Error appears to be:

[kencu (Ken)]

Yuk. Picking up the wrong libiconv now....

hopefully not caused by: [e6d093a57f6a86b0ace628ff70d6ec79fd3808ee/macports-ports]

[kencu (Ken)]

I can't build this either. Similar error.

  Referenced from: /usr/lib/libmecab.1.0.0.dylib

[kencu (Ken)]

Michael -- if you get a moment, please see if you can try to build this.

It builds fine before the commit to gobject-introspection but won't build after that commit. Must be something to do with DYLD_LIBRARY_PATH but it's not easy to see the enviroment settings when g-ir-scanner runs.

[kencu (Ken)]

libsoup is broken too:

dyld: Symbol not found: _iconv
  Referenced from: /usr/lib/libmecab.1.0.0.dylib
  Expected in: /opt/local/lib/libiconv.2.dylib
 in /usr/lib/libmecab.1.0.0.dylib

[michaelld (Michael Dickens)]

Arg. Thanks for the prod, @kencu. Let me start building locally & see what I can work out ...

[michaelld (Michael Dickens)]

I see this too on py*-gobject3 ... probably others. After some testing, I think I have a solution that's robust. The issue keeps being that -L${prefix}/lib is appearing in the link commands! PR coming shortly for testing. Works for me on 10.15 Xcode 12 for both py38-gobject3 as well as gexiv2.

[michaelld (Michael Dickens)]

Please test this PR: ​https://github.com/macports/macports-ports/pull/8985

[michaelld (Michael Dickens)]

In 8fb49743e47074c890d88f03de4528857b495dcb/macports-ports (master):

gobject-introspection: tweak scanner patch

Now handles build-provided library paths more robustly, removing those that are found via PKGCONFIG and are thus clearly "system" paths.

Ref: #61382

[michaelld (Michael Dickens)]

I'm going to go ahead and close this ticket as "fixed". Since testing by me and others shows that the tweaks added do indeed fix this and all known related build issues when using our modified GO-I. Please reopen if you still have issues & post a new build log along with the port(s) showing issues.

[kencu (Ken)]

Well done, Michael -- thanks.

[31n81t (Maigurs)]

Gimp by itself builds and installs but when I launch it it appears on dock for short time and disappears (other words does nothing). When I launch Gimp from terminal I got message Cannot open display:

Btw thanks for quick response! Thank you.

Regards

[jmroot (Joshua Root)]

Please open a new ticket for the new issue.

I know Michael requested to "reopen if you still have issues" but he meant issues with gobject-introspection.
