Build mix from source hit 'GLIBC_2.18' not found in envoy

[dove-young]

Describe the bug

Build mix found error /root/go/out/linux_amd64/release/envoy: /lib64/libc.so.6: version 'GLIBC_2.18' not found (required by /root/go/out/linux_amd64/release/envoy)

Run envoy manually also trigger this error.

[root@advise1 istio]# /root/go/out/linux_amd64/release/envoy
/root/go/out/linux_amd64/release/envoy: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /root/go/out/linux_amd64/release/envoy)
[root@advise1 istio]#

Build glibc-2.18 and install it to /opt/glibc-2.18, then run envoy again.

[root@advise1 istio]# LD_LIBRARY_PATH=/opt/glibc-2.18/lib /root/go/out/linux_amd64/release/envoy --help
Segmentation fault
[root@advise1 istio]# LD_PRELOAD=/opt/glibc-2.18/lib/libc-2.18.so; /root/go/out/linux_amd64/release/envoy --help
/root/go/out/linux_amd64/release/envoy: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /root/go/out/linux_amd64/release/envoy)

Expected behavior

Build instruction would mention that this does not work in CentOS 7.x.

And it would be better to fetch an envoy binary which works in CentOS 7.x in Istio`s Makefile

GLIBC includes in CentOS 7 is 2.17
Steps to reproduce the bug

Build mix in CentOS 7.x

cd /root/go/src/istio.io/istio
make

Version

Master code at commit b76a5a8

Installation
Not installed. Just build.

Environment

CentOS 7

[dove-young]

There is a way to fix it.

• Let user to build a separate glibc-2.18 in CentOS

wget http://ftp.gnu.org/gnu/glibc/glibc-2.18.tar.gz
tar zxvf glibc-2.18.tar.gz
cd glibc-2.18
mkdir build
cd build
../configure --prefix=/opt/glibc-2.18
make -j4
make install

• Specify customized glibc-2.18 path to environment variable GLIBC_PATH
  • export GLIBC_PATH=/opt/glibc-2.18/lib
• Modify mixer/test/client/env/envoy.go to accept environment variable GLIBC_PATH
• Then build will go smoothly
