Description matthew jull 2000-12-07 12:30:08 EST
i've got a g77 compiler problem that also occurs with a demo
version of a commercial f77 compiler (Absoft). Even using a very simple 
program such as test.f :


and compiling with f77  i get:

{menudo}/home/jull/toko/2por~> /usr/bin/f77 test.f
/usr/lib/gcc-lib/i386-redhat-linux/2.96/libg2c.a(open.o): In function
`f_open': open.o(.text+0x4e6): the use of `tempnam' is dangerous, better

       using f77 from a commercial Absoft demo compiler i get:

{menudo}/home/jull/toko/2por~> /usr/absoft/bin/f77 test.f
FORTRAN 77 Compiler 5.0, Copyright (c) 1987-2000, Absoft Corp.
This demonstration copy of Absoft Fortran 77 expires in 16 days.
/usr/absoft/lib/libfio.a(lowlevel.o): In function `_temp_file':
lowlevel.o(.text+0x10): the use of `tempnam' is dangerous, better use

the compiled program runs fine with either compiler, but i am
baffled why i should have this "warning" when compiling, other 
than to say that it looks like the compiler is using an older command 
(tempnam) to make a temporary file, while some
configuration files (or something) want it to use the more
up-to-date mkstemp command. 
Do you know how I could fix this problem? I use the fortran compiler
enough that it will be bothersome always having this message popping up and
I also wonder if it will have any impact on the numerical calculations
I am doing. My guess is that since it occurs with both compilers, it is not
compiler problem, but perhaps a library problem.


p.s. i have all recent updates/patches to redhat 7 as of dec.7/2000.
