If for some reason make modules did not create module.symvers then try:
cd /home/lexa/linux make [wait a few minutes as it builds some scripts and starts building kernel code...] hit <Ctrl-C>
then go back and try building your module.
But i have my kernel completely build, including kernel modules.
I get the error about ./Module.symvers only if I specify O=module_build_directory. When I build the module without O= there is not such error, but the object files are created in the same directory as module source, which I want to avoid.
You have to do 'make module_prepare' with your 'O=' set correctly as well, otherwise how will the build system know where to look for the object files to link/build against? thanks, greg k-h
