What Hacker News says
11 sourcesIf you're using dynamic linking, the following two tools will come in very handy:
- pldd (https://man7.org/linux/man-pages/man1/pldd.1.html) shows the actual dynamic libs linked into a running process. (Contrast this with ldd, which shows what the dynamic libs would be based on the current shell environment).
- libtree (https://github.com/haampie/libtree) which shows dependencies similarly to ldd, but in tree format.
In Picking Glibc Versions at Runtimesee also: https://github.com/haampie/libtree for ldd(1) output as a tree for transitive dependencies
In Binsider – A TUI for analyzing Linux binariesThe first suggestion under the `# Install` header is to use a prebuilt binary like:
https://github.com/haampie/libtree/releases/download/v3.1.1/...
The only verification provided is a sha256sum provided in the README, there's no way to confirm what source code or compiler was used to produce the binary, and no way to verify the binary was produced by that github user / that the README sha256 I was served was untampered with.
I would propose that the 'unsafe' curl method is in fact probably safer than the recommended-first choice in the README.

Search order:
glibc: rpath > LD_LIBRARY_PATH > runpath > ld.so.cache > default paths.
musl: LD_LIBRARY_PATH > rpath=runpath > default paths.
Search path inheritance:
glibc: rpaths are inherited: When exe depends on libx depends on liby, then liby first considers its own rpaths, then libx's rpaths, then exe's rpaths. HOWEVER if liby specifies runpath, it will not consider rpaths from parents.
musl: rpaths and runpaths are the same and always inherited.
I verified the glibc/musl sources when writing https://github.com/haampie/libtree
