Warnings when building new kernel

[Tony Flaherty]

hi, apologies for the lack of tech knowledge! It's been a while since I had to do anything like this.

Anyhow, I have a L3440 running hpux 11i

hpdev:/> uname -a
HP-UX hpdev B.11.11 U 9000/800

I have the C Compiler installed,
B3901BA B.11.11.12 HP C/ANSI C Developer's Bundle for HP-UX (S800)

And I run Informix Dynamic Server 7.31.FD8

After changing some kernel paramaters as per the Informix release notes, when I build the kernel I get the following warning repeated several times:

(Bundled) cc: warning 480: The -A option is available only with the C/ANSI C product; ignored.

Any advice is greatly appreciated.

You didn't indicate how you are building the kernel but it appears that the -Aa (or -Ac) was added to the config.mk file. This option is supported by your Ansi C compiler but not by the Bundled C compiler -- which is always used to build kernels. In any event, it is ignored by the Bundled C compiler and as long as your kernel source files contain no ANSI C syntax (which would produce an error rather than a warning) then you are fine. It is also possible that your environment contains some variables (e.g. CCOPTS which could be setting the flag). Do an env as root and look for "-A" in any of the variables displayed. If you see any then unset the variable before building your kernel.

ok, I am building the kernel from within SAM, just changed the configurable paramaters and selected Process New Kernel from the menu.

[Tony Flaherty]

I have checked my env output and you were right:

CCOPTS=-Aa -D_HPUX_SOURCE

so I assume I am ok to go ahead and build the new kernel?

[A. Clay Stephenson]

Ideally, unset CCOPTS before invoking SAM although no real harm is being done.

[Tony Flaherty]

OK will do.

Thanks for the help and advice!

Tony.

The advice given solved the problem for me.

Thanks!
