我已经在Omnet ++上构建了许多使用Veins的项目，在这个阶段没有出现任何问题，我决定在模拟中实现CAM消息。但是，在构建时，我遇到了以下错误：
12：41：23项目v2x配置发布的增量构建
make MODE =全部释放
cd源代码&&制造制造[1]：进入目录"/home/静脉/工作区. omnetpp/v2x/src "

错误2 "make MODE = release all"以退出代码2终止。
生成可能不完整。
12：41：24生成失败。3个错误，0个警告。（耗时549毫秒）
我的Makefile如下：

clang-release/src/v2x是一个目录，这是正确的，但它一直是这样的（甚至在最近的更改之前），它没有产生这个错误。
除了MakeFile错误之外，项目的任何脚本中均没有其他错误。
