lftp @4.9.1: Undefined CoreFoundation symbols

[cocobende]

Hello.

lftp port build fails on macOS Mojave 10.14.6. Here is the output of the port command:

$ sudo port install lftp

Always reproducible, tried to uninstall and clean port, to not avail.

The abovementioned log file is attached to this ticket.

I'll have a look on my non-default build machine. I still use Xcode 10.3 under Mojave, as I still consider Xcode 11.x broken.

[Schamschula (Marius Schamschula)]

I cannot reproduce this issue on my Mojave machine with Xcode 11.3.1.

Thank you very much for your feedback. I'll reinstall from scratch MacPorts and see if I can reproduce the problem on my side with a fresh install.

Hello, it still fails after a complete cleanup and reinstall of MacPorts. Please find attached to this message the full port command logs. The specific error comes in the making of the binary:

Any help on how to circumvent this error would be greatly appreciated.

Thanks again.

Somehow the Core Foundation is not being linked in. See

Hello.

This link is not much to help me, but please be aware that I've tried to manually install oldest versions of lftp using this doc: wiki:howto/InstallingOlderPort#install and here are the results:

• lftp 4.9.0 -> same error
• lftp 4.8.4 -> build and install were successful

For some reason your build seems to be linking with the static library libintl.a. When you do that, you need to link with everything the static library requires, in this case including the CoreFoundation framework. However, using a static library is unexpected. Normally the dynamic library libintl.dylib should be used. Does libintl.dylib exist on your system?

libintl is part of gettext and there was a huge overhaul of the gettext port after this ticket was last dealt with so the issue may no longer exist. We had successful builds of lftp 4.9.3 on the buildbot machines, including on Mojave. Can you recheck?
