添加自定义TinaSDK Package

在 Tina 里新增一个 Hello World 软件包，使用 Tina 编译 Hello World 并一同打包进入 Tina Linux。这个方法不但适用于 Hello World 程序，同样也适用于所以希望将自己的软件包整合进入 Tina Linux 的情况。通过这个方法，可以很方便的管理多库编译链接，解决编译链接的难题，也可以提供Tina Linux 的底层调用库函数的接口，免去单独交叉编译的麻烦。

创建Helloword Package

首先，在 Tina Linux SDK 的 openwrt/package 文件夹新建一个存放项目文件的 helloworld 文件夹，并准备外层 Makefile 和 src 文件夹，在 src 文件夹里建立一个编译使用的 Makefile，把源码放到 src 文件夹里目录结构如下：

首先编写外层 Makefile 供 Tina Linux 检索查找。需要注意的是 Makefile 有非常严格的缩进要求，直接复制代码的话，容易导致缩进混乱,编译报错。

include $(TOPDIR)/rules.mk
include $(BUILD_DIR)/package.mk

PKG_NAME:=helloworld
PKG_RELEASE:=1

PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME)
SRC_CODE_DIR := ./src/

define Package/$(PKG_NAME)
    SECTION:=hello
    CATEGORY:=Hello World
    TITLE:=hello world test
endef

define Package/$(PKG_NAME)/description
    Hello World
endef

define Build/Prepare
	mkdir -p $(PKG_BUILD_DIR)
	$(CP) -r ./src/*  $(PKG_BUILD_DIR)/
endef

define Build/Compile
	$(MAKE) -C $(PKG_BUILD_DIR)/ \
		ARCH="$(TARGET_ARCH)" \
		AR="$(TARGET_AR)" \
		CC="$(TARGET_CC)" \
		CFLAGS="$(TARGET_CFLAGS)" \
		LDFLAGS="$(TARGET_LDFLAGS)"
endef

define Package/helloworld/install
	$(INSTALL_DIR) $(1)/usr/bin
	$(INSTALL_BIN) $(PKG_BUILD_DIR)/helloworld $(1)/usr/bin/
endef

$(eval $(call BuildPackage,$(PKG_NAME)))

然后编写用于编译 helloworld 的 Makefile 需要注意的是 Makefile 有非常严格的缩进要求，直接复制代码的话，容易导致缩进混乱,编译报错。

main: main.o
	$(CC) $(LDFLAGS) main.o -o helloworld

main.o: main.c
	$(CC) $(CFLAGS) -c main.c

clean:
	rm *.o helloworld

和 main.c 的 helloworld 源码

#include <stdio.h>

int main(int argc, char const *argv[])
{
    printf("Hello World Tina Package!\r\n");
    return 0;
}

编写完成后，我们可以单独通过 mm 命令来单独编译验证。首先确保已经 source build/envsetup.sh 并已经 lunch 选择了单板，之后进入package/myapp/helloword 文件夹下执行命令 mm -B 其中-B 参数是先 clean 再编译，如果不加这个参数就是直接编译。

如下Logs为单独编译安装我们自定义 helloword软件包的log过程
