mingw-w64-x86_64-gtkmm3-3.24.3-* linking issue about Gtk::TextIter

[giuspen]

last good is mingw-w64-x86_64-gtkmm3-3.24.2-1-any.pkg.tar.xz (I manually downgraded from http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-gtkmm3-3.24.2-1-any.pkg.tar.xz) since the switch to 3.24.3 I have several linking issues such as:

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: libcherrytree_shared.a(ct_actions_edit.cc.obj):ct_actions_edit.cc:(.text$_ZN4Glib7ustringC1IN3Gtk8TextIterEEET_S4_[_ZN4Glib7ustringC1IN3Gtk8TextIterEEET_S4_]+0x54): undefined reference toimpZN3GtkneERKNS8TextIterES2`

The issues disappear as soon as I downgrade:

pacman -U mingw-w64-x86_64-gtkmm3-3.24.2-1-any.pkg.tar.xz

Do you have a program or sample code to test?

[giuspen]

I do: https://github.com/giuspen/cherrytree/blob/master/README.md#building-cherrytree-on-windows

Thanks @Biswa96

Interesting, I build the project in ArchLinux without any error, with the same version of gtkmm3 library. Also the overloaded operator is defined in treeiter.h header file. Why linking error? 🤔

[jeremyd2019]

Probably another oversight in the change in how symbols are exported, like https://github.com/msys2/MINGW-packages/commit/f2b9f3f47fc68de84e748331200c6263d9640029

I get this error while installing the package :

$ pacman -U mingw-w64-x86_64-gtkmm3-3.24.2-1-any.pkg.tar.xz

loading packages...
error: 'mingw-w64-x86_64-gtkmm3-3.24.2-1-any.pkg.tar.xz': could not find or read package

I am using Pacman v5.2.2 - libalpm v12.0.2

[abidrahmank]

Providing full link to pacman worked for downgrading.

pacman -U http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-gtkmm3-3.24.2-1-any.pkg.tar.xz

[Biswa96]

@abidrahmank To use -U option, you have to provide the package file path or a link from a mirror. See man pacman for further details.

Hi, we are currently facing the same issue with the windows build for NoteKit.

This affects not only native builds with msys2/mingw but also our Fedora mingw cross compiles. It works on Fedora 33 (mingw64-gtkmm30 3.24.2-3.fc33) but it's broken on f34 (3.24.4-1.fc34). Manually downgrading mingw64-gtkmm30 on f34 to the f33 works.)

[giuspen]

Would it be possible to upgrade gtkmm3 package to 3.24.5? I saw few commit comments that make me hope this issue is fixed.

[sp1ritCS]

I just built gtkmm 3.24.5 from source, it's fixed:

I built and installed the package for gtkmm3 3.24.5 and subsequently built successfully cherrytree. I created a pull request, I hope it will be merged.

[sp1ritCS]

It's not only gtkmm with fixed dllexports, atkmm, pango and pangomm apparently too.

https://bodhi.fedoraproject.org/updates/FEDORA-2021-da7e20915b

Maybe add them to the PR?

[giuspen]

One thing at a time

[Biswa96]

I have updated those in another pull request.

[giuspen]

Thanks @Biswa96
