Like other explained, you could use replaced_by to change the port name, so you could have both qt4-qtcurve and qt5-qtcurve for example, with qtcurve being automatically replaced by qt4-curve. My view about prefix vs. suffix: I have a somewhat strong feeling against using the prefix for Qt applications. I would use a prefix for ports and modules that are strictly related to Qt, for example qt5-widgets, qt5-webkit, qt5-sensors, qt5-bluetooth, qt5-doc, ... (basically anything that could be downloaded from the Nokia website, maybe a bit more), but I would never use something like qt5-gnuplot or qt5-wireshark. Maybe gnuplot-qt5 if it has to be, but it feels just wrong to me to prefix random applications that only uses Qt. And honestly I would prefer to keep using "gnuplot +qt5" rather than a separate port. This might be different for modules/libraries/building blocks that other applications need where you actually need to provide both versions. At least until all other dependents upgrade to Qt 5. I don't know what exactly QtCurve does, so I find it a bit difficult to judge to which category it belongs and whether a prefix is justified in that case. But again, that's just my view. Mojca PS: The only reason why I didn't switch to Qt5 in one of my ports was because Qt4 and Qt5 still conflict and I cannot afford to make my port Qt5-only, thus conflicting with many other ports. ___ macports-dev mailing list macports-dev@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/macports-dev

(I'm pretty sure I've seen the minimal OS version set to 10.6 when building Qt5 this week, but not the SDK of course.

My Picking a default isn't the same as imposing it, to the point of throwing in an additional Qt install.

My impression is that the vast majority of installs use only the default variants. We shouldn't shy away from the doing the right thing for (the majority of) our users. I see the Qt5 supports OS X 10.7 and later ('best efforts' for 10.6, if I read it right): http://doc.qt.io/qt-5/osx.html For some ports, if the maintainer wants to keep it running on old OS X versions, they might use Qt4 for older OS environments and Qt5 for newer.

You are welcome (and I and the rest of us...) Someone had to do this... I was hoping a few other MacPorts/KDE-Mac users could try this, esp. those doing work on Qt5/KF5 ... One test that could indicate whether indeed this allows concurrency is to install qt4-mac+concurrent (*not* qt4-mac-transitional) and the current, unmodified qt5-mac . I think that ought to work. a) Traditionally you can install new or development versions of Qt "somewhere else" and point to your test or development version via environment variable $QTDIR. Does this presuppose a fixed hierarchy of directories and names under $QTDIR? If so, changing that hierarchy may cause problems. I think that nowadays the QTDIR "trick" is mostly to use a test version in a different tree with applications that were already linked to your usual version. If so, that means that QTDIR must point to a complete directory and as long as that's the case you should be fine. QTDIR is not (no longer?) required for running. b) Shifting Qt libraries from ${prefix}/lib to ${prefix}/libexec/${qt_name}/lib might be a "no-op". In the lib subdir (/opt/local/lib on my system), Qt libraries are installed as links. For example, libQtCore.dylib, libQtCore.4.dylib, libQtCore.4.8.dylib and libQtCore.4.8.6.dylib all point to /opt/local/Library/Frameworks/QtCore.framework/QtCore, which in turn points to Versions/4/QtCore and THAT is actually a file described as Versions/4/QtCore: Mach-O 64-bit x86_64 dynamically linked shared library. Maybe I am missing something. Yes, you are :) Those frameworks have been moved too. qt4-mac and qt5-mac use a sneaky trick to provide a combined framework and traditional build, based on the fact that an OS X framework is nothing but a shared library (without the usual extension) combined with all associated stuff bundled in a specific way. You can get very close by using --prefix=/Library/Frameworks/foo/Versions/${MAJOR_VERSION} and then setting up a couple of symlinks to disclose certain things a bit more directly. So symlinking framework binaries as you saw makes the link editor can find them ... it already knows how to handle them. All that to say that no, the qt_libs_dir shift is not a no-op. Try it :) and if you didn't install qt4-mac-transitional in the same command you'll get errors from rev-upgrade. Or else you'll see that re-built Qt or KDE applications now link to stuff in /opt/local/libexec/qt4 . Related to the proposed Charm port: https://trac.macports.org/ticket/46575 If I understand correctly, Charm will create subports ala: qt5-charm charm Is this supposed to be a model for going forward? I find the "qt5-" prefix objectionable. Going forward, I believe we will have the following cases: 1) Projects that work with Qt4 but not Qt5 2) Projects that work with Qt5 but not Qt4 3) Projects that work with either Qt4 or Qt5 but differ in non-trivial ways 4) Projects that work with the same with Qt4 or Qt5 Assuming we have co-installable Qt4 and Qt5 via MacPorts, cases 1), 2) and 4) are straightforward: 'port:' style dependencies for 1) and 2) and 'path:' style for 4). In case 3), I think the upstream development plan is important. If upstream is moving to supporting Qt5 and the current differences are due to incomplete support, I think it would be more appropriate to create a '-devel' version of the port until the Qt5 conversion is complete. OTOH, there might be rare cases where users might need to choose between the Qt4 version (more compatible, say) and a Qt5 version (new features). Qt4/Qt5 variants would then be appropriate. FWIW, the project I'm most concerned with, MythTV, has had a working build with Qt5 for a long time and is encouraging testing but it is not recommended for casual users. AIUI, it was not particularly difficult to add Qt5 support even though Myth uses Qt extensively for user interface (including video rendering) and OS abstraction. When upstream is closer to another release (0.28), I plan to create a -devel version using Qt5. Barring show-stoppers, I expect to transition to Qt5 exclusively.
