c++ - 执行示例项目时出现 libvlc-qt 错误

Question

我正在使用 qt5 和 ubuntu 13.04

我克隆了 git 存储库 (git clone git://github.com/ntadej/vlc-qt.git)，然后按照自述文件中的步骤操作，这是输出:

tdsxv@tdsxv-M52S-S3P:~/VLCLibrary$ cd build/

然后我用 qtcreator 打开示例(演示播放器)。我编译它但是当我尝试执行时出现错误:

Starting /home/tdsxv/VLCLibrary/examples/demo-player-Debug/src/demo-player...
The program has unexpectedly finished.
/home/tdsxv/VLCLibrary/examples/demo-player-Debug/src/demo-player exited with code 0

如果我尝试在 Debug模式下运行它，我会得到错误:

The inferior stopped because it received a signal from the Operating System.

Signal name : 
SIGSEGV
Signal meaning : 
Segmentation fault

这是 .pro 文件:

TARGET      = demo-player
TEMPLATE    = app

QT          += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

SOURCES     += main.cpp\
               DemoPlayer.cpp

HEADERS     += DemoPlayer.h

FORMS       += DemoPlayer.ui

#LIBS        += -lvlc-qt -lvlc-qt-widgets

# Edit below for custom library location
LIBS     += -L/home/tdsxv/VLCLibrary/build/prefix/include/vlc-qt -lvlc-qt -lvlc-qt-widgets
INCLUDEPATH += /home/tdsxv/VLCLibrary/build/prefix/include/vlc-qt

为什么这个程序不起作用？

Answer 1

对于所有来自互联网的新手，以节省他们的时间。

当您使用 apt-get 安装 libvlc-qt* 时，您将拥有使用 QT4 编译的库(默认情况下)。
问题是您的应用试图同时使用 QT4 和 QT5。
我的解决方案:

/li>

1. sudo add-apt-repository ppa:videolan/stable-daily
sudo apt-get update
sudo aptitude install vlc vlc-datasudo aptitude install libvlc-dev libvlccore-dev

2. 从官方 git 库下载 vlc-qt 库的源代码 https://github.com/ntadej/vlc-qt并使用 QT5 自行构建并运行 make install

3. sudo ldconfig -v
   <强> ldconfig 创建必要的链接和缓存(供运行时链接器 ld.so 使用)到在命令行指定的目录中找到的最新共享库，在文件/etc/ld.so 中。 conf，并在受信任的目录(/usr/lib 和/lib)中。

4. 重建过时的模块缓存并指向 Qt4 二进制文件。您可以在命令行上重置它:

    sudo /usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins/    
   

   或者传递给vlc选项:

   --reset-plugins-cache
   

经过这些步骤，它终于成功了。
