. # arm-linux-androideabi/bin\ld: error: lidarapp/CMakeFiles/LidarApp.dir/lds_lidar.cpp.o: requires unsupported dynamic reloc R_ARM_REL32; recompile with -fPIC
  44. set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC")
  45. set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC")
  46.  
  47. target_include_directories(${MY_LIBRARY}
  48.         PUBLIC
  49.         ${TOP_DIR}/lastools/src/main/cpp/LASzip/src
  50.         ${TOP_DIR}/lastools/src/main/cpp/LASlib/inc
  51.         )
  52.  
  53. # 这个库架构于livoxsdk和LASlib两个库之上
  54. target_link_libraries(${MY_LIBRARY}
  55.         PRIVATE
  56.         livoxsdk
  57.         LASlib
  58.         android
  59.         log
  60.         )

最后经同事提示，在编译so的时候另起一个小文件hello.cpp试试，开始是lds_lidar.cpp只保留了头文件引用和变量声明，结果发现可以编译了，然后一点点加代码，加到最后全部相同了，还是可以。怀疑是文件命名的原因，遂把文件名改了，后来发现又不行了。然后恍悟，应该是同时编译可执行文件和动态链接库的原因，遂注掉上面可执行程序部分，单独编译so库，发现可以了！

加了个条件编译，CMakeLists.txt变这样了：

  1. cmake_minimum_required(VERSION 3.5 FATAL_ERROR)
  2.  
  3. set(BUILD_EXECUTABLE OFF)
  4. message(编译选项 BUILD_EXECUTABLE=${BUILD_EXECUTABLE})
  5.  
  6. set(TOP_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../../../../..)
  7. add_subdirectory(
  8.         ${TOP_DIR}/lastools/src/main/cpp/LASlib/src
  9.         LASlib_output_dir
  10. )
  11.  
  12. if (${BUILD_EXECUTABLE})
  13.  
  14.     set(DEMO_NAME lidarapp)
  15.  
  16.     add_executable(${DEMO_NAME} main.cpp lds_lidar.cpp)
  17.  
  18.     # 引用LASlib文件头
  19.     include_directories(

  34.             android
  35.             log
  36.             )
  37.  
  38. else ()
  39.  
  40.     # so不能和上面的可执行程序同时编译，否则编译so时会报错如下：

  65.             log
  66.             )
  67.  
  68. endif ()

知道的能说说这是CMake的bug还是NDK的bug，还是我用得不对？
