更新 gcc 后 bazel "undeclared inclusion(s)" 错误

Question

从 gcc-7.1 更新到 gcc-7.2 后，我收到很多关于未声明的标准库头文件包含的错误。例如

$ bazel build //test:my_test
ERROR: /home/haining/my_project/BUILD:39:1: undeclared inclusion(s) in rule '//test:my_test':
this rule is missing dependency declarations for the following files included by 'test/test_range.cpp':
  '/home/haining/gcc-7.2/include/c++/7.2.0/cstddef'
  '/home/haining/gcc-7.2/include/c++/7.2.0/x86_64-pc-linux-gnu/bits/c++config.h'

  '/home/haining/gcc-7.2/include/c++/7.2.0/new'
  '/home/haining/gcc-7.2/include/c++/7.2.0/exception'
... etc ...

我该如何解决这个问题

Answer 1

不确定这是否是正确的解决方案，但我可以通过使用

删除我的整个 bazel 缓存目录来实现它

$ rm -rf ~/.cache/bazel

我不确定这还有什么其他效果，可能还有更好的东西，我做的感觉就像一个大锤

Answer 2

每当您对系统执行 Bazel 不可能知道的操作时，运行 bazel clean --expunge 是个好主意。这只是一种更礼貌的方式 rm -rf ~/.cache/bazel :)
