The gcc and g++ versions used to generate the wheel package uploaded to pypi in both x86 and aarch64 architecture about builder HOT 5 OPEN

@ptrblck, sorry to @you again, please take a loot at this, thank you a lot.

What needs to be added is that we found the docker image for building x86, but we did not find the build environment for aarch64.

I'm not involved in the ARM builds, but would guess these images are used:

Thanks a lot, we can split this question into two parts:

1. Decompress the torch wheel package from pypi, and then get the version of gcc according to the .comment section of the dynamic library in whl. Is this method ok? I personally think that the community should not actively modify the .comment section through tools like patchelf.
2. Is it possible to confirm that the gcc in the x86 environment is 9.3.1?

The two questions are very important to us, thank you.

@ptrblck , sorry to @you again, can you help answer the above two questions? Thank you a lot.

You could take a look at the pytorch hud page https://hud.pytorch.org/hud/pytorch/pytorch/v2.0.1 It stores the github actions that built the binaries. You could then choose one workflow, e.g. https://github.com/pytorch/pytorch/actions/runs/4786980664/jobs/8511609240 and view the raw logs: https://pipelines.actions.githubusercontent.com/serviceHosts/7d146c05-69c3-4c20-a0e7-818111670117/_apis/pipelines/1/runs/2882401/signedlogcontent/22?urlExpires=2023-07-02T20%3A20%3A26.3734274Z&urlSigningMethod=HMACV1&urlSignature=tzb%2Bk%2FfRqlCrm19tr%2FDOP0AS%2Fj91SYQbvt8y5OlQqmA%3D
I could see "2023-04-24T13:47:20.3764365Z -- GCC 9.3.1: Adding gcc and gcc_s libs to link line" in the raw log.
