Illegal relation type 72, for hpux 11i V1

learner_1 — Tue, 28 Feb 2006 07:32:52 GMT

Hi,
I have written a dlkm module for HPUX 11iV1. When I am trying to load the module through kmadmin -L command I am getting following error message -
Illegal relocation type 72 in module /stand/dlkm/mod.d/mymodule
Relocation in module /stand/dlkm/mod.d/mymodule failed.

Can somebody tell me what went wrong.

Thanks.

Hi,
sounds like a coding problem to me. However,
have you had a look at:
http://docs.hp.com/en/dlkm-62001/
Especially the compiler/linker options in the "Sample DLKM WSIO Class Driver" section.

First of all sorry for the typo.... it was "Illegal relocation type 72" instead of "Illegal relation type", well I tried figuring out what is wrong... so to give the complete scenerio.. I am linking many other .o files with the main module file, and creating a final mod.o to load. I am using the command "ld -r" to link these files. So While doing this exercise, couple of times I got "Illegal relocation type 72", and many other times I got " WARNING: MOD: mod_obj_relone: Illegal relocation type 58 in module /stand/dlkm/mod.d/basemod." And "NOTICE: MOD: mod_obj_load: Relocation in module /stand/dlkm/mod.d/basemod failed"...
I couldnt figure out till now the reason for the failure... some files link properly, and the module loads, but a couple files give this error... These files look good otherwise as I tested them independently..

Thanks.

got the solution. I needed to compile the module and the related files with following options... (I was missing +ES1.Xindirect_calls) -

-Wp, -H300000 +Hx0 +R500 +ESsfc +ESssf +XixdU \
