使用 msdkh264enc 编译 gstreamer 会导致重定位错误

问题描述 投票：0回答：1

我想使用 

msdkh264enc
（在 Linux 上），这要求我按照 文档从源代码构建 gstreamer。

我运行以下配置步骤：

meson setup -Dbad=enabled -Dgst-plugins-bad:msdk=enabled -Dgst-plugins-bad:avtp=disabled build

这会启用 

msdk
（这就是重点）并禁用 
avtp
（因为它无法在我的 Alpine Linux 上构建）。

配置步骤有效并显示所需的输出

Run-time dependency libmfx found: YES 1.28
Has header "mfx/mfxdefs.h" : YES 
Has header "mfxvp9.h" : YES

在构建结束时，我安装在 

/tmp/blah
中：

meson install --destdir /tmp/blah -C build

我有一个 

libgstmsdk.so
，但它的 
ldd libgstmsdk.so
输出看起来存在运行时问题：

ldd /tmp/blah/usr/local/lib/gstreamer-1.0/libgstmsdk.so                                                                                                                                                                            [0]

注意例如如何

libgstreamer-1.0.so.0 => /usr/lib/libgstreamer-1.0.so.0
，这是系统 libgstreamer，它实际上应该指向 
libgstreamer-1.0.so.0 => ./subprojects/gst-plugins-bad/sys/msdk/../../../gstreamer/gst/libgstreamer-1.0.so.0
！

如果我

ldd ./subprojects/gst-plugins-bad/sys/msdk/libgstmsdk.so
（所以库在安装之前），看起来不错。但我需要安装所有这些二进制文件才能使用它们（我无法合理地将 GST_PLUGIN_PATH 指向每个单独的构建目录）！

我在安装步骤中做错了什么？

gstreamer gstreamer-1.0

我认为这与介子如何安装二进制文件无关，而是与运行时的动态链接有关。我不确定是否有更好的解决方案，但设置

LD_LIBRARY_PATH

 在这里有效：
