RHEL8.4编译Rust版GStreamer插件提示pkg-config未找到libdw如何解决

我正尝试构建一个基于Rust开发的GStreamer插件，编译过程中遇到如下报错：

The following warnings were emitted during compilation:

warning: `"pkg-config" "--libs" "--cflags" "gstreamer-1.0" "gstreamer-1.0 >= 1.14"` did not exit successfully: exit status: 1

error: failed to run custom build command for `gstreamer-sys v0.17.0 (https://gitlab.freedesktop.org/gstreamer/gstreamer-rs#d203745c)`

报错最后几行提示需要安装libdw，但我在Red Hat Enterprise Linux release 8.4系统中找不到名为libdw的对应软件包，请问该如何解决该编译问题？

问题原因 #

RHEL 8.4系统中没有直接名为libdw的软件包，编译依赖所需的libdw.pc配置文件属于elfutils-devel包，且该包默认存放的CodeReady Linux Builder（CRB）仓库处于关闭状态，导致pkg-config无法找到对应依赖。

操作步骤 #

• 启用CRB仓库
  执行以下命令开启RHEL 8对应的CRB仓库：

  sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
  

• 安装所需依赖包
  安装elfutils开发包以及GStreamer基础开发依赖：

  sudo dnf install elfutils-devel gstreamer1-devel gstreamer1-plugins-base-devel
  

• 验证依赖有效性
  执行以下命令确认pkg-config可以正常识别libdw：

  pkg-config --modversion libdw
  

  命令正常输出版本号即表示依赖配置完成，重新执行Rust项目编译命令即可正常构建。
