Problem compiling fortran90 source on itanium machine

[Rene_17]

On the Pa-Risc machines the source is compiled well, but on the itanium machine the source is compiled with error !

[iff4:]/root# f90 header.f
header.f
program HEADER

33 Lines Compiled
ld: Unsatisfied symbol "gethostname_" in file header.o
1 errors.

I don´t know why the system call is not working on the itanium machines ?

gethostname() is actually a C routine in
libc. You have to follow the rules for
C<->Fortran linking. Specifically, Fortran
compilers often add underscores to routine
names. You can tell f90 to not add the
underscore by using the +noppu flag.

The reason the behavior is different is
that on PA-RISC 32-bit the default is
"f90 +noppu", while on PA-RISC 64-bit
and on Itanium the default is "f90 +ppu".

In Fortran you should probably use HOSTNM()
anyway. HOSTNM() is a native Fortran routine. (However it's in libU77, so
use "f90 +U77" to access it.)

Hi Rene,

try to use +noppu option to the f90 compiler on the Itanium machine.
