"usd_core-22.3-cp39-none-manylinux_2_17_x86_64" contains unstripped SO's

[alexey-pelykh]

Description of Issue

Shared libraries packaged into the bundle are too big because they are not stripped

Steps to Reproduce

1. pip3.9 install usd-core
2. Examine e.g. libusd_usd-*.so that is ~31.6Mb in size
3. Run strip -s (or at least strip -S) on that file
4. Observe it's being reduced to 10Mb in side

Possibly

... auditwheel repair --strip ...

should do it 🤔

[alexey-pelykh]

Nope, that does break it:

ImportError: /data/venv/lib/python3.9/site-packages/pxr/Tf/_tf.so: ELF load command address/offset not properly aligned

[alexey-pelykh]

Using auditwheel 5.1.2 and patchelf 0.14.5 gives same result: or bloated libraries, or broken ones if stripped

I was experiencing the same issue with a different package and changing auditwheel to batch the calls to patchelf fixed it for me. Now the wheel is much smaller (especially uncompressed) and stripping the libs does not cause the ELF load command address/offset not properly aligned error. I have a PR in for auditwheel here: pypa/auditwheel#376.

In the meantime you could try installing from my branch (https://github.com/aganders3/auditwheel/tree/aa/batch-patch) and using auditwheel repair --strip.
