Hello. I'm attempting a newbie skill building exercise rather than solving a particular problem, but I'm missing something obvious. Searching hasnt helped me on this specific point. I imagine that 'make' of the entire kernel source RPM (at the exact version as my Fedora 9 precompiled kernels) should closely duplicate my precompiled kernel modules, for example my ALSA driver module snd-intel8x0.ko However as shown by 'ls' at the last paragraph of this email, I notice that the snd-intel8x0.ko I build using 'make' is 230265 bytes but the precompiled operational one is *much* smaller at 39592 bytes. I am afraid to proceed to 'make install' until these files look similar/identical. Also I notice that if I build the kernel.rpm and then 'rpm -qp --dump' it, then these file sizes *are* identical. So I am wondering what affects the size of the .ko file between 'make' and the built RPM. As a newbie in this area I am far from comprehending the entire kernel.spec or Makefiles system. So it would greatly assist me if someone could give me a pointer what to look at next. Please note that my aim is not to build an rpm. My aim is to become knowledgable enough extract a kernel source tree from a srpm, to be able to 'make' it, and ultimately to be able to 'make' subsections of it, in particular make and install an individual module, without building an rpm. I understand the consequences for my rpm database. Using diff on the output from 'modinfo' on each file gives only these differences < filename: /BIG/HOME/david/rpmbuild/BUILD/kernel-2.6.25/linux-2.6.25.i686/sound/pci/snd-intel8x0.ko > filename: /lib/modules/2.6.25-14.fc9.i686/kernel/sound/pci/snd-intel8x0.ko < vermagic: 2.6.25 SMP mod_unload 686 4KSTACKS > vermagic: 2.6.25-14.fc9.i686 SMP mod_unload 686 4KSTACKS I'm using the reference http://www.tldp.org/LDP/lkmpg/2.6/html/x380.html ("Linux Kernel Module Programming Guide: Building modules for a precompiled kernel"). My complete approach is reproduced below. Probably you can skip the first 3 paragraphs that just show my rpmbuild targets. ~/rpmbuild is a symlink due to insufficient free space on my home drive. By the way, I live in a remote location with poor quality dialup internet so sadly I cannot possibly keep my installation at the latest update of all packages between DVD releases. I'll be really grateful for any tips on the above, thanks.
