Hi lework: I could not reproduce the issue. Here's what I did:

1. I rented a centos 7 droplet on digital ocean.

   CentOS Linux release 7.9.2009 (Core)

2. I installed git with yum install git
3. I installed gcc with yum install gcc-c++
4. I checkout the calculator project: git clone https://github.com/tmilev/calculator.git
5. I made the calculator: make -j2 nossl=1 noMongo=1
   (I used -j2 as I rented a very slow machine).

The calculator project appeared to build "as is".

Can you give me more information? Did you try pulling the latest version:

git pull ... ?

[lework]

I downloaded the master directly https://github.com/tmilev/calculator/archive/refs/heads/master.zip

[lework]

I used git clone to download and compile it successfully, thanks for your reply.

If you don't mind I will mark this as closed, let me know if the issue shows up again.

Many thanks for the feedback!
