newbie gfortran question

[Jeff Tibbitt]

Hi,

I recently downloaded the gfortran compiler for my new 
ibook with OSX 10.3.5

I tried compiling a simple fortran program named hello.f90



The command I issued was:

gfortran -o a.out hello.f90



The error I get is:

Claws-Computer:~/test/practice Claw$ gfortran -o a.out 
hello.f90
/usr/bin/ld: can't locate file for: -lcrt1.o
collect2: ld returned 1 exit status



When I compile using the -c flag to produce an object file, 
it works.  Then when I try to make the executable the same 
error happens.

Im pretty new at fortran and Mac, and could really use a 
suggestion.

Thanks,

Jeff
