QUESTION
I'm trying to unpack .tar.gz file to my root during the building system, but it doesn't work because of an unclear reason for me. I did it in the same way as other recipes in my meta (which works fine), but in this case, I have an empty directory in the target system root. The recipe has the same name as tar.gz.
Based on Yocto Project Documentation and my other experience it should work fine. I tried to remove manually tmp, sstate-cache directories and rebuild system, but it doesn't change anything. The recipe is building, but the /my-app is empty. Can I force extract my archive?

...ANSWER
Answered 2022-Mar-02 at 15:57As mentionned in the link you provided that:
The unpack call automatically decompresses and extracts files with ".Z", ".z", ".gz", ".xz", ".zip", ".jar", ".ipk", ".rpm". ".srpm", ".deb" and ".bz2" extensions as well as various combinations of tarball extensions.
it extracts .gz
automatically into ${WORKDIR}
.
The issue with your recipe is that you are creating /my-app
but not filling it with any content.
Keep in mind that the compressed file is unpacked under ${WORKDIR}
, so install it into ${D}/my-app

QUESTION
I'm attempting to implement a subclass of QQuickAsyncImageProvider
in Pyside6, referring to the official example. I'm already aware of the potential hurdle that, unlike in the C++ example code, with PySide it's not possible to inherit from both QRunnable
and QObject
. In order to send a signal from my QRunnable
I'm instead using an intermediary QObject
, as suggested here. That part works fine.
Here's my attempt so far at using this arrangement along with my own subclass of QQuickAsyncImageProvider

ANSWER
Answered 2022-Feb-22 at 13:19I reported this in case it was a bug, and one of the maintainers realized that the issue is that the AsyncImageResponse
gets immediately deleted. The workaround for this is to hold a reference to it in the AsyncImageProvider

Answered 2022-Feb-09 at 12:24It turned out that this is a bug on Qt's side : https://bugreports.qt.io/browse/QTBUG-94524 ( Introduce a QT_ADDITIONAL_HOST_PACKAGES_PREFIX_PATH variable ) .
The same script should work, once that fix will be deployed.

I have been building Qt 5 for a long time successfully on Windows using GCC/MinGW-w64. When I try the same with GCC 11.1, the build fails with a strange error message. What can I do to make it work?
I have built the compiler myself using the develop

ANSWER
Answered 2021-Jun-22 at 10:00There are several issues to solve.
First I have to patch Qt, since with GCC 11 some header dependencies have changed and Qt 5.13.2 does not always include the right headers (see https://gcc.gnu.org/gcc-11/porting_to.html or How Can I Include Header Files by Compilation Flags?).
Therefore I add the line
