Hi, Current compat-wireless build system has some inconveniences for distribution packaging: - In Makefile, KLIB is set to /lib/modules/$(uname -r) which avoids compiling the stack against a non-running kernel. In several other external kernel drivers this can be bypassed by giving KERNELRELEASE=something to "make" but it's not working for compat-wireless. - In gen_compat_autoconf.sh and config.mk there are two calls to $(MAKE) for determining KERNEL_SUBLEVEL: (gen_compat_autoconf.sh) -> SUBLEVEL=$(make -C $KLIB_BUILD kernelversion | sed -n 's/^2\.6\.\([0-9]\+\).*/\1/p') (config.mk) -> KERNEL_SUBLEVEL := $(shell $(MAKE) -C $(KLIB_BUILD) kernelversion | sed -n 's/^2\.6\.\([0-9]\+\).*/\1/p') The problem with that calls is that they're executing make in $KLIB_BUILD for version parsing which creates temporary .tmp files in that directory causing sandboxed builds fail. KERNELRELEASE=something should also allow bypassing those make calls with something like below: if KERNELRELEASE is set SUBLEVEL=$(echo "@KERNELRELEASE@" | sed -n 's/^2\.6\.\([0-9]\+\).*/\1/p') - It's impossible to install the modules under a DESTDIR/BUILD_ROOT. KMODPATH_ARG in Makefile can be used for this purpose but it's not set until the following condition is met: ifneq ($(origin KLIB), undefined) KMODPATH_ARG:= "INSTALL_MOD_PATH=$(KLIB)" I couldn't figure out the evaluation of the expression and simplified it in the following way in my package: Index: compat-wireless-2010-01-06/Makefile =================================================================== --- compat-wireless-2010-01-06.orig/Makefile +++ compat-wireless-2010-01-06/Makefile @@ -1,10 +1,6 @@ export KMODDIR?= updates KMODDIR_ARG:= "INSTALL_MOD_DIR=$(KMODDIR)" -ifneq ($(origin KLIB), undefined) -KMODPATH_ARG:= "INSTALL_MOD_PATH=$(KLIB)" -else -export KLIB:= /lib/modules/$(shell uname -r) -endif +export KLIB:= /lib/modules/$(shell uname -r) export KLIB_BUILD ?= $(KLIB)/build # Sometimes not available in the path MODPROBE := /sbin/modprobe @@ -12,6 +8,7 @@ MADWIFI=$(shell $(MODPROBE) -l ath_pci) OLD_IWL=$(shell $(MODPROBE) -l iwl4965) DESTDIR?= +KMODPATH_ARG:= "INSTALL_MOD_PATH=$(DESTDIR)" ifneq ($(KERNELRELEASE),) This way calling make DESTDIR=/path/to/buildroot install works correctly. I may be misusing the kbuild system but just wanted to share these in case there's anything to be done in upstream, Thanks!
