使用cmake构建的QGLViewer simpleViewer示例未运行 [英] QGLViewer simpleViewer example built with cmake not running

问题描述

我试图熟悉QGLViewer（ http://libqglviewer.com/ ），所以我安装了它（在Ubuntu 14.04上），而我正在尝试运行simpleViewer（这是提供的示例）。现在，可以使用qmake来构建代码，但是我想使用cmake编译代码，因此我编写了以下CMakeLists.txt：

I'm trying to familiarize with QGLViewer (http://libqglviewer.com/) so I installed it (on Ubuntu 14.04) and I'm trying to run the simpleViewer (which is a provided example). Now, the code can be built using qmake, but I want to compile the code with cmake so I wrote the following 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，这是我得到的错误：

I'm able to build the project but when I launch the executable this is the error I get:

 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问题，我将很高兴！

I'd be glad if someone could explain me what's wrong!

谢谢！

推荐答案

是这样工作的：

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}
)
