Can't build 0.7.9 on Ubuntu 16.04 64-bit

Forums

Hello, I haven't had any success building qtractor. When trying to build for either Qt4 or Qt5 I get the following errors:

In file included from qtractorAudioEngine.cpp:35:0:

In an attempt to get things to just compile I use the following:

./configure --enable-vst=no --enable-libsamplerate=no --enable-librubberband=no --enable-libvorbis=no --enable-libmad=no --enable-liblo=no --enable-dssi=no --enable-lv2=no --enable-lilv=no --enable-nsm=no

I used sudo apt-get build-dep qtractor to make sure I have the dependencies.

Does this look familiar or obvious to anyone?

Thanks for your wisdom.

re. Can't build 0.7.9 on Ubuntu 16.04 64-bit

i suspect you're still trying to build on an system which fails or is incomplete on dependencies on either Qt4 or/and Qt5 build dependencies.

i have no big field experience on ubuntu, but you can try following the following basic (theoretical) steps :

install all the necessary build dependencies (mandatory are in bold):
sudo apt-get update
sudo apt-get install qtbase5-dev qtbase5-dev-tools qttools5-dev-tools qtchooser
sudo apt-get install libx11-dev x11proto-core-dev, libqt5x11extras5-dev
sudo apt-get install libjack-dev libasound2-dev libsndfile-dev ladspa-sdk libvorbis-dev libsamplerate-dev
sudo apt-get install libmad0-dev librubberband-dev dssi-dev liblo0-dev zlib1g-dev
sudo apt-get install lv2-dev liblilv-dev libsuil-dev
on the source tree, start on a clean slate:
./autogen.sh clean
./autogen.sh
main build, from source:
export QT_SELECT=5
./configure
make
finally, if so desired, install from source:
sudo make install

hth.
cheers

Excellent, thank you very

Excellent, thank you very much. The trick seemed to be removing "--enable-vst=no" from my configure line. I didn't actually install anything just now because everything was already there except the Qt5 packages, and I already had the full Qt5 tools installed and didn't want to have two variants of Qt5 stuff.

I stumbled a bit getting configure to work and crossed a point where that switch was now not helping me. Here are the "tweaks" that I think were necessary for me:

I installed the full Qt5 package from their web site, and after much head scratching to get qmake detected by ./configure I ended up doing
```
    ln -s /<my-qt5-install-dir>/5.7/gcc_64/bin/qmake /usr/bin/qmake-qt5
```
I feel like there is a more proper way to do this, but none of the info I found, particularly about qtchooser, seemed to solve locating my Qt5 binaries.
Specify
```
    CXXFLAGS='-std=c++11'
```
in the ./configure options.
DO NOT specify
```
    --enable-vst=no
```
in the ./configure options.

It's building and running now.

Thanks again!
