How can i fix this?

QtCore -I. -I. -I/usr/lib64/qt5/mkspecs/linux-g++ -o FacilityEngine.o FacilityEngine.cpp
FacilityEngine.cpp: En la función miembro ‘virtual void* FacilityEngine::prepareOpusAudio(const std::string&, QBuffer&) const’:

Hi,
Can you details me what you try compile and how?
missing:
#include <QCoreApplication>

[StefanPofahl]

For me it is similar:
OS: Ubuntu 22.04
1.)

sudo apt install make gcc qtmultimedia5-dev libogg-dev libopus-dev libgl1-mesa-dev

2.) Download zip of Master
3.) Extracting
4.) change to folder
5.) building

find ./ -name '*.ts' -exec lrelease {} \;
qmake ultracopier.pro
make -j$(nproc)

6.) Error message

Try after:
apt-get install build-essential gcc automake bc libncurses-dev flex bison libssl-dev

[StefanPofahl]

Thanks! Unfortunatly, the error message is still the same.

[alphaonex86]

Maybe this can help:
https://askubuntu.com/questions/1387067/usr-include-stdio-h2710-fatal-error-bits-libc-header-start-h-no-such-file
Else insert as the first line other-pro/ultracopier-core.pro:
DEFINES += NOAUDIO
this will try compile with audio

[StefanPofahl]

Thanks, for the tip! - Now it looks a bit more promissing during compilation, but it was not successfull at the end ... :-(
The error message is now:

Could it make sense to specify upfront the correct python-skript interpreter?
I have Julia installed on my machine, and it seems, as if the python interpreter included in Julia is taken ...

Same seam be same error, but this part is needed. python have not link to this project because this proyecto don't have part into python
