Sorry, I don't know how to create a module from source files like
this, BUT I now know how to combine object files and assemble them
into a library.
For example:
C:\Users\epc\temp>type main.f90
k = 1
print *, k
call sub1(k)
print *, k
end
C:\Users\epc\temp>type *.f
sub1.f
c234567
subroutine sub1(i)
call sub2(i)
return
end
sub2.f
c234567
subroutine sub2(i)
i = i + 1
return
end
C:\Users\epc\temp>g95 -c *.f [compile only, create .o = object
files]
C:\Users\epc\temp>ar rvs mylib.a *.o [create a library, r=replace
existing, v=verbose list, s=include symbols index]
ar: creating mylib.a
a - sub1.o
a - sub2.o
C:\Users\epc\temp>g95 main.f90 mylib.a -o myprog.exe [compile and
then link including the new library.]
C:\Users\epc\temp>myprog

At least now I CAN build something larger than a breadbox!
