I found another error please help

Then run configure with the -v option to see what failed when checking for xkbcommon.

Hi, I'm currently using ArcGIS SDK and I can not even make the default projects work. I had some dll problems I coulded solve putting them into the proyect library, but for some reason QtQuick.Controls fails on load. When i try to run the app, i have this error in the application output window

@vaibs In your other thread you already was told to simply install Qt 4.8.7 provided by Ubuntu! Why don't you do so?
Qt 4.8.7 is 100% compatible to 4.8.1 (the last number in the version number is simply an indicator for bug fix releases).

Hello

I am fairly new to Qt and trying to install version 4.8.6 open source on Ubuntu 18.04 LTS to run other simulations. I have been successful before in installing it on 16.04 LTS but now I have received the following error during installation:

/usr/include/openssl/ossl_typ.h:107:16: note: forward declaration of ‘DSA {aka struct dsa_st}’
typedef struct dsa_st DSA;

Can anyone please help?

Thanks in advance

@sierdzio yes it does build on the local PC , i'm attaching the screenshots of before and after build from my local system

Some time ago I set up a Linux host to cross-compile Qt5 for RPi3. I used this configure command:

./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/opt/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot ~/opt/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/opt/qt5pi -hostprefix ~/opt/qt5 -v -nomake examples -nomake tests -reduce-exports -no-pch -no-use-gold-linker

and I successfully cross-compiled Qt5.9 with EGLFS support. Now I want update to Qt5.13.
Today, I checked out the git repository and typed the same configure command. Here the configure output:

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

I don't understand why the OpenGL has failed this time. Perhaps I need to install some other libraries? When cross-compiling I always confused if I need to install library for my host on for the target... As side note, it's correct the specified device? I see other people use -device linux-rpi3-vc4-g++ (I want hw acceleration for omxplayer).

Dear folks,

I am trying to build binaries for Qt including SQL drivers for deployment, using mingw 8.1.0 and Qt 5.12.

Hi and welcome to devnet forum

This is only a user's forum. Nobody is monitring for bug reports and implementation suggestions. You would need to make an input to JIRA which is the offical bug tracker for Qt and all tools. You may use your account credentials also there.

In documentation, the Qmqtt namespace has been oficially added on 5.12 version.
https://doc.qt.io/QtMQTT/qmqtt.html
But this module integration was discussied in old threads in this forum
https://forum.qt.io/topic/87330/how-can-i-add-module-mqtt-to-qt

@gzhang did you find out how to fix this?

I tried running the browser and got a message stating:

An error occurred while opening the connection: Authentication plugin 'caching_sha2_password' cannot be loaded: The specified module could not be found. QMYSQL: Unable to connect

Hi everybody ! I just installed Qt 5.11.2. And now I want to add some other components of Qt and also the Felgo framework (it is. qml-based framework) to it via the maintenance tool !

But there is not any repository when i click on settings in the qt maintenance tool !

Please help me. I have to release my app next week !

Perhaps some dll files are missing.

Dear folks,

I am trying to build Qt 5.12 with documentation and examples for MinGW Windows, but am despairing because the output directory does not contain the "doc" folder content.

Here is how it is being built:

REM NOTE: src32 path was used in 5.12 because of a gcc compiler bug that prevented compilation on x86 in qrandom.cpp

set SOURCES=D:\temp\src32
set OUTPUT=D:\Libs\qt\5.12\mingw64\x86

set LLVM_INSTALL_DIR=C:\Program Files (x86)\LLVM
set PATH=C:\Program Files (x86)\mingw_w64_posix_sjlj_8_1_0\bin;%LLVM_INSTALL_DIR%\bin;%PATH%


SET PATH="C:\Python34_x64";%PATH%

mingw32-make.exe -j 4
mingw32-make.exe -j 4 module-qttools
mingw32-make.exe -j 4 docs
mingw32-make.exe -j 4 install

Now, the src32\qtbase\doc directory contains data: qch files, but the output (prefix/install) directory "doc" subfolder only contains a "global" folder.

Any ideas / am I missing something not described in https://wiki.qt.io/Building_Qt_Documentation ?

@AndyBrice
did you really install 140gb worth of precompiled Qt?

I highly doubt you need all those version

I've used 5.9 without problems.I can't compile Android projects, because has a configuration error:

"No compiler can produce code for this Qt version. Please define one or more compilers for:arm-linux-android-elf-64bit,x86-linux-android-elf-64bit,"

I downloaded qt-everywhere-src-5.12.3.tar.xz, extracted and configured with

OPENSSL_LIBS='-L/usr/lib/x86_64-linux-gnu -lssl -lcrypto' $SRC_FOLDER/configure -release -opensource -confirm-license -prefix $PREFIX_FOLDER -openssl-linked -static -optimize-size -ltcg -nomake examples -nomake tests -nomake tools -skip qtwebengine -skip qtdeclarative

It seems to finish just fine but when trying to build a project I get

Project ERROR: Unknown module(s) in QT: x11extras

The only relevant part that happens during make is

cd qtx11extras/ && ( test -e Makefile || /home/skyweb/Qt/5.12.3/64_static-build/qtbase/bin/qmake -o Makefile /home/skyweb/Qt/5.12.3/qt-everywhere-src-5.12.3/qtx11extras/qtx11extras.pro ) && make -f Makefile install

I'm struggling to build and use Qt for Wasm on the new 5.13.0-beta2.
I'm running on windows, my configure looks like

configure -no-warnings-are-errors -xplatform wasm-emscripten -platform win32-g++ -nomake examples -prefix $PWD/qtbase -feature-thread -skip qt3d -skip qtcanvas3d -skip qtcharts -skip qtconnectivity -skip qtdatavis3d -skip qtwayland -skip qtwebchannel -skip qtwebengine -skip qtwebview -skip qttools -no-dbus -no-zlib -skip qtxmlpatterns

after which I just mingw32-make and try to apply the resulting qmake in qtbase/bin to my project.
This results in Project ERROR: Unknown module(s) in QT: websockets when encountering any .pro that uses QT += websockets.

Investigating, I see there are no library files corresponding to libQt5WebSockets in qtbase/lib. The qtwebsockets directory is being processed by make, the built library files are present in the qtwebsockets directory, but don't seem to get copied to qtbase/lib.

(mingw32-make install doesn't do this either - it seems to copy things to a 'WD' directory instead? I was under the impression that install wasn't a meaningful part of this process on windows anyway, it's not included in the qt-wasm examples.)

Copying the library files manually into qtbase/lib seems to have no effect - qmake fails with unknown module(s) whether they are present or not. Am I missing something huge here regarding the use of optional modules?
