"make modules_install" with only -devel package installed not a good idea
Last modified: 2015-01-04 17:24:55 EST
Description of problem: I followed the Release Notes for creating a module to build without the kernel source (just the devel package). The build process worked fine... the problem comes from using the same process to call "make modules_install". With a full source tree, all modules are re-installed... with just the -devel package installed, the /lib/modules/*/kernel dir is deleted and recreated without re-installing the modules that were there. The /lib/modules/*/extra dir is filled with the target module. While I'm not sure if this should be a bug with the kernel-devel package, it should _at least_ be a note in the Release Notes... I'd rather see it fixed instead of documented but which component should I change this bug to? Version-Release number of selected component (if applicable): kernel-devel-2.6.12-1.1447_FC4.*.rpm (probably applies to more) Steps to Reproduce: 1. Default install 2. rpm -Uvh kernel-devel-*.rpm 3. make 4. make install # 3&4 are done using a module's source and the makefile below. Actual results: `ls -la /lib/modules/*/kernel/` resulted in nothing being listed. Expected results: `ls -la /lib/modules/*/kernel/` resulted in "arch" "crypto" "drivers" etc... being listed. Additional info: Example Makefile: KERNEL_DIR := /lib/modules/$(shell uname -r)/build MODULE_DIR := $(shell pwd) MAKEFLAGS += --no-print-directory ifeq ("$(KERNEL_DIR)", "") $(error "KERNEL_DIR is not defined.") endif all: modules install: modules_install modules modules_install clean:: @$(MAKE) -C $(KERNEL_DIR) M=$(MODULE_DIR) $@ modules_install:: @$(MAKE) -C $(KERNEL_DIR) -s modules_install
what do you expect the kernel's 'make modules_install' to do with your module ? It has no clue where to install it! For your install: line, just cp your .ko by hand to /lib/modules/`uname -r`/kernel/wherever..
I expected it to put it in 'extra'... It's not the fact of where to put it... it's the fact that it erased the entire existing modules tree! I can do a cp, that's not the part I care about... doing the depmod/generating all the meta-data files (if necessary) is really the problem... Is there a way of calling the makefile to 'add' a module to the tree without deleteing the entire tree?
Let me put this another way: 1) Default install 2) Install kernel-devel-`uname -r`_FC4.i686.rpm 3) cd /lib/modules/`uname -r`/build 4) make modules_install /lib/modules/*/kernel is empty! Next time you reboot, any module you need to load will not be present... Call me crazy, but I don't think this is the best behaviour...
Am I the only one who thinks this is a bug?
