-有小伙子反映说 15.05.1 编译不了。其实是可以的。方法如下：
+在老旧版本（15.05）上编译时，尝试用 Makefile.cc 替换 Makefile。方法如下：
 
-* 删除或者注释掉 `include/package.mk` 的下面几行：
-
-  ```makefile
-  ifdef DESCRIPTION
-  $$(error DESCRIPTION:= is obsolete, use Package/PKG_NAME/description)
-  endif
-  ```
-
-* 然后使用下面的命令编译（不要照搬哦，根据自己情况修改）：
-
-  ```bash
-  ln -s ../feeds/base/package/utils package/utils
-  make defconfig
-  git clone git@github.com:CHN-beta/xmurp-ua.git package/xmurp-ua
-  make package/xmurp-ua/compile V=sc ARCH=mips
-  # 这里会报错，没关系
-  cp -r package/xmurp-ua build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic
-  make package/xmurp-ua/compile V=sc ARCH=mips
-  ```
+```bash
+git clone git@github.com:CHN-beta/xmurp-ua.git package/xmurp-ua
+cp package/xmurp-ua/Makefile.cc package/xmurp-ua/Makefile
+ln -s ../feeds/base/package/utils package/utils
+make defconfig
+make package/xmurp-ua/compile V=sc ARCH=mips
+```
