はじめに
- 表示器が無いデバイスでは、ライセンス情報は企業のHPに載せたりする。
- 表示器のあるデバイスでは、ライセンス情報をデバイス内部に持つことが多い。
- yoctoでデバイス内(rootfs)にライセンス情報を持たせる方法を説明する。
方法
- local.confに以下を記載する
COPY_LIC_MANIFEST = "1"
COPY_LIC_DIRS = "1"
LICENSE_CREATE_PACKAGE = "1"
| 項目 | 生成物 |
|---|---|
| COPY_LIC_MANIFEST | usr/share/common-licenses/license.manifest(ライセンス情報の一覧) |
| COPY_LIC_DIRS | usr/share/common-licenses/${PN}(ライセンステキスト+レシピ情報)等 |
| LICENSE_CREATE_PACKAGE | usr/share/common-licenses/${PN}-lic(ライセンステキスト+レシピ情報), usr/share/licenses/(ライセンステキスト) |
例
- bitbake準備
takeshi@X250:~/yocto/poky$ source oe-init-build-env
### Shell environment set up for builds. ###
You can now run 'bitbake <target>'
Common targets are:
core-image-minimal
core-image-sato
meta-toolchain
meta-ide-support
You can also run generated qemu images with a command like 'runqemu qemux86'
Other commonly useful commands are:
- 'devtool' and 'recipetool' handle common recipe tasks
- 'bitbake-layers' handles common layer tasks
- 'oe-pkgdata-util' handles common target package tasks
- local.confでCOPY_LIC_MANIFEST、COPY_LIC_DIRS、LICENSE_CREATE_PACKAGE を有効にしておく
takeshi@X250:~/yocto/poky/build$ cat conf/local.conf | tail -n 3
COPY_LIC_MANIFEST = "1"
COPY_LIC_DIRS = "1"
LICENSE_CREATE_PACKAGE = "1"
- bitbakeする
takeshi@X250:~/yocto/poky/build$ bitbake core-image-minimal
