Noted, thanks for the feedback
As per the product specifications I have to specifically work for MongoDB 3.6.9 version and there is no plan for updates in near future so I’ll have to stick to it only.
OS Distro and Version → Centos 7
[root@portal4 mongo-r3.6.9]# uname -a Linux portal4 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Not sure, no other process was running on machine while compiling the code. The VM was dedicated for compilation purpose only
[root@portal4 mongo-r3.6.9]# free -m

This was the error:
[root@portal4 mongo-r3.6.9]# python buildscripts/scons.py all --disable-warnings-as-errors
scons: Reading SConscript files ...
Invalid MONGO_VERSION '', or could not derive from version.json or git metadata. Please add a conforming MONGO_VERSION=x.y.z[-extra] as an argument to SCons

I had tried below command which resulted in unknown variable message MONGO_GITHASH but instead of removing MONGO_GITHASH from command line I added version.json
[root@portal4 mongo-r3.6.9]# python buildscripts/scons.py MONGO_VERSION=3.6.9 MONGO_GITHASH=none all
scons: Reading SConscript files ...
Mkdir("build/scons")
scons version: 2.5.0
python version: 2 7 5 'final' 0
Unknown variables specified: MONGO_GITHASH
Also git describe was not going to return any output as I had downloaded the code instead of cloning it. So opted for version.json workaround.
If I don’t add PATH in SConstruct file I get below error:
[root@portal4 mongo-r3.6.9]# python buildscripts/scons.py all
scons: Reading SConscript files ...
scons version: 2.5.0

See /root/mongoCompilation_TagCode/mongo-r3.6.9/build/scons/config.log for details
So i had to include the PATH variable to SConstruct file
I hope I have answered the required questions, let me know if you need further information.
Thanks in advance!
