无法从源代码制作 vlc：libssh 错误

我尝试vlc-2.1.5使用以下配置命令从源代码安装。

./configure --prefix=/usr/ --disable-vlc --disable-lua --disable-mad --disable-swscale --disable-postproc --disable-xcb --disable-alsa

配置完美执行，没有错误。但是当我尝试时make，我遇到了这些错误。

然后我尝试了这个链接，但又出现同样的错误。

我的操作系统发行版是 Debian 7.5。我应该怎么做才能让错误消失？

答案1

所有这些未定义的符号 ( LIBSSH2_ERROR_EAGAIN, ...) 属于libssh2。您需要安装该库才能编译 VLC。由于某种原因，./configure脚本没有警告您这一点......

您可以libssh2从其网站下载，或者最好使用包管理器来下载。例如，与apt-get...

$ sudo apt-get install libssh2-1 libssh2-1-dev

如果您手动编译它，您可能会遇到必须安装的其他依赖项。脚本configure应该告诉你这一点。

现在，另一个解决方案可能是简单地禁用 VLC 的 SFTP 支持：

./configure --disable-sftp --prefix=/usr/ --disable-vlc --disable-lua --disable-mad --disable-swscale --disable-postproc --disable-xcb --disable-alsa

作为旁注，请记住禁用功能不是依赖问题的实际解决方案...最终，您将不得不处理它们（或使用包管理器，在这种情况下，这显然是最合适的解决方案）。
