[tiandong19860806]

Hi all,

Do you have some problem about install the dragonfly-0.9.1 by source code building?

Below content, it's my installation of dragonfly-0.9.1.

I take many time, the last step （glibc-2.29 build install） is failed and difficulty.

Part I : enviroment as below:
(1.0) OS
OS : CentOS 7.9 x64
uname -a:
Linux CNT7XDFLY01 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

(1.1) reference software: automake
automake = 1.16.1
m4 = 1.4.18
autoconf = 2.69
gcc = 4.8.5-44.el7
gcc-c++ = 4.8.5-44.el7

(1.2) reference software: make
make = 4.2.1
libtool = 2.4.2-22.el7_3
gettext-devel = 0.19.8.1-3.el7

(1.3) reference software: gcc
gcc = 12.2.0
m4 = 1.4.18
gmp = 6.2.1
mpfr = 4.1.0
mpc = 1.2.1
isl = 0.24

(1.4) reference software: glibc
glibc = 2.29 ( ** install failed , many times always is failed ** )
cpp = 4.8.5-44.el7
binutils = 2.27-44.base.el7_9.1
python3 = 3.6.8-18.el7
bison = 3.0.4-2.el7

(1.5) Startup dragonfly or execute --help:
DragonFly : 0.9.1

Part II : installation happened problem.
(2.1) glibc-2.29 execute command 'make', happened error as below: step 4 install glibc
