http://andelf.diandian.com/post/2013-05-22/40050677370 添加新设备
http://wiki.openwrt.org/doc/devel/packages 制作包参考文档
4、OpenWrt取消strip的方法
|
1
|
make
package
/foo/
{clean,compile} V=99 STRIP=
/bin/true
|
也就是说如果默认使用strip破坏了你的程序、库，可以使用STRIP=/bin/true来取消strip操作，直接在Makefile中定义也是可以的

SECTION:=base 在opkg中的段
CATEGORY:=Network 在menuconfig中的分类
DEFAULT := y 在menuconfig中变成默认选中
PKG_RELEASE 类似arch包的尾部子版本,
参考 i2c-gpio-custom , kernel.mk package-default.mk

PKG_NAME - The name of the package, as seen via menuconfig and ipkg
PKG_VERSION - The upstream version number that we're downloading
PKG_RELEASE - The version of this package Makefile
PKG_LICENSE - The license(s) the package is available under, SPDX form.
PKG_LICENSE_FILE-
file
containing the license text
PKG_BUILD_DIR - Where to compile the package
PKG_SOURCE - The filename of the original sources
PKG_SOURCE_URL - Where to download the sources from (directory)
PKG_MD5SUM - A checksum to validate the download
PKG_CAT - How to decompress the sources (zcat, bzcat, unzip)
PKG_BUILD_DEPENDS - Packages that need to be built before this package, but are not required at runtime. Uses the same syntax as DEPENDS below.
PKG_INSTALL - Setting it to
"1"
will call the package's original
"make install"
with prefix
set
to PKG_INSTALL_DIR
PKG_INSTALL_DIR - Where
"make install"
copies the compiled files
PKG_FIXUP - ???

Adding configuration options
If you would like configure your package installation
/compilation
in
the menuconfig you can
do
the following: Add MENU:=1 to your package definition like this:
define Package
/mjpg-streamer
SECTION:=multimedia
CATEGORY:=Multimedia
TITLE:=MJPG-streamer
DEPENDS:=@!LINUX_2_4 +libpthread-stubs +jpeg
URL:=http:
//mjpg-streamer
.wiki.sourceforge.net/
MENU:=1
endef
|
Create a config key in the Makefile:
|
1
2
3
|
define Package
/mjpg-streamer/config
source
"$(SOURCE)/Config.in"
endef
|
|
1
2
3
4
|
And finally you can check your configuration parameters
in
your Makefile
in
the following way: (Note that you can reference to the parameters value with it name prefixed with CONFIG_)
ifeq ($(CONFIG_MJPEG_STREAMER_INPUT_UVC),y)
$(CP) $(PKG_BUILD_DIR)
/input_uvc
.so $(1)
/usr/lib
endif
|
内核模块 autoload
AUTOLOAD:=$(call AutoLoad,30,loop)
|
1
2
3
|
define Build/InstallDev
$(INSTALL_DIR) $(STAGING_DIR)/usr/
include
/madwifi
endef
|
http://wiki.openwrt.org/doc/devel/dependencies 依赖关系，必看
|
1
|
DEPENDS 中 @GPIO_SUPPORT 会在menuconfig中的depends中出现， 而其他子包+kmod-i2c-core则不会出现在里面，将会被opkg的包依赖引用
|
|
1
2
3
4
5
|
EXTRA_KCONFIG := CONFIG_SPI_GPIO_CUSTOM=m (spi-gpio-custom 包)
EXTRA_CFLAGS
AUTOLOAD表示会自动加载，放入
/etc/modules
.d/
FILES 指定模块名
PKG_BUILD_PARALLEL 并行编译
|
http://wiki.openwrt.org/doc/devel/feeds 添加自定义的feed的方法使用 src-link 本地link方式
|
1
2
3
|
src-link customfeed
/home/user/openwrt/project/packages
PKG_FILE_DEPENDS 和 PKG_BUILD_DEPNEDS:=opkg
/host
参考 base-files示例
|
|
1
|
PKG_FLAGS := hold 将会在ipk安装的时候hold, 使用例子 kernel的Makefile, 在 package-ipkg.mk中定义
|
|
1
2
3
|
kernel
/linux/Makefile
:PKG_FLAGS:=hold
libs
/toolchain/Makefile
: PKG_FLAGS:=hold essential
utils
/busybox/Makefile
:PKG_FLAGS:=essential
|
判断包是否被选中
CONFIG_PACKAGE_包名
|
1
|
ifneq ($(CONFIG_PACKAGE_odhcp6c_ext_s46),0)
|
|
1
2
3
4
|
PKGARCH:=all 脚本之类的使用all
PKG_REV 使用git的值
PKG_RELEASE
PKG_BUILD_PARALLEL:=1 并行构建
|
PKG_CONFIG_DEPENDS 为配置依赖, 可依赖HOST的，如python包, python/host 编译，但包中必须有支持host的构建功能
PKG_BUILD_DEPENDS -需要预先构建的软件包，但只是在构建本软件包时，而不是运行的时候。它的语法和下面的DEPENDS一样。
BUILD_VARIANT变量灵活运用参考open包示例
参考opkg和ffmpeg可以得出通过包里的VARIANT变量就可以得来BUILD_VARIANT关联
Build/IncludeOverlay 包含 $(TOPDIR)/overlay/*/$(PKG_NAME).mk 可用于覆盖相同包的参数
|
1
|
feeds
/oldpackages/open/Makefile
: PROVIDES:=open
|
PROVIDES为opkg提供provide，$(PKG_INFO_DIR)/$(1).provides在 package-ipkg.mk中处理
PKG_SOURCE_VERSION 参考 procd 包,使用git取代码，指定版本号
添加不属于Linux源码包的内核模块。在这种情况下，内核模块放在package/目录，跟通常的软件包是一样的。package/Makefile文件使用KernelPackage/xxx定义代替Package/xxx。
这是package/madwifi/Makefile的例子
PKG_INSTALL:=1 https://dev.openwrt.org/browser/feeds/desktop/apps/recordmydesktop/Makefile
http://blog.csdn.net/yangguanghaozi/article/details/17583303
需要注意的是：因为在SmartBox中依赖了libstdcpp以及libpthread，需要在Makefile中添加
|
1
2
|
“
DEPENDS:=+libstdcpp+libpthread”
|
package-ipkg.mk
注：执行makeV=s时可能会显示错误提示：Packagememwatch is missing dependencies for the followinglibraries:libc.so.6，这个错误是因为SDK（OpenWrt-SDK-ramips-for-linux-i686-gcc-4.6-linaro_uClibc-0.9.33.2）/stagin_dir/target-mipsel_r2_uClibc-0.9.33.2/pkginfo目录下没有libstdcpp.provides，新建一个，并添加内容：
|
1
2
3
|
libstdc++.so.6
libstdc++.so.6.0.16
libstdc++.so.6.0.16-gdb.py
|
添加一个libpthread.provides,内容为：
|
1
2
3
|
libgcc_s.so.1
libpthread-0.9.33.2.so
libpthread.so.0
|
内核模块包中 KCONFIG
通过查看include/target.mk 文件中， 查找 .config.override .config.target
还有include下几个kernel相关的mk文件中
其中 .config.target为 openwrt根目录下 make menuconfig 得到的CONFIG_KERNEL_XXX得到的
.config.override为 包模块里 KCONFIG= 得到的
用户自定义的为 $(TOPDIR)/env/kernel-config
最后通过scripts/kconfig.pl 来处理
在package.mk中
可以通过$(TOPDIR)/*/*.mk 来覆盖包
define Build/IncludeOverlay 来替换掉包中的信息

define Feature

endif

package-dumpinfo.mk 定义 $(call Feature,DirectFB)
./xorg/xorg/lib/libX11/Makefile:define Feature/libX11
./xorg/xorg/lib/libX11/Makefile:$(eval $(call Feature,libX11))

make
kernel_menuconfig 直接进行内核的menuconfig
If you want, you can also modify the kernel config
for
the selected target system. Simply run
"make kernel_menuconfig"
and the build system will unpack the kernel sources (
if
necessary), run menuconfig inside of the kernel tree, and
then
copy the kernel config to target
/linux/
/config
so that it is preserved over
"make clean"
call.
使用本地源镜像，用于下载源代码包，如同gentoo的distfiles
echo
"http://local.mirror/path/"
> scripts
/localmirrors
选择xorg
/qt4
包里，需要在全局── Global build settings
Symbol: DISPLAY_SUPPORT [=y]
Prompt: Show packages that require graphics support (
local
or remote)
在Qt选项中才会出现gui相关的选项
$(TOPDIR)
/include/kernel-defaults
.mk中
define Kernel
/Configure/Default
将$(TOPDIR)/.config中的 CONFIG_KERNEL_* 存到 $(LINUX_DIR)/.config.target
通过scrits
/metadata
.pl kconfig 将$(TMP_DIR)/.packageinfo 和 $(TOPDIR)/.config中的 kconfig 转存到 $(LINUX_DIR)/.config.override
即modules.mk中的驱动模块包 KCONFIG:= CONFIG_RTC_CLASS=y CONFIG_RTC_DRV_STMP=m
