[lustre-discuss] Compiling lustre 2.12.X with linux kernel 5.10.X and above

[Tung-Han Hsieh]

Dear All,

We tried to compile Lustre-2.12.6, 2.12.8, and 2.14.0 with Linux
kernel 5.10.114 and 5.15.38, the newest releases of the longterm
series of Linux kernel in Linux Kernel Archives:

https://www.kernel.org/

but all failed in configure state. When running this command in:

./configure --prefix=/opt/lustre --with-linux=/usr/src/linux-5.4.192 \
            --with-o2ib=no --disable-server --enable-mpitests=no

it prompted with the error message:

==============================================================================
checking for /usr/src/linux-5.10.114/include/generated/autoconf.h... yes
checking for /usr/src/linux-5.10.114/include/linux/version.h... no
checking for /usr/src/linux-5.10.114/include/generated/uapi/linux/version.h... yes
checking for /usr/src/linux-5.10.114/include/linux/kconfig.h... yes
checking for external module build target... configure: error: unknown; check config.log for details
==============================================================================

The error logs in config.log are attached below.

I am wondering whether there is a plan to port Lustre to Linux kernel
version 5 ? at least the Lustre client part. Upgrading to Linux kernel
version 5 is necessary for us, because the drivers of the embedded
ethernet cards of some newly purchased hardware only available in
Linux kernel version 5.

Thanks very much for your reply in advance.

Best Regards,

T.H.Hsieh
