The default uses the PKG_SOURCE_URL and the # PKG_SOURCE which is not defined here to download the source from the web. # In order to just build a simple program that we have just written, it is # much easier to do it this way. define Build/Prepare mkdir -p $(PKG_BUILD_DIR) $(CP) ./src/* $(PKG_BUILD_DIR)/ endef # We do not need to define Build/Configure or Build/Compile directives # The defaults are appropriate for compiling a simple program such as this one # Specify where and how to install the program. Since we only have one file, # the helloworld executable, install it by copying it to the /bin directory on # the router. The $(1) variable represents the root directory on the router running # OpenWrt. The $(INSTALL_DIR) variable contains a command to prepare the install # directory if it does not already exist. Likewise $(INSTALL_BIN) contains the # command to copy the binary file from its current location (in our case the build # directory) to the install directory. define Package/helloworld/install $(INSTALL_DIR) $(1)/bin $(INSTALL_BIN) $(PKG_BUILD_DIR)/helloworld $(1)/bin/ endef # This line executes the necessary commands to compile our program. # The above define directives specify all the information needed, but this # line calls BuildPackage which in turn actually uses this information to # build a package. $(eval $(call BuildPackage,$(PKG_NAME)))package/helloworld/src/helloworld.c 文件内容：

root@TinaLinux:/# helloworld Hell! O’ world, why won’t my code compile?烧到板子，执行 helloworld，完全OK
-
实际测试的时候， helloworld 文件夹可以埋多三层，make 还能找到，如果四层/五层以上就扫描不到不到了。
执行： mv package/helloworld package/test1/test2/test3/
重新 lunch
make package/helloworld/compile
或者：
make package/test1/test2/test3/helloworld/compile
均可以成功。

@tigger 在 给D1 SDK 添加一个简单的helloworld package 中说：
st1/test2/test3/helloworld/compile
递归多少层都可以，只要你source xxx 正确了
