no binaries found under

Error message

no binaries found under {} (expected files named by cargo target triple)

What it means

The wheel-packing step found no binaries under the given binaries directory that are named by cargo target triple — there is nothing to embed into the wheel. Typically the --binaries-dir points at the wrong location or the release build/copy step hasn't produced/copied the executables yet.

Solutions

1. Point --binaries-dir at the directory containing the triple-named release binaries
2. Run the cargo build/release step that produces the binaries before packing
3. Verify filenames match the expected target-triple naming exactly
