  Hi @rsacchettini, Clang is a double-sided sword. If it works, it gives you fantastic insight in your code - but if not, you often have no idea why. I'd recommend you nevertheless to start an own discussion topic here, we might be able to help you get it at least running. Can you at least work on a small example project? Also note that the CMake integration is in flow currently, so there might be regressions in .0 releases. You might want to try the last stable or the next snapshot release.

  @vyau said in QtInstaller framework silent install option: Is it available to my installer that I packaged using QtInstaller? Yes. If this is available, does that mean I can fire off my installer without needing a windowing system handy (e.g. I ssh to remote host and not sending X traffic back)? Yes you can use it via ssh. But you do need a windowing system installed, I think it will fail to run without it (maybe I'm wrong).

  @MatteoB said in QtSerialPort problems with the continuous reading of data from the serial port: void MainWindow::ReaderH() { quint64 X=20; serial->waitForReadyRead(); m_readData=serial->QSerialPort::read(X); //if (!m_timer.isActive()) // m_timer.start(5000); inter2=QString(m_readData); QStringList firstlist2= inter2.split(";"); m_readData3=firstlist2.takeFirst(); H=m_readData3.toFloat(); qDebug() <<"Data:"<<m_readData<< " \r\n"; //QThread::sleep(11); } I think you have 2 problems with your implementation: first: mixing pooling mode functions (waitForReadyRead() / waitForBytesWritten()) and asynchronous functions (readyRead() / bytesWritten()) is not recommended second: a serial port link is a stream interface and not a packet interface. So you have to know how to detect message begin and end from this stream. When you read data, you may read the full message or just a part of it! So you code cannot work properly! I support your messages ends with $, so you could do something like this: void MainWindow::ReaderH() { // I support m_readData is a QByteArray while(serial->bytesAvailable()) { m_readData.append(serial->readall()); } int idx=0; while( (idx=m_readData.indexOf('$')) >= 0 ) { if(idx > 0) { auto message = QString(m_readData.left(idx)); qDebug() << "Message:"<< message << " \r\n"; } m_readData.remove(0, idx+1); } }

  @bsdillon Gerate, that you managed to make it work! (Correctly) Setting up a pro file is no easy task and often very frustrating. Sometimes I wonder, if I shouldn't just make the change to cmake, eventually it's going to happen. You really should get the credit on stackoverflow. I do have a stackoverflow, account, I made it years ago to thank someone for a solution and to make an upvote. No idea if it's still valid :D

Error while building / deploying project rotortest (kit: Desktop Qt 5.15.0 MinGW 64-bit) When executing step "Make" How can I fix it? My system: Qt Creator 4.12.4 (GCC based - downloaded by MSYS2) Qt 5.15.0 Windows 10 x64 Mingw-w64 jom Should be completely irrelevant. When your make file works with mingw-make, it has to work with jom as well. jomis a replacement for nmake because it did not allow -j parameter. AFAIK the MSVC does support directly multi-threading and it is not done through nmake. Besides possible side effects through parallel access to the same file or whatever, there is no difference for compilation. You are listing compile errors which are due to the compiler you are using. Second question @koahnig said in Build with mingw32-make *very* slow: Mingw-make does support now multi-threading. I did some tests back then, but after a reinstall, there was no need anymore. Are you saying that you compiled your Qt project using the default MSYS2 Mingw-64 configuration (WITHOUT jom) and got a close time compilation speed compared with MSVC 2019? Nope. I do not use MSVC 2019 compiler at all. AFAIK there was an issue with an older MinGW-make not suporting multi-threading. Therefore this discussion and the solution with jom. After my reinstall I did not bother to set up jom again. At day's end some gain is possible by switching to jom, but it was not enough to go through the hassle again. You seem to use a self-compiled Qt creator version. The output shows strange blanks around the backslashes. Possibly there is your problem with compilation.

  Also encountered this very same problem. It's definitely a GDB bug. It even happens when I compile a simple C++ hello world program from the console and then debug it with gdb. As soon as you hit a breakpoint and ask the debugger "info registers" then it's all over. Have created a ticket here: https://sourceware.org/bugzilla/show_bug.cgi?id=26304

  @mzimmers said in possible to copy a kit from one PC to another?: OK, but...tarball what exactly? Tarball your Qt libraries for that kit. And tarball your cross-compiler if the other machine doesn't have it. I only want to copy one of my kits, and it would be nice it I didn't have to go back into Creator and manually update all the settings for that kit. I've never tried to export kit settings from Qt Creator, but the sdktool might do what you want. It comes bundled with Qt Creator, and it's what the official installer uses to register kits: https://github.com/qt-creator/qt-creator/blob/master/src/tools/sdktool/README.md If this is a once-off though, it might be faster to manually update the settings in your new PC.

EmacsKeys 4.12.4 The main idea behind this plugin is to provide additional actions a typical emacs user would expect. It doesn't claim to provide full emacs emulation. The following actions are available: - Movement [C-f, C-b, C-n, C-p, M-f, M-b, C-a, C-e, M-<, M->] - Mark-based selection [C-SPC, C-x C-x] - Cut/copy/yank (doesn't provide kill ring feature) [M-w, C-w, C-y] - Kill actions, which interact properly with clipboard [C-k, M-d, C-d] - Scrolling (half of the screen, keeps cursor visible) [C-v, M-v] - Insert new line and indent [C-j] IMPORTANT: Actions are not bound to any key combinations by default. You can find them under 'EmacsKeys' section in keyboard shortcuts settings. Also it's worth mentioning that EmacsKeys plugin forces disabling of menu mnemonics by calling Qt's qt_set_sequence_auto_mnemonic function with false argument. Many of the english menu mnemonics get into the way of typical emacs keys, this includes: Alt+F (File), Alt+B (Build), Alt+W (Window).

  Because of this post I waited a long time before just now moving to Ubuntu 20.04. I am now: Linux ubuntu-20 5.4.0-40-generic #44-Ubuntu Qt Creator 4.11.0 Qt 5.12.8 I am relieved to say Creator seems as fast as it used to be :) I don't use anything remote. So for anyone reading this, I think it's OK to go ahead with 20.04 + Qt Creator.

  Looks like Cppcheck is now a passive thing rather than something you explicitly run? There's no entry for cppcheck under the analyze submenu, but I'm now seeing cppcheck's output as code warnings, so I'm content.

  @hskoglund OK. I will wait that my computer will be OK to have the latest Windows 10 version. I have the 1909 and the latest is 2004. And i will wait for a new version of Qt. Or i will reinstall Windows and all my softwares, but it takes a long time. And thank you very much for your help. Best regards.
