Hello!
I have a problem with compiling modules for 2.5.
i wrote a module for 2.4. For 2.5 (51,52,53) it compiles nicely, but insmod complains about invalid format. I have the latest module init tools of Rusty installed.  I'm usin gcc 3.2. Do i have to use any special compiler/linker options or defines or whatever to generate a working module ? what could be the problem ? Even a simple hello-world module doesnt work. Although, i have a working 2.5.53 modular kernel that was built using same tools.

best,
Al.

Well, you can do

cd my_module
echo "obj-m := my_module.o" > Makefile
vi my_module.c
make -C <path/to/kernel/src> SUBDIRS=$PWD modules

That's not too bad (and basically works for 2.4 as well)

I recently tracked down the same problem.

Add a -DKBUILD_MODNAME="yourname" compile option to one of the files,
the new loader requires a module name section. It should be only set
once for each module.

In addition make sure you're using the new style module_init/module_exit
macros instead of init_module/cleanup_module.

P.S.: I agree that the error reporting sucks for this one. It would
be better if the kernel loader give some kind of text message back.

I think we mainly lack of documentation. anybody really followed and
understood this thing or perhaps the author ;-) should
write a/update modules.txt for 'module writers' not for users:

- how to update old style to new style; what needs to be changed ?
- what needs to be done to build own modules outside kernel tree ?
- skeleton for new modules
- dos and dont's

Did I miss s.th. ?
