Error when building version 2.4.2 on Ubuntu 26.04

[jsf9k]

I'm getting the following error when building version 2.4.2 on Ubuntu 26.04:

In file included from /root/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/aws-lc-fips-sys-0.13.9/aws-lc/crypto/fipsmodule/bcm.c:41:

921 |   return memchr(s, c, n);

Any ideas as to what I can do to get around this failure?

FWIW, I couldn't get version 3.1.1 to build on Ubuntu 26.04 either:

Hi @jsf9k, support of Ubuntu 26.04 is not currently validated. If you want to build efs-utils on Ubuntu 26.04, there is a known issue building aws-lc-fips-sys with GCC 14. It should be fixed in the coming releases after certification completes. You can see "AWS-LC 3 Cryptographic Module" (dynamic and static) still listed on NIST's Modules In Process list.

I tested a workaround building with clangon RHEL 10 that worked. You can try the same and see if it works on ubuntu 26.04.

On RHEL 10, run the following command before make rpm

sudo dnf install -y clang 
export CC=clang CXX=clang++
export CFLAGS="-Wno-unused-command-line-argument" CXXFLAGS="-Wno-unused-command-line-argument"

Thank you for the suggestion @YangjinanHu. Unfortunately switching to clang resulted in a different compile error about discarding const qualifiers.

Are you planning to add pre-built packages for Ubuntu 26.04 soon?

[YangjinanHu]

Thanks for trying that. Supporting Ubuntu 26.04, including pre-built packages, is on our backlog. But I don't have a timeline I can share yet. We'll follow up on this issue here once there's an update.
