c - OpenWrt Makefile 包含 package.mk 错误

问题描述

我是 OpenWrt 和 Makefiles 的初学者，试图演示创建包的“Helloworld”示例，但在包提要更新步骤，从命令./scripts/feeds update mypackages我得到这个错误

Updating feed 'mypackages' from '/home/onur/Desktop/OpenWRT/openwrt/mypackages' ...
Create index file './feeds/mypackages.index' 
/home/onur/Desktop/OpenWRT/openwrt/feeds/mypackages.tmp/info/.files-packageinfo.mk:1: *** target pattern contains no '%'.  Stop.

我src-link mypackages /home/onur/Desktop/OpenWRT/openwrt/mypackages在我的 feeds.conf 目录中编译了“helloworld”C 程序/openwrt/helloworld，下面是我的 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/onur/Desktop/OpenWRT/openwrt/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
    $(MAKE) -C $(PKG_BUILD_DIR) \
    CXX="$(TARGET_CROSS)g++"
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))

我知道我在交叉编译部分可能有错误，但我认为这不是我现在遇到的问题。

当我尝试制作这个 Makefile 时，我得到了那个错误。

Makefile:13: /package.mk: No such file or directory
make: *** No rule to make target '/package.mk'.  Stop.

我在任何地方都找不到这样的问题。为什么它甚至找不到“package.mk”文件。我的目录结构是这样的，顶级目录是Desktop/OpenWrt/openwrt，这个 Makefile 在Desktop/OpenWrt/openwrt/mypackage文件夹中。我在 Ubuntu 20.04

我在 OpenWrt 论坛上找到了我的问题的解决方案。这是线程的链接
