"The files" is not correct if "the files" includes the kernel module, which is installed into $(DESTDIR)/lib/modules/$(KERNELRELEASE), $(DESTDIR) being / by default and $(KERNELRELEASE) being the kernel release you are building against (which in turn is the currently running kernel by default). Please confirm that. If that's not true for the kernel module for you, then that's an error in the build process, which would need to be fixed. The userland admin tools (drbdadm, drbdsetup, drbdmeta) install into $(DESTDIR)/sbin, again $(DESTDIR) being / by default. We do this because for some applications we need to run very early in the boot process, with /usr possibly not yet being available on the system. Everything else does install below /usr/local by default, to be in line with the FHS. It is common to override this by specifying --prefix=/usr (at which point, btw, you don't need to specify --mandir and --infodir, but you probably want --sysconfdir=/etc). > although configure > says: > > checking for /etc/gentoo-release... no > checking for /etc/redhat-release... yes > checking for /etc/slackware-version... no > checking for /etc/debian_version... no > checking for /etc/SuSErelease... no > configure: configured for Red Hat (includes Fedora, RHEL, CentOS). Yes, it's detecting what platform you are building on and sets a few paths accordingly. It would be pointless to look for this below /usr/local. > What am I doing wrong or what is the adviced way to compile kernel module? To compile and install both the userland and kernel components, in your case the recommended steps would be (assuming you are building as non-root): ./configure --prefix=/usr --sysconfdir=/etc --with-km make sudo make install "make install" does invoke depmod, so no need to do that specifically. Hope this helps. Like Phil already wrote, this will be in the User's Guide shortly. Cheers, Florian
