[Mingw-w64-public] newbie installation question

[K M <lon...@gm...>]

Hi,

I just downloaded the "Complete Root Environment Snapshot", specifically
mingw-w64-bin_x86_64-mingw32_20071203.tar.bz2, unpacked it, tried to compile
a hello program and failed.  The sourceforge page for the project does not
appear to have any starter guidelines, so I have some very basic questions.
Please indulge me.

1) If I have a plain, bare WinXP64 system, is this all I need?  Or are there
more packages that I need to download?

2) Is it sufficient to simply unpack the archive into any directory and add
%MYDIR%\root-x86_64-pc-mingw32\bin to the PATH variable?

What else needs to be done?  The steps above are essentially what I did.
When I try:

gcc hello.c -o hello.exe

I get:

e:/install/mingw/64b/root-x86_64-pc-mingw/bin/../lib/gcc/x86_64-pc-mingw32/4.3.0/../../../../x86_64-pc-mingw32/bin/ld.exe:
crt2.o: No such file: No such file or directory
collect2: ld returned 1 exit status

It appears to fail while trying to link the executable.  If I do:

gcc -c hello.c

This does successfully create a hello.o.  Using nm to check hello.o, I do
see a symbol defined for _main and an undefined symbol _puts (along with
some other things), so it appears to have made the object file.

Any help is appreciated.
