Commenting the line with the patch file in Portfile produces something that seems to be usable…

[ryandesign (Ryan Carsten Schmidt)]

Your log shows an unclean build; it's not surprising therefore that the patch would fail to apply, since it had already been applied previously. Please clean, selfupdate, and try again.

[jeremyhu (Jeremy Huddleston Sequoia)]

This port has had a major update over the past 2 weeks. Please try the current port and report any errors.

This evening I really cleaned libunwind-headers! I have now a different problem:

and can't build libunwind-headers…

I'm confused. The problem you are reporting here is a build failure in ld64 because the libunwind-headers port is not installed. Why can't you install the libunwind-headers port? It has no dependency on ld64.

[jeremyhu (Jeremy Huddleston Sequoia)]

We can deal with that in your new ticket, #46547

It looks like your port tree is either corrupt or out of date.

[ballapete (Peter "Pete" Dyballa)]

Replying to jeremyhu@…:

I'm confused.

So am I! I explicitly asked port to 'buil libunwind-headers' and at least you can see msg:main ---> Computing dependencies for libunwind-headers:msg:main in main.log, but then port starts to build something completely different! Are now MS programmers writing on port?

Why can't you install the libunwind-headers port?

Because port is preventing me from doing so. I am really willing to build the libunwind-headers!

[ballapete (Peter "Pete" Dyballa)]

Replying to jeremyhu@…:

Why can't you install the libunwind-headers port?

It seems that I managed to install them! I remember vaguely that I patched Portfile to apply the one patch. When I now try to forcibly build libunwind-headers I can see:

DEBUG: No need to upgrade! libunwind-headers 35.3_0 >= libunwind-headers 35.3_0

and then port starts to build ld64…

There must be something not working correctly with svn by which I have to update Macports. Or I need to return to the normal setup of MacPorts and perform the (self)update with rsynch…

[jeremyhu (Jeremy Huddleston Sequoia)]

Yes, your ports checkout is corrupt our out of date. See #46547.

I switched back to the rsynch method. Libunwind-headers 3.5.0_7 built and installed without problem.
