What would be 'unusual or incorrect' in
$ cat hello.F
program hello
implicit none
write(*,*) 'Hello!'
end
(1)
$ g77 hello.F -o hello -L/usr/lib/gcc/i686-pc-cygwin/3.4.4 -lg2c
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o):(.text+0xab):
undefined reference to [EMAIL PROTECTED]'
collect2: ld returned 1 exit status

$ g77 hello.F -L/usr/lib/gcc/i686-pc-cygwin/3.4.4 -lg2c -o hello
$ ./hello
Hello!
?
It should all become clear in terms of the linker's requirement that
undefined references must always come in objects earlier than the
symbols that satisfy those references
I know this...but then '-o hello' contains symbols that satisfy previous
references ?
(compare (1) with (2))
I think you're speculating too much. What does it do without adding the
library and path in the first case? I'm not at a Windows box right now
but I get a similar link error from Linux in the first case. You'll
either see the same thing I do without the library (everything's fine)
or you'll see a different problem. If it's the former, your problem
is that you added the unneeded library. If it's the latter, it's an
ordering problem as Dave mentioned.
