@SpotlightKid: No, the patch is relevant for qt5 >= 5.13 (only actually). The qt4 bits stay in place, but for qt5 it's relevant as some parts of the code otherwise get namespaced and lead to compiler errors.

SpotlightKid commented on 2019-07-09 10:54 (UTC)

@Teteros: Isn't this patch only relevant, if you compile with Qt4 support at all? This PKGBUILD recently turned off Qt4 support by passing HAVE_QT4=false to make.

You can apply in the PKGBUILD as usual:

source=("$pkgname"::"git://github.com/falkTX/Carla.git" "fix_qt5.13_moc.patch")
md5sums=('SKIP' 'SKIP')

prepare() {
  cd "$srcdir/$pkgname"
  patch -p1 < "$srcdir/fix_qt5.13_moc.patch"
}

@milk: I just pushed a new version, which drops support for Qt4 completely. If you want to use LV2 plugins with a Qt4 GUI with Carla, you have to edit the PKGBUILD file and remove the HAVE_QT=false lines (and install the qt4 AUR package of course) and rebuild.

SpotlightKid commented on 2019-06-24 09:49 (UTC)

@milk: I didn't realize, 'qt4' is in the AUR now (on Manjaro, it seems, it is still in the 'community' repos). Alas, to build the LV2 bridge for LV2 plugins using Qt4, you still need Qt4 at compile time. But at least on my system there seem to be no LV2 plugins actually linked against Qt4.

Here's the command I'm using to check:

find /usr/lib/lv2/ -name "*.so" | while read so; do ldd "$so" | grep -H 'QtCore\.so\.4' ; done

Let me think about this for a day or two...

milkii commented on 2019-06-23 16:28 (UTC)

Can qt4 be removed from makedepends as it is in optdepends? Qt4 takes two hours to build on my system and I want shot of it.

SpotlightKid commented on 2019-05-02 17:01 (UTC)

'qt5' is indirectly required by 'python-pyqt5', which is in the 'depends' list. All 'depends' packages are automatically make dependencies as well. 'qt4' is only in 'makedepends' and in 'optdepends', because it is only required for plugins using Qt4 and building the Carla plugin bridge for those. Carla itself only uses Qt5 nowadays, I think.

Terence commented on 2019-05-02 16:54 (UTC)

Shouldn't the qt4 makedepends be replaced with qt5?

SpotlightKid commented on 2019-02-18 17:41 (UTC)

Please do not flag this package as out-of-date, only because the version number shown on this page is less than that of the latest release. This is normal for VCS packages such as this one. The version number is automatically updated when you compile the package.

Please read: https://wiki.archlinux.org/index.php/Arch_User_Repository#Foo_in_the_AUR_is_outdated;_what_should_I_do?

@SpotlightKid without qt5-svg the error is:
