Question

我试图熟悉QGLViewer（http://libqglviewer.com/），所以我安装了它（在Ubuntu 14.04上），我试图运行simpleViewer（这是一个提供的示例）。现在，代码可以使用qmake构建，但我想用cmake编译代码，所以我编写了以下CMakeLists.txt：

cmake_minimum_required(VERSION 2.6)
PROJECT(simple_viewer)

SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake_modules)

FIND_PACKAGE(OpenGL REQUIRED)
INCLUDE_DIRECTORIES(${OPENGL_INCLUDE})

FIND_PACKAGE(QGLViewer REQUIRED)
INCLUDE_DIRECTORIES(${QGLVIEWER_INCLUDE_DIR})

FIND_PACKAGE(Qt4 REQUIRED)
INCLUDE(${QT_USE_FILE})
INCLUDE_DIRECTORIES(${QT_INCLUDES})

ADD_EXECUTABLE(${PROJECT_NAME} main.cpp simpleViewer.cpp)
TARGET_LINK_LIBRARIES(${PROJECT_NAME} ${QT_LIBRARIES} ${OPENGL_LIBRARIES} ${QGLVIEWER_LIBRARY})

我能够构建项目但是当我启动可执行文件时，这是我得到的错误：

 dede@dede-P35V2:~/src/simple_viewer/build$ ./simple_viewer 
 *** Error in `./simple_viewer': realloc(): invalid pointer: 0x00007f64d34df840 *** Aborted

如果有人能解释我的错误，我会很高兴！

谢谢！

以这种方式工作：

cmake_minimum_required(VERSION 2.6)
PROJECT(simple_viewer)

SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake_modules)

FIND_PACKAGE(OpenGL REQUIRED)
INCLUDE_DIRECTORIES(${OPENGL_INCLUDE})

FIND_PACKAGE(QGLViewer REQUIRED)
INCLUDE_DIRECTORIES(${QGLVIEWER_INCLUDE_DIR})

FIND_PACKAGE(Qt4 REQUIRED)
INCLUDE(${QT_USE_FILE})
INCLUDE_DIRECTORIES(${QT_INCLUDES})

ADD_EXECUTABLE(${PROJECT_NAME} main.cpp simpleViewer.cpp)

TARGET_LINK_LIBRARIES(${PROJECT_NAME}
  ${QGLVIEWER_LIBRARY} 
  ${QT_QTXML_LIBRARY} 
  ${QT_QTOPENGL_LIBRARY} 
  ${QT_QTGUI_LIBRARY} 
  ${QT_QTCORE_LIBRARY} 
  ${OPENGL_gl_LIBRARY} 
  ${OPENGL_glu_LIBRARY}
)

用cmake构建的QGLViewer simpleViewer示例未运行
