[mpich-discuss] Mpich won't compile with gcc-5

[Balaji, Pavan]

Did you check if gfortran-5 works for simple Fortran programs?  It looks like it doesn't.

configure:38446: ./conftest
./conftest: error while loading shared libraries: libquadmath.so.0: cannot open shared object file: No such file or directory
configure:38446: $? = 127
configure: program exited with status 127
configure: failed program was:
| 
| 
|             program main
|             real a(2)
|             integer irc, cisize
|             irc = cisize(a(1),a(2))
|             end
