RE: copyfile() not working on my new Win7 PC

[Tatsuro MATSUOKA]

Hello


HMMM! Your windows 7 system seems to reject the Msys system shipped with the 
octave-3.2.3.   
Can you execute 'C:\Octave\3.2.3_gcc-4.4.0\MSYS\bin\sh' from your windows run 
or command prompt?

For Run Command for windows 7, please see 
http://www.nirmaltv.com/2009/01/15/enable-run-command-in-start-menu-in-windows-7/

If it cause the same error, the problem is on the Msys between and your window 
7.

If the direct execution of Msys sh.exe will give the similar failure, it is 
better to ask in the
MinGW-Msys mailing list, I think.
https://lists.sourceforge.net/lists/listinfo/mingw-msys

BTW, the Msys system have been entirely updated May 2010, which is after 
version 3.2.4 release. 
If you replace your Msys system in C:\Octave\3.2.3_gcc-4.4.0\MSYS to new 
version, it might be possible
to resolve the problem.

However the newest Msys lacks comprehensive installer. You have to download the 
a lot of necessary
components and  manually extract the archive file using the extracting which 
can treat lzma
compression.  It is not easy task for those who do not have enough knowledge on 
the Msys system.


Oh! I have just found in the Msys page
*********
 So, all the MSYS components are now available as separate downloads managed by 
mingw-get (currently
alpha release).
***********


I hope your problem will be solved.

Regards

Tatsuro
