在 pkg-config 搜索路径中找不到软件包 libdw

Question

我正在尝试构建一个基于 Rust 的 gstreamer 插件。但我得到了这些错误：

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)`

Caused by:
  process didn't exit successfully: `/home/saeed/clean/media-plugins/target/release/build/gstreamer-sys-ce7fd93e56356a79/build-script-build` (exit status: 1)

  Package libdw was not found in the pkg-config search path.
  Perhaps you should add the directory containing `libdw.pc'
  to the PKG_CONFIG_PATH environment variable
  Package 'libdw', required by 'gstreamer-1.0', not found
  Package 'libdw', required by 'gstreamer-1.0', not found

warning: build failed, waiting for other jobs to finish...
error: build failed

最后几行说我需要安装 libdw，但我找不到任何像 libdw 这样的库。我的盒子是 Red Hat Enterprise Linux 版本 8.4

Answer 1

在 Red Hat Enterprise 上我必须安装这个包：

sudo yum install elfutils-devel

在 pkg-config 搜索路径中找不到软件包 libdw
