qt3: links with libGLU though no dependency declared

[mattoon1@…]

Trying to install xxdiff on a new Macbook Pro.

Software version information: OS X 10.10.3, XCode 6.3.1 (6D1002), MacPorts 2.3.3

All dependencies seem to have installed without a problem, so the entire log when I try installing xxdiff is now:

sudo port install xxdiff

The log gives this reason for the problem:

:info:build dyld: Library not loaded: /opt/local/lib/libGLU.1.dylib
:info:build   Referenced from: /opt/local/bin/uic
:info:build   Reason: image not found

So it looks like xxdiff builds with uic (a part of qt4-mac), and that uic is linked with libGLU (from the libGLU port), but that libGLU is not present now. You could work around the problem by installing the libGLU port:

sudo port install libGLU

On my system, uic does not link with libGLU. Do you perhaps have qt4-mac installed with the +openvg variant? I see that that variant adds a dependency on mesa, and I know that mesa used to provide libGLU, but that libGLU was split off into its own port recently. The +openvg variant may need to have a dependency on the libGLU port added.

[mattoon1@…]

sudo port install libGLU

followed by

sudo port install xxdiff

worked fine: I can now use xxdiff. As for qt4-mac, I do not have it installed:

port installed | grep qt
  qt3 @3.3.8_14 (active)

From your answer it sounds like you were expecting xxdiff to use qt4 instead? I notice another recent tracker item (​https://trac.macports.org/ticket/44526) that modifies the port file to use qt4, but that doesn't seem to be the default right now.

What does "port provides /opt/local/bin/uic" return?

Replying to michaelld@…:

>port provides /opt/local/bin/uic
/opt/local/bin/uic is provided by: qt3

OK; so this is a qt3 issue, not a qt4 issue. Is there any reason you can't use qt4-mac instead of qt3? Qt4 is still being maintained, and they even expect a new release sometime later this year. Given how old qt3 is, I think the best we can do is just add the dependency to the port; I don't think anybody has really touched that port in ages.

Yes, I'm happy to try qt4. In fact, the only reason I have qt3 is installed is that it was on the list of dependencies for xxdiff. How should I proceed with using qt4? I assume the xxdiff portfile needs to change to show the new dependency?

[michaelld (Michael Dickens)]

xxdiff is at 3.2, which is quite old & looks to work with Qt3 and older Qt4; probably won't work with the current qt4-mac.

xxdiff 4.0 looks like it should work with current qt4-mac, but it's non-trivial to do the update -- some patch fixes & other changes to the Portfile.

so, I think adding in a dependency on libGLU is the way to go for now -- simple and quick!

[michaelld (Michael Dickens)]

Done in r136235. Thanks for reporting this! If you want xxdiff updated to 4.0, please create a new ticket to that effect & add me as owner & I'll see what I can do.

#44526 is already open for this.
