How to see the list of outputs generated by a rule?

Hi,

I've been setting make or configure_make targets, and I find it takes me a few tries to get say out_static_libs pointing at the right name / directory, and each try seems to run the entire build again (it takes several minutes).

Is there an easy way to see all the outputs that did get generated (i.e. Bazel does not know the list upfront, but sees what the commands output)?

For now, I'm manually running configure and make in a locally installed directory, and then exploring the outputs. This has the downside of not using the same options Bazel does.

I was also trying --sandbox_debug, but it appears not print information pointing to the sandbox since the rule in the sandbox doesn't fail, it just doesn't generate what it expects.

Thanks!

After a bunch of investigation, the key realization is you can look into the bazel-bin/<path to library>/copy_<library> folder to see what was generated. So to make sure that is visible and printed out (bazel prints it out), just don't require any outputs, and then navigate to this folder and poke around.

e.g. for openssl via http_archive, it is bazel-bin/external/openssl/copy_openssl

In my case, the out_lib_dir should have been lib64 instead of lib.
