Hi, I should have all dependencies installed, I get until this with make:

I fixed by hand the underscore error in the name of the variable that was discussed in a earlier thread, and get until this with make after that:

Is there something wrong with QT libraries?

Hello,
Which version of Qt are you using? I found this thanks to Google but I'm not sure it will solve the problem

It seems I have both QT4 and 5 installed. I think I had a similar problem with Synthclone, there was a command line option needed that forced to use V4 at compile time, since I think the default is V5 now on my system. I'll need to try that, I think I have it written up somewhere.

The fix for Synthclone was: ./configure --prefix=/usr --qmake="/usr/lib/x86_64-linux-gnu/qt4/bin/qmake"

So I ran /usr/lib/x86_64-linux-gnu/qt4/bin/qmake instead of qmake, command gave no output so I guess was OK. I tried make -j6 and hit the same errors again.

Hi,
I just tried to compile from source and had similar issues.

The source of the problem seems to be in the README file that states.

...
The following libraries are required (the name may vary depending on your system):
- qt (libqt4-dev / qt4-devel)
...

So I installed libqt4-dev, and the rest of the dependencies. (BTW libjack-jack2-dev should be libjack-jackd2-dev)
After a number of attempts to compile I realised that the errors were because the code is using Qt5 methods.
I removed libqt4-dev and installed qtbase5-dev and also needed to install libqt5svg5-dev.
I also needed to do a make distclean to get the correct libraries to link. I think that just removing .qmake.stash may have been enough.

In Summary


make distclean
apt remove libqt4-dev
apt install qtbase5-dev
apt install libqt5svg5-dev
qmake && make -j6
cd RELEASE
./polyphone

Hi all.

I'm trying to compile on Ubuntu Mate 18.04
I installed all the prerequisites and ran
qmake-qt4 && make

I got all the _qscrollX errors and fixed them by putting in the underscore. Now I have this:


pages/graphicsviewenvelop.cpp: In member function ‘void GraphicsViewEnvelop::setPosX(int)’:
pages/graphicsviewenvelop.cpp:166:28: error: invalid use of incomplete type ‘class QScrollBar’
         if (this->_qScrollX->maximum() > 0)
                            ^~

What now?

Try to add the following line at the top of the file "graphicsviewenvelop.cpp"#include <QScrollBar>

Thanks, Davy.

I did that, then got this:

pages/graphicsviewenvelop.cpp:323:18: error: ‘class QVector<double>’ has no member named ‘length’
         if (data.length() - currentSmplPos < nbRead)
                  ^~~~~~

This error repeats a number of times in the lines following the above. Is there some declaration missing?

Thanks, Davy.

I had actually read the thread, and the other recent one on this subject, and I have tried all the suggestions. I am obviously missing something.

I loaded Qt Creator, and it came up with the same errors.

So now neither Swami nor Polyphone runs on the latest Ubuntu. I have no soundfont editor to use with Fluidsynth.

I'm pretty sure this is a Qt4 vs. Qt5 issue. If you have a look at

Qt 4.8 QVector docs
and
Qt 5.11 QVector docs

you will see that the length() method was not available in Qt4.

So it seems that you are still linking against the Qt4 libraries. Have another look at my previous post, there may be some other packages that you have installed that need to be removed, or perhaps an 'apt-get purge libqt4-dev' is needed.

BTW: I am not a Qt expert, so there may be some Qt4/Qt5 configuration that I am missing, but what I posted earlier worked for me. YMMV

Have Fun,
JL

Thanks all.

I went back to scratch and redid all your steps John, and I had to re-create a link from /usr/bin/qtmake to the QT5 executable. Now it works. Obviously I had something left over from the original README.

Note that you can't (well, I can't) double-click the executable from the desktop and make it run. It only works from the command line or via a launcher.

Note also that those edits for _qscrollX, etc are not necessary.

Thanks for all the help.

Thanks John Lemcke, this worked for me. Just one comment: there's no need to install libqt4-dev. You can link to the correct libraries by replacing the "qmake" command with "qmake -qt=qt5"
