MacOS use the C language compiler is clang under llvm, all using gcc will be linked to the use of clang.
Such as checking gcc version
$ gcc -v Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1 Apple clang version 11.0.0 (clang-1100.0.33.8) Target: x86_64-apple-darwin19.0.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin
Display is clang version. Currently clang on my machine is 11.0.0
The reason for the above problem is to clang in the 8.0 version of the code requirements are more stringent, there is a special situation is judged to be wrong, it will not compile.
Error message in the shadow refers to a function defined within the parameters of variables and passed the same name, this is the case clang rejected.
Study hall to see the error message, you can see that these errors have occurred in rocksdb folder. So far, rocksdb do not want to change the meaning of the code, not because they can not be used.
Compile time can be tagged -Wno-error = Error contains specific information so that the force is not being given.
Change /rocksdb/CMakeLists.txt file, diff form (if it is CockroachDB project, in the folder / cockroach / c-deps / file):
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()
Modify / rocksdb / Makefile file:
ifndef DISABLE_WARNING_AS_ERROR - WARNING_FLAGS += -Werror + WARNING_FLAGS += # -Werror endif
