编译 syzkaller 模糊器失败，没有任何错误或警告

Question

我在编译syzkaller时遇到问题（定制版本的syzkaller，基于syzkaller提交a371c43c33b6f901421f93b655442363c072d251，在此提交上编译成功）。

使用 make fuzzer 时，我收到一条消息说

build constraints exclude all Go files in xxx

由于我的环境是amd64和Linux，所以我认为这是正常的；但是编译失败。

我尝试使用-x和-v来显示编译日志，但是-v没有产生任何输出，并且-x生成的文件/tmp/go-xxxxx是空的。

这是编译命令：

我想知道为什么编译失败，因为它没有显示任何错误或警告。有没有办法让Go显示这些信息？

我尝试使用-x和-v来显示编译日志，但是-v没有产生任何输出，并且-x生成的文件/tmp/go-xxxxx是空的。

这是完整的输出：

我刚刚通过注释掉一些代码解决了这个问题，但我仍然不知道为什么会出现这个问题或为什么它得到解决。
