[gpfsug-discuss] [EXTERNAL] - Building kernel module on RHEL10

[Laurence Horrocks-Barlow]

Good spot, I agree it should be pulled as a dependency.

Have you raised this as a support call or RFI?

Subject: [EXTERNAL] - [gpfsug-discuss] Building kernel module on RHEL10

Just an FYI so you don't bash your head against a brick wall like I did.
The mmbuildgpl script assumes that which is installed and as they say
assumptions are the mother of all screw ups.

Turns out on RHEL10 when you do a minimal install, which is not part of
the minimal install and it's not a dependency of any of the GPFS RPMs.

The outcome of which is you get cryptic messages about various stuff
being installed but not in the expected location. That's because the
script tests for say the make RPM and then uses which to test its
location but as which is not installed the test fails.

Two options; either the GPFS RPMs should have the which package as a
dependency or mmbuildgpl script should test that it is installed and
warn if it is not.


JAB.
