Linux qt5 build

[giacomo]

hello again, I've followed the Linux build Qt5 page and more I've installed qt5-default, I'm on a debian system.
I've tried to create a package and I got this:

dpkg-buildpackage: source package qlcplus
dpkg-buildpackage: source version 4.10.1
dpkg-buildpackage: source distribution stable
dpkg-buildpackage: source changed by Massimo Callegari <massimocallegari@yahoo.it>
dpkg-buildpackage: host architecture amd64
dpkg-source -I.git --before-build qlcplus-4.10.1
dpkg-checkbuilddeps: error: Unmet build dependencies: libqt4-dev (>= 4.6.0)
dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

Is it easy to fix?
regards

ok, maybe one has to install libqt4-dev too, I'm trying it now..

Start with updating https://github.com/mcallegari/qlcplus/b ... an/control and https://github.com/mcallegari/qlcplus/b ... us.install

I don't know how to force QT5 build. Try changing those two files, hope for the best and when the build fails, try to google dpkg-buildpackage parameters (e.g. https://bhavyanshu.me/how-to-make-debia ... 1/10/2014/ look for rules file)

hi Jano, tried..
and tried again with the original source after the installation of the qt4 packages:
debian/rules:11: recipe for target 'override_dh_auto_configure' failed
make[1]: *** [override_dh_auto_configure] Error 1
make[1]: Leaving directory '/home/gg/qlcplus-4.10.1'
debian/rules:8: recipe for target 'build' failed
make: *** [build] Error 2
dpkg-buildpackage: error: debian/rules build gave error exit status 2

Moved to development forum.

Giacomo, are you aware of automated builds ?
http://www.qlcplus.org/downloads.html
We have Qt5 GIT and released versions for quite a few distros.

By the way, instead of creating a deb package, you can just invoke qmake of a prebuilt Qt5 version.
It's written in the wiki in the "Compile" paragraph. I'll copy here again:

Code: Select all

In general, you can invoke qmake with its absolute path. For example: /home/user/Qt5.4.1/5.4/gcc_64/bin/qmake

In this way you can build QLC+ with any Qt version, located where you prefer in your hard disk. If you wish to build QLC+ with the latest Qt version, you can get it here: https://www.qt.io/download-open-source/

Buongiorno Massimo,
yes I've tried everything before asking help, according to my modest skills!
as written in another post I wanted to control videos with qlcplus, I've tried the builds with xubuntu, kubuntu, debian testing (stable not working with qt5) and arch, compiled from aur and the lastly tried to build with debian testing.
In debian the package qt5-default should solve "You can quickly check if the version is correct by typing: qmake -v", I guess.
If I compile and manual install, what should I do for upgrade later, use the command "make uninstall"?
salute

[mcallegari]

Yes, make uninstall will completely remove QLC+ from your computer.
Otherwise you can simply pull from GIT, make and make install will overwrite the existing installation.

Hi guys,
tried that too. When trying to create a package I got the same result as giacomo.
On a manual install it seems to give me a test-error.

Code: Select all

efx_test.cpp: In member function ‘void EFX_Test::loadDuplicateFixture()’:
efx_test.cpp:2958:5: error: ‘QSKIP’ was not declared in this scope
     QSKIP("Duplicate fixture are allowed because can animate differents parameters (RGB, dimmer, etc.)", SkipSingle);
     ^

But I definitely donwloaded the sources from http://www.qlcplus.org/downloads.html.
Could you tell me where I'm wrong?

EDIT: I'm using Xubuntu 14.04 64Bit trying to build QLC+ 4.10.1 with Qt 5

Apparently the issue is present when building with the Ubuntu 14.04 Qt5 version which is 5.2.1.

I have fixed now on GIT, but you need to download the latest sources, not the released ones.
Or wait for 4.10.2

You're completely right.

Compiling works for now, but creating a package is still not working.

By the way: Will there be automated builds on Qt 5 also for xUbuntu 14.04 in the future?

Have you checked before asking ?
https://build.opensuse.org/package/show ... us-qt5-git

Of course I haven't enabled the released version yet cause the EFX test fix has been done afterward.

At that time I had looked for the released version. But everything is fine since 4.10.2!

Except some translation errors:

Code: Select all

Processing de_DE
lrelease: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/lrelease': No such file or directory
Processing es_ES
lrelease: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/lrelease': No such file or directory
Processing fr_FR
lrelease: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/lrelease': No such file or directory
[...]

I followed the build instructions and built the whole thing with qt5. Do you now how I can tell "make install" where my qt directory is?
