[Users] Error about a shared object file

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.
