[grpc-io] Re: How to build a clang memory sanitizer instrumented version of gRPC?

[Mark Andrews]

The issue I run into is some sort of versioning problem:

$ clang --version
clang version 9.0.0-2~ubuntu18.04.2 (tags/RELEASE_900/final)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin


but running make on the Makefile with `CONFIG=msan` fails during probobuf 
build with:

checking zlib version... ok (1.2.0.4 or later)
checking for library containing zlibVersion... no
checking whether clang++ supports C++11 features by default... no
checking whether clang++ supports C++11 features with -std=c++11... no
checking whether clang++ supports C++11 features with +std=c++11... no
checking whether clang++ supports C++11 features with -h std=c++11... no
checking whether clang++ supports C++11 features with -std=c++0x... no
checking whether clang++ supports C++11 features with +std=c++0x... no
checking whether clang++ supports C++11 features with -h std=c++0x... no
configure: error: *** A compiler with support for C++11 language features 
is required.
Makefile:794: recipe for target 
'/var/dev/github/grpc/libs/msan/protobuf/libprotobuf.a' failed
make: *** [/var/dev/github/grpc/libs/msan/protobuf/libprotobuf.a] Error 1

searching around brought up some old posts that might be related, e.g.:

['yas...@google.com' via grpc.io]

Our current test infrastructure uses bazel for msan tests but earlier we 
were using Makefile with `CONFIG=msan` which is why I'm surprised that it 
did not work for you.
