Hi Jim,

 

Could you please run the command “lsb_release -d” in your Ubuntu terminal and reply with the output?

 

Also, could you please try searching for a “librtmp” package using the following command:

sudo apt search librtmp

 

For reference, I found a “librtmp1” package on my Ubuntu system (not in the Windows 10 Linux subsystem). Based on the name of the missing library file, I think you would need a “librtmp0” package on your system in order for that particular NCL binary release to work.

 

I suspect that Microsoft may have updated the version of Ubuntu used in the Windows 10 Linux subsystem environment, in which case the ncl_ncarg-6.4.0-Debian8.6_64bit_gnu492.tar.gz download might actually work better.

 

Thanks,

Kevin

Update: I now installed the csh and libssh2-1 packages and confirmed that csh functions. Then I emptied the ncl-6.4.0 directory using rm –r and reinstalled ncl_ncarg-6.4.0-Debian7.11_64bit_gnu472.tar.gzbut the ncl –V installation test still yields the same error:

“ncl: error while loading shared libraries: librtmp.so.0: cannot open shared object file: No such file or directory"

 

How can I fix this to get NCL to install?

 

Thanks.

Hi,

 

I attempted to install NCL today on a new Windows 10 computer by carefully following your instructions at:

 <http://www.ncl.ucar.edu/Download/windows_linux_subsystem.shtml> http://www.ncl.ucar.edu/Download/windows_linux_subsystem.shtml

 

I chose to install Ubuntu per the recommendation of the PC World article that you cited:

 <https://www.pcworld.com/article/3055403/windows/windows-10s-bash-shell-can-run-graphical-linux-applications-with-this-trick.htm> https://www.pcworld.com/article/3055403/windows/windows-10s-bash-shell-can-run-graphical-linux-applications-with-this-trick.htm

 

I chose not to install Xming, I chose to install ncl_ncarg-6.4.0-Debian7.11_64bit_gnu472.tar.gz, and used vim to edit my .profile file.

 

During the installation I received “Unable to locate package” errors for the csh and libssh2-1 packages.

 

In response to the ncl –V installation test I received the error:

“ncl: error while loading shared libraries: librtmp.so.0: cannot open shared object file: No such file or directory"

 

Then when I followed the troubleshooting recommendation to install the offending package I received the error message:

“E: Unable to locate package librtmp.so.0”

 

The attached file is copied directly from my Linux terminal window and contains the specific commands I issued along with the specific error responses.

 

Please let me know how I can remedy the above problems and install NCL.

 

Thanks.

 

Jim
