orbit2: error: implicit declaration of function 'g_mutex_free' is invalid in C99

[jon22706@…]

org.macports.build for port orbit2 returned: command execution failed is the error I get.

[cooljeanius (Eric Gallager)]

This was not a clean build attempt. Do sudo port clean orbit2 and then try again, and if that still fails, attach the main.log from that attempt.

[jon22706@…]

Unfortunately that didn't work. Here is the Log

This appears to be part of the deprecated glib thread API.

​https://developer.gnome.org/glib/2.32/glib-Deprecated-Thread-APIs.html

We need to either figure out how to re-enable that API, or rewrite orbit2 to use the new glib thread API.

Here is the upstream bug report: ​https://bugzilla.gnome.org/show_bug.cgi?id=696900

It looks like it's also due to -Werror; would disabling -Werror temporarily until upstream fixes this work as a workaround?

[jon22706@…]

How would I disable -Werror?

Replying to jon22706@…:

I was referring to disabling it in the Portfile, although I suppose you could try doing that yourself...

[ryandesign (Ryan Carsten Schmidt)]

Even once you remove -Werror you still have:

:info:build linc.c:464:4: error: use of undeclared identifier 'G_THREAD_PRIORITY_NORMAL'
:info:build                  G_THREAD_PRIORITY_NORMAL, &error);
:info:build                  ^

I don't think the error messages are wrong; I think ORBit2 uses an old thread interface of glib which no longer exists; the compiler is quite right that trying to use functions and constants that don't exist won't work.

ORBit2 seems to be dead so I'm not sure that its developers, if any are still around to read the project's bug reports, will do anything about this.

The correct solution may be to update all the ports that currently use ORBit2 to no longer do so, and then remove ORBit2 from MacPorts. Those ports are:

• bonobo-activation
• gconf
• gnome-platform-suite
• libbonobo
• libgtkhtml3
• py-orbit
• py25-orbit
• py26-orbit
• py27-orbit
• xmlroff

py*-orbit obviously isn't much use without orbit itself, so this would also affect ports depending on py*-orbit, which includes:

• gnome-bindings-python
• py25-gnome
• py26-gnome
• py27-gnome

[dbevans (David B. Evans)]

In fact, since libbonobo depends unconditionally on orbit2 and libgnome, libgnomeui and friends depend on libbonobo any GNOME 2 app that uses these libraries (still quite a few) would be impacted by the suggested removal.

The symbols in question are deprecated in the latest version of glib2.

Fix committed in r104857 which allows the use of the deprecated symbols by removing all instances of -DG_DISABLE_DEPRECATED.

Oh neat! Thanks.

Looks like gnome-vfs may need something similar: #38657.
