libffi @3.4.2_0 update caused some kind of mixup during rev-upgrade in Leopard PPC that results in a clear path not being followed NYD

But when I try to rebuild my version of GNU Emacs with GCC7 I get in configure.log:

dyld: Library not loaded: /opt/local/lib/libffi.7.dylib
  Referenced from: /opt/local/lib/libgobject-2.0.0.dylib
  Reason: image not found

I've also seen ld-127 form port ld64-127 crashing, see attached screenshot.

port itself has no proper plan to rebuild these invalid packages, it starts with guile (possibly trying to upgrade to new version 2.2.7_1 and never manages to finish (with "never" I mean a time period of three hours CPU use in top).

rev-upgrade is meant to take care of all this, but it's possible something was missed for a revbump or otherwise things got confused.

First think I would do is clean out all partially-built software. I often go into the main MacPorts build directory and see what's there, and clean it up manually, but sudo port -v reclaim has an option to do that as part of it's cleanup (be careful about deleting anything you want in your installed ports if you do that!).

libffi is very core, and as you have seen, lots of things break when it updates.

Looks to me like the first thing that needs to be working is llvm-3.4, so your linker works again. I would do that first, therefore:

sudo port -f uninstall llvm-3.4
sudo port -v install llvm-3.4

Then I would probably run sudo port -v rev-upgrade again, and let MacPorts sort the rest out. Looks like lots of things need to be rebuilt for the new libffi, no surprise as you have lots of things installed.

If you get the exact same error about libgobject-2.0.0.dylib being broken, and MacPorts has not sorted it out properly for some reason, then this is the port that would need to be uninstalled and reinstalled to fix that:

% port provides /opt/local/lib/libgobject-2.0.0.dylib
/opt/local/lib/libgobject-2.0.0.dylib is provided by: glib2

If you have a problem after doing the above, please post again.

Replying to kencu:

sudo port -f uninstall llvm-3.4
sudo port -v install llvm-3.4

I want GNU Emacs to work again (building it with GCC7). In it port might compile for days and weeks…

[kencu (Ken)]

Hah, new problem then.

Now how on earth does it happen that icu is trying to use /usr/lib/libstdc++.6.dylib on your system? I have no idea. That will never work.

So unless you know some secret thing you did, you will have to uninstall and reinstall icu.

This of course has nothing to do with libffi, so your rabbit hole just keeps getting deeper and deeper.

Hmmmm, rereading the comments on this ticket, this sounds like more of an issue with libc++. Reopening, as the libffi fix won't cure this one.

[kencu (Ken)]

we won't be making any more progress here. Please reopen with new information if this is still an issue for youl
