# A Couple of env vars are available to effect usage of this eclass |
| 16 |
# These are as follows: |
| 17 |
# |
| 18 |
# Env Var Option Default Description |
| 19 |
# KERNEL_DIR <string> /usr/src/linux The directory containing kernel |
| 20 |
# the target kernel sources. |
| 21 |
# BUILD_PARAMS <string> The parameters to pass to make. |
| 22 |
# BUILD_TARGETS <string> clean modules The build targets to pass to make. |
| 23 |
# MODULE_NAMES <string> This is the modules which are |
| 24 |
# to be built automatically using the |
| 25 |
# default pkg_compile/install. They |
| 26 |
# are explained properly below. |
| 27 |
# It will only make BUILD_TARGETS once |
| 28 |
# in any directory. |
| 29 |
# NO_MODULESD <string> Set this to something to prevent |
| 30 |
# modulesd file generation |
| 31 |
|
| 32 |
|
| 33 |
# MODULE_NAMES - Detailed Overview |
| 34 |
# |
| 35 |
# The structure of each MODULE_NAMES entry is as follows: |
| 36 |
# modulename(libmodulesdir:modulesourcedir) |
| 37 |
# for example: |
| 38 |
# MODULE_NAMES="module_pci(pci:${S}/pci) module_usb(usb:${S}/usb)" |
| 39 |
# |
| 40 |
# what this would do is |
| 41 |
# cd ${S}/pci |
| 42 |
# make ${BUILD_PARAMS} ${BUILD_TARGETS} |
| 43 |
# insinto /lib/modules/${KV_FULL}/pci |
| 44 |
# doins module_pci.${KV_OBJ} |
| 45 |
# |
| 46 |
# cd ${S}/usb |
| 47 |
# make ${BUILD_PARAMS} ${BUILD_TARGETS} |
| 48 |
# insinto /lib/modules/${KV_FULL}/usb |
| 49 |
# doins module_usb.${KV_OBJ} |
| 50 |
# |
| 51 |
# if the modulessourcedir isnt specified, it assumes ${S} |
| 52 |
# if the libmodulesdir isnt specified, it assumes misc. |
| 53 |
# if no seperator is defined ":" then it assumes the argument is modulesourcedir |
