Arch Linux User Repository

@mindbound You can start by searching for which packages need protobuf and/or python-protobuf as a dependency. For example, with 'pacman -Qi protobuf', and looking at the 'Required By' and 'Optional For' lines. I would bet that it's python-onnx, since it depends on protobuf. Every time that protobuf gets a soname bump you should rebuild python-onnx (and any other AUR packages that depend on it), and it's user responsibility to keep track of this.

@dbermond Well, crap. Any ideas how to find this something?

@mindbound At the time of writing, there is no file named 'libprotobuf.so.32' in the official repositories (protobuf currently ships 'libprotobuf.so.23'). It looks like that you have something built against an outdated libprotobuf.

Build of python-tensorrt package fails with

ImportError: libprotobuf.so.32: cannot open shared object file: No such file or directory

Which version of protobuf is this even referring to? I have protobuf and python-protobuf installed from extra, version 23.3-2 both.

Latest download link (for convenience)

@DavTheRaveUK @mergen @Moebius14 @pwf Package updated. Building fine.

was able to install GA with the following patch (i think... haven't tried it from scratch, and ended up editing a few files in src, but i think this is all the changes):

and actually, cudnn version should now be 8.9 yeah?

@mergen I got the same error when I accidentally downloaded TensorRT version 8.6.1.6 instead of 8.6.0.12 Make sure you download version 8.6.0.12. You can find it under "TensorRT 8.6 EA". Heres the link for your convenience:

I modified the PKGBUILD to new version and sha256sum but I still get an error:
