[lustre-discuss] lustre-2.14.0_ddn136 make fails with: error: passing argument 1 of ‘bio_alloc’ makes pointer from integer without a cast [-Werror=int-conversion]

What client distro/kernel are you using?  Typically, if it is a newer kernel (e.g. Ubuntu24.04) you will need to get a newer version of the client to build with that kernel.

Using gcc 11.4.1 20231218, autogen.sh then ./configure works but make fails here:

Is there a workaround for this?
