help install gfortran on Mac OS X version 10.5.6

[jon]

Mac with macosx 10.5.6 Build 9G55 (gfortran version stuff below).
Gfortran will not compile any code. I'm at a dead end trying to figure
this out. Any help would be greatly appreciated.

I downloaded and installed gfortran from (and as instructed on)
http://gcc.gnu.org/wiki/GFortranBinaries#MacOS.

I tried to compile a short program:

program test1
implicit none
character(len=*), parameter :: HELLO = " Hello, World!"
integer :: i
do i=1,22
write(unit=*,fmt=*) HELLO
end do
stop
end program test

bash-3.2$ gfortran -v -Wall test1.f95

Try compiling with:

gfortran -o test -Wall test.f95

that is, leave out the -v. I believe -v is used on its own to give
version information. I also put six spaces at the beginning of each
line (old fortran code style). There is probably a flag that lets you
leave out the spaces.

I hope this helps.

OK, using the .f95 extension means you don't need the spaces at the
beginning of each line.

Well, I put the -v in to let us see the version number. But with the
above suggestion, no output named test is produced: (hmm, does the
fact that the last line of the program does not terminate with a
newline be the cause of the problem?)

bash-3.2$ ls
hw.f90 hw.o hw.s mpiSim
project1 test1.f95
bash-3.2$ cat test1.f95

program test1
implicit none
character(len=*), parameter :: HELLO = " Hello, World!"
integer :: i
do i=1,22
write(unit=*,fmt=*) HELLO
end do
stop

end program test1bash-3.2$
bash-3.2$ gfortran -o test -Wall test1.f95

/usr/bin/ld: warning unknown -macosx_version_min parameter value:

I wondered:

(hmm, does the fact that the last line of the program does not
terminate with a newline be the cause of the problem?)

and apparently it does not. I added the newline and still no joy:

bash-3.2$ cat test1.f95
program test1
implicit none
character(len=*), parameter :: HELLO = " Hello, World!"
integer :: i
do i=1,22
write(unit=*,fmt=*) HELLO
end do
stop
end program test1

bash-3.2$ gfortran -o test -Wall test1.f95
/usr/bin/ld: warning unknown -macosx_version_min parameter value:
10.5.7 ignored (using 10.4)
/usr/bin/ld: /usr/lib/libSystem.dylib unknown flags (type) of section

/usr/bin/ld: /usr/lib/libSystem.B.dylib unknown flags (type) of
section 6 (__TEXT,__literal16) in load command 0
collect2: ld returned 1 exit status
bash-3.2$ ls
hw.f90 hw.o hw.s mpiSim
project1 test1.f95
bash-3.2$

I see that the os version number parameter is ignored and tries to use
10.4 which I don't have.

What are the next two lines referring to? I don't have the
familiarity with gcc or gfortran to understand this. I'm hoping it
could give someone a hint about what the problem is. But I'm a humble
programmer and even with my 44 years experience those lines leave me
clueless (not unusual some would say ;^).

Thanks to anyone who can help.

The newline can help at times. I've found issues with data files with
missing ending newlines...

However, I've just tried your program again and I'm getting an error:

gfortran: error trying to exec 'as': execvp: No such file or directory

I'm sure I got your program to compile before using the same compiler
version but it may have been on my home computer. I downloaded the
compiler from:

http://quatramaran.ens.fr/~coudert/gfortran/gfortran-macosx-x86.dmg

from http://gcc.gnu.org/wiki/GFortranBinaries

again and got the same error, no as??

No help yet.

gfortran -v

P.S. I'm using tcsh but bash didn't seem to help.

[db]

OK, it works at home. I may have an old installation on XCode at work.

Do you have the latest gcc?

Hmm. Nor sure. I dl'd and installed the gfortran. Do I need to
install more than what was provided by gfortran? If so, it would help
to have some documentation, somewhere, that would attend to this.

Any help is appreciated.

On the Mac the gfortran install assumes gcc or XCode (including gcc)
is already installed.

I think XCode is an optional install. Check your install disk/dvd. You
can join as a developer, there is a free level of membership that
gives you access to more up to date versions of XCode but the one on
the install disk should be enough.

Check to see if you have a /Developer directory. XCode is in /
Developer/Applications

Thank you Thank you for the help. I had installed XCode for Tiger.
When I upgraded to Leopard, that got cleaned out. I am installing it
now and hope this resolves the problem.

That indeed was it. Now gfortran works again!

Thank you again.
