[RegCNET] Not obtaining the restart files.

[Sarin TS]

Hello Everyone,
Thank you all for your suggestions. I tried installing the model again and
found that the error came about due to line 922 of the mod_savefile.F90  in
the Main directory. I changed the line from :


*                         "ncstatus =
nf90_put_att(ncid,nf90_global,'idatex',toint10(idate))"  to *
*                          "ncstatus =
nf90_put_att(ncid,nf90_global,'idatex',int(toint10(idate),ik4))"*

and then followed the standard installation process i.e bootstrap >
configure > make and the make install. After this, the restart files were
successfully made. I hope this helps anyone who runs into a similar issue.
