Compiling Ysem on raspbian

[rfreiha]

Hello

I am trying to compile yasem on raspbian. I installed all the required packages. I am getting an error when i run the make command:

systemstatisticsimpl.cpp: In member function ‘virtual QString yasem::PlatformInfoImpl::archName() const’:
systemstatisticsimpl.cpp:134:12: error: ‘currentCpuArchitecture’ is not a member of ‘QSysInfo’
return QSysInfo::currentCpuArchitecture();
^
systemstatisticsimpl.cpp:135:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^

Any feedback is appreciated

Hi. It looks like you're using an old version of Qt. QSysInfo::currentCpuArchitecture() was added in Qt 5.4, so either try to use a newer version of the library, or just remove this call and return some value (like "arm") from PlatformInfoImpl::archName().

Can you please guide me on how to do that?

[mvasilchuk]

Open systemstatistics.cpp and replace
return QSysInfo::currentCpuArchitecture();
by
return "arm";

I will give it a try shortly and ket you know. Donyou know if someone has this working on the Raspberry pi?

[mvasilchuk]

I don't know. I've tried to run the app on RPi2 a while ago, but it didn't work because of some OpenGL error (don't remember which one).

Now i am getting this error:

openglwidgetcontainer.h:4:25: fatal error: QOpenGLWidget: No such file or directory

so i reinstalled Ubuntu mate on the Raspberry PI 3. i successfully compiled YASEM on it. once finish i set it up with my portal. the portal load but can play any channels. it give an error: no decoder for type application/x-hls
any ideas?

[mvasilchuk]

Try to install gstreamer:
sudo apt install gstreamer1.0-*
(or just individual packages from gstreamer).

[rfreiha]

Sounds good. I will try it and let you know.
If i want to extract what ever i compiled so i can use it on different raspberry pi what files do i need to take out? Should i copy the yasem folder?

update - now i am getting this error
va_getDriverName() failed with unknown libva error,driver_name=(null)

Try to run the app with environment variable QT_DEBUG_PLUGINS, so you'll be able to see more info about this issue.
For example, it can be set in Qt Creator on project settings tab (just add this variable with any non-zero value).

Also, as far as I can see in your error output, there is some issue with libva library. Check if this library is installed and if OpenGL works in X11 (run glxgears, for example).
