[honggaoyan]

where can i get the information?

[Steven Schweda]

Does that question make any sense to you?
It makes none to me.

What's a "dlkm"?

[honggaoyan]

hpux kernel module

[Steven Schweda]

I know nothing, but I thought that the kernel
was always built using the bundled C
compiler.

What OS and architecture?
No, you MUST use HP's ANSI C compiler.

This is an intelligence test.  If you know, you can obviously answer the question. ;-)
A quick search by mr google finds it right away.

honggaoyan is writing a device driver (DLKM).
And the kernel no longer uses the bundled C compiler after 11.11.

>aCC is ANSI C compiler?

No, it is a C++ compiler. And A.03.33 is not supported, it is over 7 years old.
While aCC has a -Ae option, it may not be enough to compile a DLKM correctly.
