开放式WRT Makefile 目标模式不包含“%”

如何解决开放式WRT Makefile 目标模式不包含“%”

我正在尝试编译 OpenWRT 包。已经编译工具链。从 here 我知道使用静态模式规则时可以，但我没有。我检查了整个文件是否有语法错误 - 一切正常（也许我错过了一些东西）。

操作系统：Ubuntu 20.04 服务器
g++：9.3.0
OpenWRT：19.07.7

wiha@osBoxes:~/source$ ./scripts/Feeds update mypackage
Updating Feed 'mypackage' from '\home\wiha\package_src\package' ...
Create index file './Feeds/mypackage.index' 
/home/wiha/source/Feeds/mypackage.tmp/info/.files-packageinfo.mk:1: *** target pattern contains no '%'.  Stop.

生成文件：
