Compilation errors

[Christian Vogl]

Hi!

I just wanted to install SSR, but compilation fails on my Archlinux machines (Thinkpads with kernels 4.4 resp. 4.8), but failed with GUI, whereas without GUI I was successful.

I

So it seems as if SSR was not compatible with QT4.8 (?) or my QT5.7 (?)

configure gives the following:

I'm a bit confused about the use of qt4 here (which I have also installed) – main qt version would be qt5.

But Makefile states explicitly qt4, so I guess this is ok.

make then stops at 

make[2]: *** [Makefile:1125: gui/qclicktextlabel_moc.o] Error 1
make[2]: Leaving directory '/home/voc10004/priv/auch_musik/ssr/ssr-0.4.1/src'
make[1]: *** [Makefile:840: all] Error 2
make[1]: Leaving directory '/home/voc10004/priv/auch_musik/ssr/ssr-0.4.1/src'
make: *** [Makefile:481: all-recursive] Error 1

When it entered compiling  _moc, it already showed the following error:

gui/qclicktextlabel_moc.cpp:15:2: error: #error "This file was generated using the moc from 5.7.0. It"
 #error "This file was generated using the moc from 5.7.0. It"
  ^~~~~
gui/qclicktextlabel_moc.cpp:16:2: error: #error "cannot be used with the include files from this version of Qt."
 #error "cannot be used with the include files from this version of Qt."
  ^~~~~
gui/qclicktextlabel_moc.cpp:17:2: error: #error "(The moc has changed too much.)"
 #error "(The moc has changed too much.)"

QT's  moc is installed:

> moc-qt4 -v    
Qt Meta Object Compiler version 63 (Qt 4.8.7)

Any hint what I could change in configuration to also get the GUI?

Thanks in advance,

Christian

Hi Christian.

Yes, the SSR uses Qt 4 for now, but very soon it will use Qt 5, see
https://github.com/SoundScapeRenderer/ssr/pull/58.
If you want, you can already try this branch.

If not, here are some hints which maybe help:

The configure script searches for a program called "moc" and I guess
in your case it finds the Qt 5 version of it.
If you have local bin directory -- e.g. $HOME/bin -- you could try to
make a symbolic link there with the name "moc" linking to "mod-qt4".
If not, you could try temporarily disabling the "moc" binary and
renaming "moc-qt4" to "moc".

Alternatively, you could open configure.ac, search for "moc" and
change it to "moc-qt4".
Then you'll have to run ./autogen.sh to update the configure script.

cheers,
Matthias

Hi Christian.

Have you been successful in compiling the SSR with Qt4 in the meantime?

I just found out that there is a much simpler way to select Qt4, this
maybe also works on Arch Linux:

export QT_SELECT=4

You'll probably need the "qtchooser" package for that to work.

On Debian, there is also a "qt4-default" package, which selects Qt4 as
system-wide default.

cheers,
Matthias

Hey Matthias,

with moc-qt4 it did not compile.

But I tried the qt5 approach on Friday, with  chohner's pull request on one of my machines: 

after a bit of PIC-tinkering I was able to install SSR with GUI.

Thanks for your support!

I'll try the qt-chooser approach on the other machine this week and let you know!
