I tried to run a python program on the PyQt5 framework but it's giving me .dll file errors.
I've installed tools to fix it but it's still giving me this error :
OSError: cannot load library 'libxcb.dll': error 0x7e
I have already installed all these tools:
**Uniconvertor-2.0rc5-win64_headless.msi
GTK+ for Windows Runtime Environment Installer**
it always gives me this error "OSError: cannot load library 'libxcb.dll': error 0x7e".
Is there any other way to fix this error?

I built qt-gstreamer from source code on GitHub (version 1.2.0). Then I tried to run qmlplayer2 application (built from qt-gstreamer and use qtquick2videosink) on qt5 on Raspberry Pi3 but I got the following error at runtime:
(gst-plugin-scanner:3749): GStreamer-WARNING **: Failed to load plugin
'/usr/lib/gstreamer-0.10/libgstqt5videosink.so':
/usr/lib/gstreamer-0.10/libgstqt5videosink.so: undefined symbol:
_Z33gst_qt_quick2_video_sink_get_typev Failed to create qtquick2videosink. Make sure it is installed correctly
(qmlplayer2:8517): GStreamer-CRITICAL **: gst_bin_add: assertion
'GST_IS_ELEMENT (element)' failed
(qmlplayer2:8517): GStreamer-CRITICAL **:

failed
Look at source code of qt-gstreamer, i found that the function gst_qt_quick2_video_sink_get_type() is implemented in gstqtquick2videosink.cpp but this file was not compiled due to missing configuration in cmake related to OpenGL.
I config cmake as below :
then rebuild and deploy new file libgstqt5videosink.so to /usr/lib/gstreamer-0.10/libgstqt5videosink.so on target device. After that qmlplayer2 application work fine.
I am trying to setup Agora recording setup, I have complied the samples provided in bundle and trying to run them. I am getting following exception where code is unable to find recording.dll
Exception in thread "main" java.lang.UnsatisfiedLinkError: no recording in
java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867)
at java.lang.Runtime.loadLibrary0(Runtime.java:870)

at io.agora.recording.RecordingSDK.<clinit>(RecordingSDK.java:24)
This doesn't look like an Agora error rather a Java error. The function is not finding a dependent method in its link path, you can check which function its failing on, and then check if you have a path mismatch in your compilation path
You can do java -XshowSettings:properties -version and then look at the value of java.library.path to see the library paths.
I follow an example in kernel.org to write an i2c driver but unfortunately when i compile i got this warning
WARNING: "i2c_register_board_info" [/home/pi/builddriver/samplei2c/pn535.ko] undefined!
Although compile with 1 warning and no error, I cannot insmod module. this is error when insmod
insmod: ERROR: could not insert module pn535.ko: Invalid module format
My question is how to solve the warning above?, I think it make .ko file to be invalid. Here is my source code on
pastebin
thank for your help!
That is not possible in a kernel module simply because the function i2c_register_board_info is not exported from the kernel source tree to the kernel modules (built using obj-m targets). You can achieve this by building your driver within the kernel source tree using (obj-y targets).
