Hey all, think I found a little bug...

I recently was attempting to build 3rd party modules on a 2.6.26.2 source tree after a "make clean" was run on the kernel source tree.

In the past I would run "make oldconfig prepare scripts" and then build and install the 3rd party module. All would work as expected.

And all started well with the 2.6.26.2 tree. The module built without error, but when I went to load it, it responded back with a version error on the console, and the dmesg was: "no symbol version for struct_module".

If I rebuild the entire kernel and modules in the source tree and then build the 3rd party module again, It builds and loads without issue.

I'm hoping this is a bug, as I use the prepare method of setting up source trees a lot. It saves me hours of time on my server farm.

If you have MODULE_VERSIONING enabled then you need to build
the kernel - "make prepare" is in that case not enough.

Ig you have module.symvers around then that will do it.

So the patch to delete the module.symvers from the tree exposed a mistake in my config? Makes since. Just to clarify, I want CONFIG_MODVERSIONS=n in my .config to use prepare? The help on the setting seems to imply that turning it on makes the kernel less picky about modules, but I guess I don't get it...

Will change that setting and test.

Thanks!

Stu
