@sectoidman I got a similar problem. It seems that newer compilers require some explicit inlude in libedgetpu soruce code. I create a PR to the official repo (https://github.com/google-coral/libedgetpu/pull/78). Until it's merged (if ever) I added a patch fixing it. Currently this this state of libedgetpu-git is compilable with gcc 15.1

@tlunter this a working workaround and I we were able to reproduce it.

Hi folks, instead of reverting to the old 24.3 flatbuffers file in the central package repository, I modified the PKGBUILD to pull the required version of flatbuffers, and add that to the libedgetpu Makefile so it installs cleanly without needing to look anything up: https://gist.github.com/tlunter/37a19da8394c0d431df0ed59c54412b5

Hope this helps!

I am also unable to build, even after installing the version of flatbuffers (24.3.25-3-) listed below.

@TonyB I suggest you referring to ArchLinux wiki which is in my opinion an excelent source of knowledge. Specifically, I suggest reading the page describing the archive: https://wiki.archlinux.org/title/Arch_Linux_Archive

By following the wiki, you are able to navigate yourself to this overview of all archived flatbuffers versions: https://archive.archlinux.org/packages/f/flatbuffers/ Then, simple pick a version you'd like to install.

Finally, you should be able to install the flatbuffers e.g. by pacman -U https://archive.archlinux.org/packages/f/flatbuffers/flatbuffers-24.3.25-3-x86_64.pkg.tar.zst

Hope this helps!

@petrbel I'm new to Arch. Could you provide the command to install flatbuffers to 24.3. I tried a few attempts and googled, but had no success.

paulbrause commented on 2025-01-07 23:41 (UTC)

@petbel The "ugly" workaround worked in the end. My Google Coral Accelerator is still not running, but I was able to work around the error with this package. Thank you very much. :)

petrbel commented on 2025-01-07 15:15 (UTC)

@paulbrause Thank you for the submission. I was able to reproduce it. Based on what I've found, blatbuffers has a new release 24.12 (previously 24.3). Unfortunatelly, TensorFlow asserts blatbuffers' version to 24.3 (not only in the used TF version but also in master branch).

I updated libedgetpu-git's requirements so that they reflect this fact and provide a more sensible error message during the package dependency check.

If I may, I suggest downgrading flatbuffers to 24.3 which should solve the problem. Of course, that is only an ugly workaround solution. Nevertheless, unless TensorFlow requirements are updated, I'm afraid I don't know what to do more. Please feel free to suggest any other/better solution. Thanks!

When trying to install this package, the building fails for me:
