[shiponcs]

My system:

> lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.3 LTS
Release:	22.04
Codename:	jammy

> gcc --version
gcc (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0

Steps to reproduce
Build an example (logs_simple) by running the command from the root directory of the repo

> bazel build examples/logs_simple:example_logs_simple

What is the expected behavior?
It should build the example and generate the binary (example_logs_simple).

What is the actual behavior?
The build fails as follows:

Could you please try bazel build --host_cxxopt=-std=c++14 --cxxopt=-std=c++14 examples/logs_simple:example_logs_simple ?

@owent thanks. This hack worked.

@marcalff Thanks. Seems like it doesn't support C++12 either.
