[嵌入式]【嵌入式开发基础】在mtk8516平台，使用ninja gn进行蓝牙模块编译时报错！

mtk8516平台基于yocto的系统构建，在对于bluetooth部分，Makefile的生成和构建是基于ninja、gn
在我的平台中遇到如下报错，

基于以上报错信息可以看到: cannot find -l-lpthread 导致的error，这里会很奇怪？？ 为什么会出现-l-lpthread?
通过测试于分析发现，是ninja 的版本 过高导致的问题, 也就是不同版本的ninja对应的语法是有差异的！！
知道了这一点后，找到了能编译过的电脑将对应的ninja和gn命令拷贝的本机中，然后重新编译工程！
