Planned maintenance has been done but it did not solve the problem. So work will continue on this and a new time for trying updates will be announced asap.
Hi,
we'd need to know the mirror/IP which is used by the installer? If this error is still valid would it be possible for you to use e.g. Wireshark to check the mirror IP?
Hi,
afaik it should suffice to sign and notarise .app bundles and .dmg files:
To sign the .app bundle (you need to use your own ID's, keys etc. naturally):
unlock_keychain()
s_arg = 'Developer ID Application: The Qt Company Oy ({0})'.format(os.environ['QT_CODESIGN_IDENTITY_KEY'])
# "-o runtime" is required for notarization
cmd_args = ['codesign', '-o', 'runtime', '--verbose=3', '-r', '/Users/qt/csreq_qt_company.txt', '-s', s_arg, file_path]
Then to notarise the .dmg file you can use the following Python script:

@Mark81 said in Questions about official procedure for cross-compilation for RPi:
I found this "modern guide" for cross-compiling Qt for Rasbian.
Few questions:
anyone tested this for RPi4?
Yes, many people. It does not work due to changes in GPU drivers in PRi4.
Great.... :-(
Obviously, you are missing developer versions of the libraries. Those should be listed in requirements somewhere?
On Debian-like systems (here: Ubuntu) those should be listed as <package-name>-dev.
Hi, and welcome!
@JCDFr said in How I know which components to downoad:
So I tried, but when I launch Qt creator it says there is no available kit nstalled.
In simple terms, "Kit" = "Qt Version" + "Compiler".
Your development machine needs a C++ compiler, plus a copy of Qt that is compatible with that compiler.
Usually, you must install your compiler separately (e.g. Get g++ from your Linux distro, or MSVC from Microsoft).
It is for developping a plug in on libreCAD and how am I sure the Qt components will be downloaded ?
Since this is a plugin, you must also make sure that your compiler is compatible with the version if libreCAD that you are using.
@BryanTriana Could you tell me how you made it to work? I did all of the above and still get the error "This application failed to start because no Qt platform plugin could be found". I created a msix package for the Windows store successfully, app get's installed, but fails to start.
@Nima-Ghorab hi Could you help to list all steps that you used like as which version of mysql (best list address you dowload)
which openssl ( if need download it) which comply line command .
Many thanks for your help.

What gives? What am I doing wrong? Thank you.
You're probably hardcoding widget sizes. See High DPI Displays. To fix this "Replace hard-coded sizes in layouts and drawing code with values calculated from font metrics or screen size".
Excellent, thank you. Setting the QT_AUTO_SCREEN_SCALE_FACTOR environment variable was an instant (if inelegant) fix. I'll look into the other options more closely. Appreciate the help.
Yes, because opengl calls get transpiled into WebGL, which is based on OpenGL ES 2/3, although has more strict rules.
You can get emscripten to emulate older desktop OpenGL 1 calls though.

Thank you for your reply.
Unfortunately the log doesn't tell me much. The log <./Src/qtbase/src/plugins/sqldrivers/config.log> reads as follows ...

Is this the 'test' log that you were referring to?
I found the issue , the problem was with db2/qsql_db2.cpp file which calls SQLDriverConnect with qToTChar(connQStr) param.
I enabled db trace and checked DB2 received only one char instead of the full connection string.
I changed it to (unsigned char ) connQStr.toLatin1().data()* and it worked.
Now the problem is the queries called from exec() function with below error
[IBM][CLI Driver][DB2/LINUXX8664] SQL0104N An unexpected token "END-OF-STATEMENT" was found following "s". Expected tokens may include: "JOIN <joined_table>". SQLSTATE=42601
Is QT5 by default UNICODE enabled ? how do I disable it ?
@stvokr
I think the product code is specified in the original msiexec package you installed, i.e. it's a resource in the .msi file. Then it may or may not change as new versions of that .msi are produced.

Cloud you share which link for download Mysql Connector c++?
When build a static qt with mysql , the Mysql Connector c++ is a big problem .
Seems mysqlclient.lib is complied by MinGW,if use build a static qt by VS and include mysqlclient.lib(build by MinGW) will get failure.
Did you try build a static with mysql by VS?
@shebin It is probably possible to cross-compile from Windows, but I really would suggest to do it on Linux as it is way easier. You can use a virtual machine with Linux running on your Windows machine.
Hi @jsulm ,
thank you very much for your assistance!
Now I can compile it without any failures!
I think this is a problem with qts touch screen drivers for the raspberry.
Maybe the system does not forward any signal from the touch screen.
It's funny because it works if I use on the pure system. I can make everything.
It works also If I create a widget using qt IDE on raspberry itself.
But it does not work if I try to cross compile and ruining remotely.
Has anybody an idea whats happened?
Thanks to everybody in advance for any help.
