Re: Problems with file permissions and cp when running on Vista

I'd start at the source.  Give yourself POSIX-style access to the files

ignored.  For whatever reason, it looks like your source file has no
POSIX permissions for user, group, and other.  Fix that with 'chmod'
and I think you'll have solved your problem.


I struggle to give myself posix style permissions. I have a file README.txt in the root of my build source tree: $ getfacl README.txt # file: README.txt # owner: Tom # group: None user::--- group::--- group:SYSTEM:rwx group:Administrators:rwx group:Users:r-x mask:rwx other:---

If I then do chmod --
$ chmod 755 README.txt
chmod: changing permissions of `README.txt': Permission denied

When I had that on Vista, I found running the Cygwin window as
administrator allowed me to chmod stuff.  I had to chmod the whole
of /usr to something more useful. [Just in case you need it: right
click the icon, then "run as administrator" is near the top of the
menu. BYKT, I expect]
