onload 8.1.3.40 fails to build/install from source for Alma 9.4 Kernel 5.14.0.427.1.el9_4.x86_64

[gaurang-lakesidetrading]

Steps:

1. Download source code and extract

2. Attempt to build

cd /root/onload-8.1.3.40/scripts
./onload_install
onload_install: Building Onload.

Attempted to run the script with verbose setting, and it's complaining about the gcc -mharden-sls=all

This is my version of gcc

gcc --version
gcc (GCC) 11.2.0

Based on #209, I also tried

unset CC; CC=/usr/local/bin/gcc; ./onload_install

and

unset CC; ./onload_install

to no effect. I'm not sure where the gcc harden-sls flag is even coming from.

Hi @gaurang-lakesidetrading, as you are using a supported release of Onload (as opposed to the latest commit in this repo) I suggest you e-mail [email protected] and let them know whether you experience this issue with the equivalent Cent OS Stream version, please? Our releases are tested against Red Hat Enterprise Linux but there could be some global configuration difference in the Alma build leading to unexpected compiler version and default option combinations.
