Re: cl.exe compiles libraries with blank permissions

Further research shows that the issue is that the file is first created
additional windows permissions i.e. doing ls -lrt on the file gives:

The '+' indicating additional permissions.

The file is then copied to a separate directory and the additional
permissions are lost, so now doing an ls -lrt gives:
---------- 1 myname            Domain Users 14436 Jul  8 13:04 mylib.lib

The '+' is gone.  So does anyone know why the file permissions get
when the file is copied?
I suspect you're using 'cp' which by default only respects POSIX
permissions.  Use the '--preserve=all' switch in this case.

Thanks Larry, that explains the copying issue. I'm not sure what causes the POSIX permissions to be removed by the compiler though.

While it is a bit strange that a non-Cygwin program would create files with permissions that are completely untranslatable into some kind of POSIX permissions, it is possible. Non-Cygwin programs, of course, don't have to worry about supporting POSIX permission guidelines.
