Dear all

I am Hiromitsu Kigure.

This is the first time I send 

an e-mail to this mailing list.

I am sending you this email to seek your advice.

I use Einstein Toolkit in the 

following situation.

・OS:Fedora23

・Executable:etilgrmhd (IllinoisGRMHD)

The compile was done and 

executable file was made.

However the following error 

message was displayed 

when execute the file.

"error while loading shared libraries: libgsl.so.19: cannot open shared object file: No such file or directory"

There was no problem few weeks ago. 

So I don't have any idea why 

the error occured.

What should I do?

・Update the OS?

・Update the IllinoisGRMHD?

(I don't use the latest version)

I would appreciate it if you would give me some advice.

Thank you,

Best regards.
