This is with release 2021.6

Hi @bkmgit , IPP Crypto doesn't support the build with gcc12 now. Please, refer to software requirements.

[bkmgit]

Hi @ElenaTyuleneva Thanks for feedback. Got it to build with Clang 14.0.5 Would pull requests: a) to use GitHub actions CI to do test builds be considered? b) to fixe the above warnings with GCC 12 be considered?

[bkmgit]

There seems to have been a related issue https://github.com/intel/ipp-crypto/issues/16 my builds have been on Fedora 36

Hi @bkmgit. Sorry for delay... a) It's a great idea. Currently we don't have GitHub actions CI, but we can prioritize. b) We are planning to add GCC12 in one of the next releases. Any pull requests are welcome!

Hi @bkmgit,

Could you please try to build again with GCC 12.2? N0 build was disabled in IPP Crypto in the latest releases. Now I see no issue with GCC 12.2

[bkmgit]

Thanks. Will check this, hopefully will also work with GCC 13.
