Finding Broken Library Links on Arch Linux (with examples)

1: Scanning directories to find and list packages with broken library links that need to be rebuilt

Code

lddd

Motivation

This use case is helpful when you want to identify packages on your Arch Linux system that have broken library links. By scanning directories, lddd analyzes the dependencies of each package and checks if any library links are broken. This information can be useful to determine which packages need to be rebuilt to resolve the broken links.

Explanation

The lddd command without any arguments scans certain directories on the system, such as /usr/bin, /usr/sbin, /usr/lib, and /usr/lib64. It analyzes the shared library dependencies of each package listed in these directories and identifies packages that have broken library links.

Example Output

package1: library.so => not found
package2: library.so => /usr/lib/library.so
package3: library.so => /usr/lib64/library.so

In this example output, lddd has scanned the directories and identified three packages (package1, package2, and package3) with library links. However, package1 has a broken link as the library library.so cannot be found. The other two packages have valid library links.

By examining the output, you can determine that package1 needs to be rebuilt to resolve the broken library link.
