How to install 3DNA on MinGW/MSYS

(1/6) > >>

happytreat14:
I'm installing x3DNA on a Windows OS. I have downloaded Ruby as well as MingW/MSYS systems.

However, when I typed find_pair -h into the terminal I got the following error:

--- Code: ---C:\Users\Downloads\x3dna-v2.3-mingw-win.tar\x3dna-v2.3\bin>find_pair -h
Please set the X3DNA environment variable
Run 'x3dna_setup', and visit http://x3dna.org/ for more info.

C:\Users\Downloads\x3dna-v2.3-mingw-win.tar\x3dna-v2.3\bin>x3dna_setup
'x3dna_setup' is not recognized as an internal or external command,
operable program or batch file.
--- End code ---

What should I do to resolve this?

xiangjun:
Thanks for using 3DNA.

As shown in the following screenshot, I can reproduce your problem on my Windows 7 system.


You are using Windows native command line shell (cmd) instead of the desired MSYS shell. Did you see the 'M' icon (for MSYS) on your desktop?

Hello Sir,
I am trying to install the program, but i am getting this error. The file x3dna_setup exists in the bin folder. I installed Rubby 2.2.5.
Thanks a lot in advance.

xiangjun:
Click on the Msys2 icon, in the terminal that appears, run the following two commands and report back what you get:


--- Code: ---pwd
    # in my case: /home/xiangjun
ruby -v
    # in my case: ruby 2.2.4p230 (2015-12-16 revision 53155) [x64-mingw32]

--- End code ---

Thanks,

Xiang-Jun


zainab fadhil:
