>Description:
Compiling/executing a FORTRAN program fails, with the following message displayed: "/usr/lib/libg2c.so: warning: tempnam() possibly used unsafely; consider using mkstemp()". I'm pretty sure that it is not a problem with my Fortran program (I started with one that is ridiculously simple and tried others) or OS or library modifications (see "how to repeat the problem").
p.s. sorry if this is not the right forum for this problem (I'm a newbie)-- please point me in the right direction if it is the wrong forum.
>How-To-Repeat:
Start with a fresh PC, nothing on the hard drive (i.e. no partitions). Install FreeBSD from the CD ROM using the X User distribution. Reboot from the hardrive, login, create the simplest FORTRAN program you can think of with the .f extension (I tried other extensions, and they producted the same problem), use f77 to compile/execute the program, and before you get any output from the program, the above error message appears. In short, the most vanilla version of FreeBSD will not let you use the Fortran compiler! (it is the single reason I purchased FreeBSD, for a Fortran compiler and UNIX based OS)
For example, I created nick.f with the following contents:
PROGRAM NICK
PRINT *, 'HELLO'
END
Then, from the command line I typed "f77 nick.f". Bingo, error message, and no "HELLO" on my screen.
