linux下无法运行

[wang-bin]

mu只能用qt5编，但是vlc依赖qt4的，加载vlc时崩溃

[fzyz999]

我们开发的时候用的是Gentoo Linux，没能重现崩溃的问题，所以希望您能提供些更详细的信息。 可以提供下您所用平台的详细信息吗？Linux发行版名称，vlc版本，qt版本，所播放文件的格式，以及bug重现的方法？ 谢谢

[wang-bin]

linux deepin 2014. libvlccore7, libvlc5, libvlc-dev, qt5.3.1. 程序跑不起来，gdb了才看到vlc去打开libQtGui.so.4崩溃了

[wang-bin]

ubuntu1404也不行

[Harinlen]

目测是我写bass的时候写挂了，我去看看……

[Harinlen]

我这边在Ubuntu 14.04下也测试通过了，没有问题： libvlc5 libvlccore-dev libvlc-dev 均是Ubuntu软件仓库里面的最新安装包。您看一下libvlccore-dev是否安装？ Crashed的结果能否方便的反馈一下？谢谢~

[Harinlen]

我在Ubuntu下重新配置了一边也没能重现这个bug……Qt的输出里面没有什么提示么？ 您可以安装一下完整的VLC试一下。

[wang-bin]

你传一个到百度盘什么的让我试试吧

[Harinlen]

我们重现出这个bug了，正在全力解决这个bug。

[Harinlen]

最后确认是libVLC的依赖问题，不能同时加载Qt4和5的库导致的问题。

[wang-bin]

现在的版本可以运行了

[Harinlen]

新的版本因为是使用了bass而没有使用vlc才可以运行的。VLC的问题估计需要花一段时间去解决。
