为 Linux 嵌入式开发环境 (LEDE)（与 OpenWRT 相同）编译自定义包

Question

Hi all,

平台：x86_64

我成功安装了 Linux 嵌入式开发环境 (LEDE) x86/64（与 OpenWRT 相同）到我的虚拟机。

我使用 SDK 为 Linux 嵌入式开发环境 (LEDE) 开发了自定义包 "Hello World" 并对其进行了交叉编译。然后，在我的虚拟机上测试它，它工作。但是，然后我有自己的代码要移植，即用于 c 中的原始数据包嗅探器，我想移植该代码。因此，我在用于 "Hello world" (helloworld.c) 的同一个文件下复制了相同的代码。再一次，我成功地交叉编译了新的二进制“*.ipk 格式”，然后将它发送到我的 LEDE 虚拟机上并做了 opkg install xxxxxx.ipk。它安装了，但输出相同。我是说 "Hello world".

我不知道怎么办。因为，这次代码变了。然后，再次为测试写了一个简单的阶乘代码并再次。在虚拟机中测试期间。我发现它不起作用，因为再次输出相同的结果，即 "Hello world".

文档：Hello world package for LEDE using LEDE Source 我正在使用 SDK 而不是 source.I 进行开发，遵循文档中的所有内容，不包括源代码编译和所有内容。

SDK 文档：Compile custom package using SDK

Hello World 代码的 Makefile：

include $(TOPDIR)/rules.mk

# Name, version and release number
# The name and version of your package are used to define the variable to point to the build directory of your package: $(PKG_BUILD_DIR)
PKG_NAME:=helloworld
PKG_VERSION:=1.0
PKG_RELEASE:=1

# Source settings (i.e. where to find the source codes)
# This is a custom variable, used below
SOURCE_DIR:=/home/buildbot/helloworld

include $(INCLUDE_DIR)/package.mk

# Package definition; instructs on how and where our package will appear in the overall configuration menu ('make menuconfig')
define Package/helloworld
  SECTION:=examples
  CATEGORY:=Examples
  TITLE:=Hello, World!
endef

# Package description; a more verbose description on what our package does
define Package/helloworld/description
  A simple "Hello, world!" -application.
endef

# Package preparation instructions; create the build directory and copy the source code. 
# The last command is necessary to ensure our preparation instructions remain compatible with the patching system.
define Build/Prepare
        mkdir -p $(PKG_BUILD_DIR)
        cp $(SOURCE_DIR)/* $(PKG_BUILD_DIR)
        $(Build/Patch)
endef

# Package build instructions; invoke the target-specific compiler to first compile the source file, and then to link the file into the final executable
define Build/Compile
        $(TARGET_CC) $(TARGET_CFLAGS) -o $(PKG_BUILD_DIR)/helloworld.o -c $(PKG_BUILD_DIR)/helloworld.c
        $(TARGET_CC) $(TARGET_LDFLAGS) -o $(PKG_BUILD_DIR)/ $(PKG_BUILD_DIR)/helloworld.o
endef

# Package install instructions; create a directory inside the package to hold our executable, and then copy the executable we built previously into the folder
define Package/helloworld/install
        $(INSTALL_DIR) $(1)/usr/bin
        $(INSTALL_BIN) $(PKG_BUILD_DIR)/helloworld $(1)/usr/bin
endef

# This command is always the last, it uses the definitions and variables we give above in order to get the job done
$(eval $(call BuildPackage,helloworld))

Answer 1

我再次交叉编译了相同的代码并使用 LinkIt Smart 7688 对其进行了测试，一切都按预期工作。所以，我认为我为测试创建的 LEDE 虚拟机出了点问题。

LinkIt Smart 7688: It is an open development board which is based on OpenWrt Linux distribution and MT7688. The platform also offers options to create device applications in Python, Node.js and C programming language.

So, I think It is one of the best board available for IoT things within 12.90 US Dollars.

Answer 2

我在openwrt中添加自定义包成功，这是我的Makefile，希望对你有帮助

include $(TOPDIR)/rules.mk

PKG_NAME:=viva
PKG_VERSION:=1.4
PKG_RELEASE=$(PKG_SOURCE_VERSION)
PKG_MAINTAINER:=Vishal <yourname@domain.for.your.name>
PKG_LICENSE:=ISC

include $(INCLUDE_DIR)/package.mk

define Package/viva/default
  CATEGORY:=Network
  SUBMENU:=Web Servers/Proxies
  TITLE:=Webpage for package creation
endef

define Package/viva
  $(Package/viva/default)
  DEPENDS:=+uhttpd
endef

define Package/viva/description
    A web page used for illustrating package creation
endef

define Package/viva/install
    $(CP) ./files/* $(1)/
endef

define Build/Compile
    true
endef

$(eval $(call BuildPackage,viva))
