envoy build in ubuntu and need some help

[RuijingGuo]

I failed to build envoy in ubuntu:

1. ubuntu 18.04
   a) container build: ./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.release'
   still in trying

   b) bare metal build: bazel build //source/exe:envoy-static
   Hit issue Envoy failed on Bazel CI with "unused variable 'factory_name'" #13079

2. ubuntu 20.04

   a) container build: ./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.release'

FAILED: Build did NOT complete successfully (894 packages loaded, 25584 targets configured)
ERROR: Couldn't start the build. Unable to run tests
FAILED: Build did NOT complete successfully (894 packages loaded, 25584 targets configured)
./ci/do_ci.sh: line 49: pushd: bazel-testlogs: No such file or directory

b) bare metal build: bazel build  //source/exe:envoy-static

I need to remove some compiler option to build out envoy:

my questions: what approach is right to build envoy in ubuntu? OS? build command?
I use gcc. how can I change to clang?

[dio]

@dio Have you tried to build it with ubuntu 20.04 with clang ? Appreciate if you could provide some steps to build envoy with clang. I tried with gcc and the build fails due to a known issue that hasn't fixed so far i guess.
