sh file to compile cpp functions on Mobaxterm with windows machine

Question

YOUR HELP PLEASE!

I need to run an sh file that calls cpp functions on Mobaxterm with windows machine, I am a newbie in shell scripting, and I cant understand the following error messages :

Creating rtlib.a...
ar: unknown option -- u
BusyBox v1.22.1 (2015-11-10 11:07:12    ) multi-call binary.

Usage: ar [-o] [-v] [-p] [-t] [-x] ARCHIVE FILES

Extract or list FILES from an ar archive

        -o      Preserve original dates
        -p      Extract to stdout
        -t      List
        -x      Extract
        -v      Verbose

Makefile:55: recipe for target 'rtlib.a' failed

I'm sorry for pasting this too long code but I'm really facing problems and can't understand. So any help will be appreciated!

What do you mean by _calling a cpp function_ from a Terminal? You can invoke a C++ function only from within the C++ program which contains the function. — user1934428, Jul 14 '20 at 10:44
Thank you for having time to reply, what I meant is that the sh file will call a cpp functions in the same directory like generateGetStream() , generateRTRo(), generatertlib() — Marven, Jul 14 '20 at 11:10
I don't know that really, but the software package provided by to me as student, contains sh and cpp files. And actually the sh file call the cpp files and I think it works for others ! — Marven, Jul 14 '20 at 11:25

The makefile in the subdirectory rtlib uses a rule (explicit or implicit) to make rtlib.a with the ar command option u which the BusyBox ar doesn't know. Cure: Use another shell and a full-fledged toolchain. (You may be able to install the popular Cygwin toolchain with the MobaXterm packages manager tool.)

Thank you for the reply, as I mentionned I'm newbie in this kind of coding , would you explain step by step, word for word to have a clear vision ? – Marven Jul 14 '20 at 09:53
I did installed the Cygwin toolchain (64), but when running I got the same error message ! Please is there any other suggestions ? – Marven Jul 14 '20 at 10:22
The question is now: Why is BusyBox used rather than an other shell? - I'd uninstall the "busybox" package (and open a new terminal tab). – Armali Jul 14 '20 at 11:25
Would you please explain more, step by step ? – Marven Jul 14 '20 at 21:00
In the MobaXterm window (at least in mine) there's a sidebar with tabs Macros, Tools, Sessions. Click on Tools. Now there's a menu with sections Terminal Games, System, Office, Network. Under System, there's MobApt packages manager; click there. After a while, a window with the list of packages appears. Select busybox and busybox-standalone; click Uninstall. – Armali Jul 15 '20 at 06:30
I have uninstalled the busybox and the busybox stand-alone, and I restart my desktop, but the same problem persist, always said : ar: unknown option -- u – Marven Jul 15 '20 at 14:14
Is there still the line `BusyBox v1.22.1 (2015-11-10 11:07:12 ) multi-call binary.` in the error message? If so, the question is: Where is this Busybox, since you uninstalled already. You might try `which busybox` or `which ar` to find it. – Armali Jul 21 '20 at 05:05
