DKMS makes a few assumptions. 1) the source code needs to be in a directory /usr/src/<modulename>-<moduleversion>. So, /usr/src/foo-1.0 for module foo version 1.0. The version field generally matches what's in the MODULE_VERSION() tag of the source code. 2) in that directory, there needs to be a brief dkms.conf file that looks like: PACKAGE_NAME="foo" PACKAGE_VERSION="1.0" BUILT_MODULE_NAME[0]="foo" DEST_MODULE_LOCATION[0]="/kernel/drivers/net" (it can get fancier, but that's enough for most modules). Then you execute: # dkms add -m foo -v 1.0 # dkms build -m foo -v 1.0 # dkms install -m foo -v 1.0 This builds and installs module foo version 1.0 into your currently running kernel's /lib/modules/ tree. If you need to build for a different kernel than the currently running kernel (or architecture): # dkms build -m foo -v 1.0 -k $kernelver -a $arch # dkms install -m foo -v 1.0 -k $kernelver -a $arch Thanks, Matt -- Matt Domsch Linux Technology Strategist, Dell Office of the CTO linux.dell.com & www.dell.com/linux
