Installation and Deployment

I t seems to be work now. I need to perform the same path replacement in .cmake, .pri, .pc and .prl with "/" and "\" where the libs are added with the mingw hardcoded path.

You should be able to build it but there might be some warnings you might have to take into account. As for the oldest version, you'll have to test. If not working as you want, you have the option of using Parallels and build on an older version of macOS and Xcode.

Hi and welcome to devnet, While I understand your frustration, please do not post the same question in multiple sub forum. Duplicate Closing this one

@nen777w said in Qt 5.15.2 do not build libqxcb.so, BUT at the same time Qt 5.14.0 successfully build libqxcb.so: It required for build Qt 5.15.x but not required for Qt 5.14.x Correct as described here: https://doc.qt.io/qt-5/linux-requirements.html Note: From Qt 5.15 onwards, Qt does require libxcb 1.11. Also, the -qt-xcb configure option got removed that was bundling some of the libs below. Anyhow, you can now configure with -bundled-xcb-xinput to avoid a dependency to system xcb-xinput.

The problem seems to stem from qglobals.h including qconfig-boostrapped.h when building qtbase/src/tools/boostrap, instead of the generated qtcore-config.h. This file does not define QT_POSIX_IPC, and thus tries to build qsystemsemaphore_systemv.cpp. I'll post a bug report.

@LionTeFromGuernsey said in Qt 5.8 Installation and Qt Creator launch issue: ~/Qt $ sudo apt-get install xcb # DOES NOT SOLVE THE PROBLEM! That does not solve the problem because XCB is not missing You need to find out which dependencies are missing. Run ldd on plugins/platforms/libqxcb.so and install the libraries that are marked "not found".

@JonexElectronic said in How to Install QT Creator 4.2.1 Based on Qt 5.8.0 (GCC 5.3.1) ?: @sierdzio I tried but I couldn't find the Qt version 5.8.0 and also i dont know how to install separately. Because, I have few projects in this version and I don't want to have any compatibility problem. But you asked about Qt Creator, not Qt. So look for "4.2" under: https://download.qt.io/archive/qtcreator/4.2/ If you have meant to ask about Qt, use the link @Christian-Ehrlicher provided. Qt Creator has nothing to do with it.

@jeremy_k yes, I have copied all the dependencies, used windeployqt for this. btw the issue is resolved now, 3D graphics was disabled for the VM, which was not allowing Application to render required graphics. Thanks @jeremy_k :)

In my case, the examples only show up when I run "sudo qtcreator". The problem now is how to make them show up without "sudo".

Hi, You can't. They are part of the repositories themselves.

Run ldd on your binary file (before deployment) to see what it is really linked against.

@aamp QtWebEngine and emscripten?! What are you trying? Running a webbrowser inside a webbrowser? https://doc.qt.io/qt-5/qtwebengine-platform-notes.html

@jsulm Yes I download it from https://www.qt.io/download using "Downloads for open source users". By the way, using the same installation, I choose Qt5.15 and now I am able to create QtQuick projects.

Hi, See this stack overflow answer for a possible way to do it. If it does not work, then you might as well just the open the files in the browser and copy their content.

Either by passing the -platform argument to your application or using the QT_QPA_PLATFORM environment variable.

@mrjj thanks for your reply which fonts shoud I install please

Hi and welcome to devnet, Since this guide is for Qt 5, switch your clone branch to Qt 5.15. The default branch on clone is dev which is for Qt 6.

Hi, The developer-build option is for people wanting to hack on Qt itself so it should not be used for deployment purpose nor development other than Qt itself. IIRC, there are some difference in the set of options and flags used for the compilers. It's an "in-place" build so there's nothing to install.
