libtorrent, libtorrent-devel: there are no arguments to 'posix_memalign' that depend on a template parameter, so a declaration of 'posix_memalign' must be available

[gorzarg@…]

• OS: Mac OS 10.4.11
• Xcode: version 2.5

I was trying to upgrade rtorrent-devel, which needs libtorrent-devel (among other things). It fails in the build stage with the error:

Error: Target org.macports.build returned: shell command failed (see log for details)

Log file is attached.

The revelant error from the log seems to be:

I see you are trying to install this on an Intel Mac running Tiger. I suppose Tiger does not contain the posix_memalign function. I know Snow Leopard does.

​This Stack Overflow question suggests posix_memalign may not even be needed on the Mac (though Apple did add it to Mac OS X some time after Tiger, so it must serve some purpose...)

Looks like this has been known upstream for a while: ​http://libtorrent.rakshasa.no/ticket/2086

Especially since this appears not to be an issue in the latest version of Mac OS X, I don't plan to implement a fix in this port. Your best bet if you can't upgrade would be to get upstream to integrate the patches from the above ticket, or else apply them manually.

Replying to gardnermj@…:

So I used the patch you suggested for libtorrent-devel, but it didn't work either. (Log file is attached.) The thing is, the patch was for a previous version of libtorrent, not the one that just came out at the end of October, 2010, so that might be the reason why it fails also...
