Can't build vsedit on QtCreator on Ubuntu 20.04

[Selur]

When opening 'apoursynth-editor-2/pro/vsedit/vsedit.pro' in QtCreator and running qmake it uses qmake vsedit.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug and I get Project ERROR: failed to parse default search paths from compiler output also tried to build it using the build instructions without qtcreator, but that failed to.

[YomikoR]

In certain distros there's a standalone debug version for Qt. I never tested with debug build though.

To build following the instructions on Ubuntu 20.04: install libqt5websockets5-dev, and run qmake in the pro folder

[Selur]

I installed libqt5websockets5-dev (apt-get install libqt5websockets5-dev), went to the pro folder ran qmake and got the same error. (same in the pro/vsedit/ folder). Also tried with qmake CONFIG+=release, same issue. (updating with git pull also didn't change a thing)

okay, just noticed this does happen with other projects too -> seems like there's some thing wrong with the qt or compiler setup. -> will report back once I know more

[Selur]

I setup a new 20.04 install and I got a lot further. I also adjusted some code to be Qt 5.12.8 compatible. but know I'm stuck compiling at:

any idea how get libp2p to compile?

[YomikoR]

Looks weird to me, because I did successfully build it in a x64 Ubuntu 20.04.

You may first try building libp2p with its GNU Makefile SIMD=1 make and see what happens.

[Selur]

that works fine,..

selur@ubuntu:~/workspace/libp2p$ SIMD=1 make
g++ -c  -std=c++14 -O2 -fPIC  -DP2P_SIMD  p2p_api.cpp -o p2p_api.o
g++ -c  -std=c++14 -O2 -fPIC  -DP2P_SIMD  simd/cpuinfo_x86.cpp -o simd/cpuinfo_x86.o
g++ -c  -std=c++14 -O2 -fPIC  -DP2P_SIMD  simd/p2p_simd.cpp -o simd/p2p_simd.o

ar rcs libp2p.a p2p_api.o simd/cpuinfo_x86.o simd/p2p_simd.o simd/p2p_sse41.o

since I accidentially reverted all ma adjustements I have to do them again to be Qt5.12.8 compatible (which is the default Qt that comes with Ubuntu 20.04) now it worked,... no clue why but thanks anyways. :)

[YomikoR]

It seems the building failed because -msse4.1 was missing in the args. Did you mistakenly remove it from the .pro file?

[Selur]

that might be the case, not totally sure

[Selur]

for the code to compile on Ubuntu 20.04 with standard qt one needs to do the following changes:

did those quick&dirty, but you should include them with:

  QStringList argumentsList = a_arguments.split(';', Qt::SkipEmptyParts);
#else

for qt5.9.5 (latest on Ubuntu 18.04) some additional changes are needed.

[YomikoR]

Thanks. Some of these changes have been made because they are deprecated in a recent version of Qt5 (or even since Qt4), and will probably be broken in Qt6, see https://github.com/YomikoR/VapourSynth-Editor/issues/6.

I will check building in 20.04 again. But if you have QT_DISABLE_DEPRECATED_BEFORE specified that will be a different story.

As for 18.04, I will probably not install it to take a test. But I guess reverting https://github.com/YomikoR/VapourSynth-Editor/commit/86cb20426af4334d1fc996d3062ed3f1f5d2cee5 (the last commit in the ref list of #6) should be enough.

[Selur]

Some of these changes have been made because they are deprecated in a recent version of Qt5

that is why one usually uses pre-compiler compiler statements. To stay compatible without having to deal with it all the time. (Same when you aim for Qt6 compatibility,..)

Personally I can to the changes myself, but for others it would be better to use pre-compiler statements to stay compatible with current linux distributions.

[YomikoR]

Now have building in 18.04 fixed as well (in WSL, shamelessly...)
