Making rsync compile under Mac OS X 10.3.9 with extended attributes

[Vitorio Machado]

Sorry, I've misread your mail.

But don't give up, I think that if we correct the headers in 10.3, we  
have a chance to make it compile. We should look at the ACL and xattr  
code and see if there are only constant and variable definition on  
the system headers that are not found in 10.3 or if it's more deep  
lied to the 10.4 API. In this case it represents much more work, but  
we have the chance that the basic system layer (Darwin) of 10.4 is  
released open source... So maybe we could take some code from there  
to have our xattr on 10.3...

So, if nobody have a better idea, I think we should proceed like this:

1) Look on ACL and xattr code to understand what code they expect  
from the system

2a) If it's just a definition stuff (variable declaration, constants,  
etc) we can try a workaround of the configure script or something to  
put another header for 10.3 systems giving all those stuff that  
aren't built-in in the system headers. This shouldn't represent a lot  
of work

2b) If xattr and ACL code expect to use system fonctions, it won't be  
so simple... We can try patching the 10.3 system with some code of  
Darwin 8 (system code of 10.4 OS) hoping not have to go too deep, but  
just getting 1 or 2 files from it.

3) compile rsync with xattr support successfully with our little  
hacking.

I will start looking into the code to try to figure out xattr and acl  
dependencies on the system. But I don't have Mac OS 10.3 here, only  
10.4. It will be impossible for me to make any test today.

Chin up, we can do it!
