Hi, Currently one of our client is using a customized Make script so that they can build the kernel module in their buildsystem. Make script follows following steps 1. Create .o for all .c files 2. Creates final module.o with all the above .o files 3. Using modpost creates Module.markers (Below is the command I see getting executed when using 2.6.32 kernel) /lib/modules/2.6.32.58/source/scripts/mod/modpost -i /lib/modules/2.6.32.58/source/Module.symvers -S -K /lib/modules/2.6.32.58/source/Module.markers -M ../l2/Module.markers ../l2/l2_module.o I guess this step creates modulename.mod.c file once successful. 4. Now create modulename.mod.o file. 5. Finally link up everything creating .ko file. Above steps works great with 2.6.32 kernel but When I am trying the same on 3.6 kernel Step-3 doesn't return anything other than Error 1 at the end. Seems Modpost is one tough nut to crack as it has doesn't have any options or debug logs to display its output status. So I built modpost with -g option. In modpost main function read_symbols function is called with input as "/lib/modules/3.6.10/source/Module.symvers" which in turn calls read_elf function which is failing currently. I know its the dirty way where we need to fix makefile for every kernel version. I would like to know is there something which got changed after 2.6.32 kernel which is causing the MODPOST to fail. Any inputs would be of great help. Thanks in advance.
