运行 从 Cmake 编译文件时出现分段错误
Segmentation fault when running compiled file from Cmake
我正在尝试编译一个依赖于 PCL 和 OpenCV 的项目。
CMakeLists.txt 看起来像：
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
project(pcl_visualizer_viewports)
find_package(PCL 1.2 REQUIRED)
find_package(OpenCV REQUIRED)
message("this is my message " ${OpenCV_LIBRARIES} )
message("this is my message " ${OpenCV_INCLUDE_DIRS} )
message("this is my message " ${OpenCV_INSTALL_PATH} )
include_directories(${PCL_INCLUDE_DIRS} ${OpenCV_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
add_executable (pcl_visualizer_demo pcl_visualizer_demo.cpp readInputFile.cpp readInputFile.h defines.h helper.cpp helper.h Image_Safety.h Image_Safety.cpp)
target_link_libraries (pcl_visualizer_demo ${PCL_LIBRARIES} ${OpenCV_LIBRARIES})
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
然而，结果是分段错误和核心转储。我已经通读了 Cmake tutorial，但我没有找到问题所在。 CMake 为所有对象生成目标文件：
Scanning dependencies of target pcl_visualizer_demo
[ 20%] Building CXX object CMakeFiles/pcl_visualizer_demo.dir/Image_Safety.cpp.o
[ 40%] Building CXX object CMakeFiles/pcl_visualizer_demo.dir/helper.cpp.o

[100%] Building CXX object CMakeFiles/pcl_visualizer_demo.dir/pcl_visualizer_demo.cpp.o
Linking CXX executable pcl_visualizer_demo
查看详细的链接信息，提到了不同的目标文件，我将其解释为链接。
我错过了什么？
更新
很奇怪所以错误发生在使用基本opencv函数cv::waitKey和cv::imshow的代码的某些部分，这似乎是QT的问题according to this and this.
我遇到了类似的问题。最后只好在没有QT的情况下搭建PCL（我也找了好几个帖子说干扰，但是没找到解决办法）
