OpenWRT 的简单 Hello World 程序
Simple Hello World program for OpenWRT
我正在尝试学习 OpenWRT。
我已经下载了sdk。
在 packages\helloworld 文件夹中创建了一个简单的 helloworld.cpp 文件
在 packages\helloworld
中创建了以下 Makefile
生成文件
include $(TOPDIR)/rules.mk
PKG_NAME:=helloworld
PKG_RELEASE:=1
PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME)
include $(INCLUDE_DIR)/package.mk
define Package/helloworld
SECTION:=utils
CATEGORY:=Utilities
TITLE:=Helloworld -- prints a snarky message
Package/PKG_NAME/description:=\
If you can't figure out what this program does, \\
you're probably brain-dead and need immediate \\
medical attention.
endef
define Build/Prepare
mkdir -p $(PKG_BUILD_DIR)
$(CP) ./src/* $(PKG_BUILD_DIR)/
endef
define Package/helloworld/install
$(INSTALL_DIR) $(1)/bin
$(INSTALL_BIN) $(PKG_BUILD_DIR)/helloworld $(1)/bin/
endef
$(eval $(call BuildPackage,helloworld))
之后我运行从sdk root
发出命令
我收到以下错误
