Kernel Config Error

[Bob Verity]

I am getting an error as follows when trying to build a new kernel:
Config: make did an exit (1)

I don't under stand what is causing the error.
Any suggestions?

Thanks

Hi Bob

What commands are using to re-build kernel? Did you get this error after running mk_kernel? Can you post the parameter(s) & value(s) you are changing.

Did you manually build the kernel or through SAM? What parameter did you changed? Do you try to change back the parameter and see if it works?

[Bob Verity]

I get the message when I build it through SAM or mk_kernel. I have tried to only change something simple like maxusers 32 -> 64. The error is not very specific, but references the following:

cannot build kernel using /usr/sbin/config. The standard output of the command is shown below:
config: make did an exit(1)

the commmand exitted with exitcode -71.

Do you see any other error/warning message before the "*** Error exit code"?
Did you make any change like OS upgrade recently? If yes, do you check the patch prerequisite?

Hi Bob

This is more a stab in the dark than anything but look at the config man page, might point you in the right direction.

It appears from what you said there is a problem with the make command which is called by the config command. Its possible that some of the conf files (/usr/conf/*) that it needs are missing, corrupted or unreadable??

Also have a look in /stand/build & see if mk_kernel has managed to create files such as conf.o, tune.h etc

The mk_kernel has output such as
Generating module: krm...
Compiling conf.c...
Loading the kernel...
Generating kernel symbol table....

How far does it get before the error message appears?

Did you make any change like O/S upgrade recently?
Do check_patches and take a look at the /tmp/check_patches.report. It may help you.

I would have all my data backed up and a make_tape_recovery tape on hand.

It would appear something aweful might have happened to your system.

At the very least you may have a corrupted system file and I'd be hunting for a backup of the /stand filesystem so you can restore that.

From now on, take a backup of /stand before making any move.

You can back up /stand to a vxfs filesystem, but you can't boot off of it. At this point, I'd be making tapes.

HP-UX 10.20, 11.00 or 11.11?

The first thing I would doing is to see if you can generate a new kernel from the existing one.

# cd /stand/build
# /usr/lbin/sysadm/system_prep -s system
# mk_kernel -s system

This will tell you if some of the config files may have got corrupted.

Another common 'gotcha' is making a 'backup' file in a kernel config directory, such that the kernel tries to link both, similar, files which almost always fails.
