clang8.0及以上编译rocks问题
升级了MacOS 10.15 Beta版，结果编译 CockroachDB 遇到了问题。

MacOS 使用的 C 语言编译器是 llvm 下的 clang，所有的 gcc 的使用都会被链接到 clang 的使用上。
比如检查 gcc 版本
$ gcc -v
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.
Apple clang version 11.0. (clang-1100.0.33.8)
Target: x86_64-apple-darwin19.0.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
显示的就是 clang 的版本了。目前我的机器上的 clang 是 11.0.0
出现上面问题的原因是 clang 在8.0版本后对于代码的要求更为严格，有一种特殊的情况被判定为错误，无法正常编译。
报错信息中的 shadow 指的是函数内定义了和传入参数同名的变量，这就是 clang 拒绝的情况。
仔细看报错信息，可以看到这些错误都发生在 rocksdb 文件夹下。到目前为止，rocksdb 都没有要改一下代码的意思，因为又不是不能用。
编译的时候可以加上标签 -Wno-error= 让包含特定信息的错误强行不报错。
更改 /rocksdb/CMakeLists.txt 文件，diff 形式（如果是 CockroachDB 的工程，该文件在 /cockroach/c-deps/ 文件夹下）：
option(FAIL_ON_WARNINGS "Treat compile warnings as errors" ON)
if(FAIL_ON_WARNINGS)
if(MSVC)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /WX")
else() # assume GCC
- set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Werror")
+ set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-error")
endif()
endif()
修改 /rocksdb/Makefile 文件：
ifndef DISABLE_WARNING_AS_ERROR
- WARNING_FLAGS += -Werror
+ WARNING_FLAGS += # -Werror
endif
