从Cmake运行编译文件时出现分段错误

Question

我想编译一个依赖于PCL和OpenCV的项目。

的的CMakeLists.txt的样子：

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") 

结果却是分段错误和核心转储。我已阅读Cmake tutorial，但我没有找到问题。 CMake的生成目标文件的所有：

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 
[ 60%] Building CXX object CMakeFiles/pcl_visualizer_demo.dir/image_converter.cpp.o 
[ 80%] Building CXX object CMakeFiles/pcl_visualizer_demo.dir/readInputFile.cpp.o 
[100%] Building CXX object CMakeFiles/pcl_visualizer_demo.dir/pcl_visualizer_demo.cpp.o 
Linking CXX executable pcl_visualizer_demo 

在链接详细信息来看，在不同的目标文件中提到，我解释这又联系。

我错过了什么？

更新

古怪所以使用基本OpenCV函数cv::waitKey和cv::imshow代码的某些部分发生错误，它似乎是与QT according to this和this的问题。

Answer 1

我有类似的问题。最后，我不得不建立PCL没有QT（我也发现了几个职位，说明干扰，但没有找到解决办法）
