[gradsusr] 回复： OpenGrADS 2.2.1 for Windows: Available for Testing

[weather.man]

Hi  Arlindo da Silva

I installed on my GrADS Dell XPS15, but it does not run correctly.Xming not start properly. My computer system is win10 64 bit . I  installed it on my other laptop with the same operating system,and It works fine. Very strange !

I think it is a problem with environmental variables. But I do not know how to do.

主　题：[gradsusr] OpenGrADS 2.2.1 for Windows: Available for Testing

Dear GrADS Users,

  After a long hiatus, I am pleased to announce a new OpenGrADS 2.2.1 build for Windows:


Windows: https://sourceforge.net/projects/opengrads/files/grads2/2.2.1.oga.1/Windows/

As usual, the superpack.exe is the familiar self-installing package (batteries included.)  The tar.gz file is intented for cygwin users (32-bit). As of now, I have no plans for a 64-bit cygwin build.  The main reason is the Windows Subsystem for Linux (WSL) capability that allows you to run the 64-bit Linux build under Windows 10. Read on.

Running GrADS under the Windows 10 Subsystem for Linux (WSL)

The OpenGrADS Linux tarballs should run out of the box on WSL. Here is a quick roadmap:

1) Install the Windows Subsystem for Linux:


WSL:  https://docs.microsoft.com/en-us/windows/wsl/install-win10
2) Install a Linux Distribution from the Microsoft App Store. The suggested Linux Distribution for GrADS is Ubuntu 18LTS although others may work as well.

3) Install an X server of your choice. The free Xming works great:


Xming: https://sourceforge.net/projects/xming/
Start the Xserver by clicking on it.

4) Download the OpenGrADS Bundle Linux tarball for glibc 2.17 (others may work, but the 2.17 is recommended for Ubuntu 18LTS):


Linux: https://sourceforge.net/projects/opengrads/files/grads2/2.2.1.oga.1/Linux/

5) On the Linux command line under Windows 10 do as you would do on regular Linux:

     % tar xvfz /path/to/opengrads-2.2.1.oga.1-bundle-x86_64-pc-linux-gnu-glibc_2.17.tar.gz
     % cd opengrads-2.2.1/Contents
     % ./opengrads  
      % ./grads
      % ./ncep

If you download the OpenGrADS on the Windows side, the tar ball will likely be on your Download folder. In this case, the /path/to above should be /mnt/c/Users/USERNAME/Downloads, where USERNAME is your user name.

Put the opengrads-2.2.1/Contents directory on your path and you are ready to go --- no need to set any environment variable other than PATH. It should work out of the box, YMMV.
Which version is faster? Cygwin-based or Linux under WSL?

I was hoping that the user community could help us answering this question. If you benchmark these 2 builds, please share your experience in this form:


Benchmark: https://goo.gl/forms/yUIEL8pncfGH87Zz1
I will share the results here.
    Please  report any issues with the Windows build by replying to this list. (No personal e-mail, please. I mean it.)
    Enjoy!
          Arlindo
