Installation and Deployment

@koahnig , thanks a lot for your tips. I installed qt again . using an other guide It worked almost with some changes. The timer problem I solved by adding -lrt to the make. The problem using the assignemend : tidp = &si->si_value.sival_ptr; I solved in this "old style" way; titp = (void**)si->si_value.sival_ptr; It works now.

opengles3 support has not yet been enabled. See this change: https://codereview.qt-project.org/c/qt/qtbase/+/225310 As well, I am not sure you want to add -eglfs and -xcb, as these platform plugins are not used in wasm platform. Not exactly sure -glib will gain you anything in particular, but it is not needed for wasm. Please do let me know if you run into opengles3 issues! https://bugreports.qt.io

@scooter1556 Thank you for your post! Had wrong classification results all the time, now everything is working fine. I stumbled upon this thread some weeks ago already. Luckily I checked for updates again today :)

@j-hilk this is a linux mint error, I solved this by compiling on ubuntu

Ah, it's the linker where the problem is, adding -Wl,-rpath-link,/lib/64,-rpath-link,/usr/X11/lib/amd64 to QMAKE_LFLAGS fixes the problem. Edit: This problem arose by using a custom GCC compiled to link with /usr/bin/gld (GNU ld) supplied by Oracle. The GNU ld seems like it doesn't look for shared library dependencies in the right folders, so it has to be explicitly told to do so (the folders I specified aren't all that are missing, adding /usr/lib/64 and /usr/lib/amd64 seems to fix even more libraries.)

@mzimmers pusillanimous ... insouciant in contrast to persiflage, I actually had to look those to two up!

Thank you for reply. Normally the app shoud run correctly on a local Qt environment PC, even outside Creator. I have uninstalled Qt with uninstall tool and reinstalled it again, and the problem no longer appears

@pablo-j-rogina , RPi 2, i just passed that problem and I have another one. After sudo make install I get multimple Makefile recipe for target '...' failed, what could be the problem?

Thanks for your reply. I just tried and obtained the same result.

If I add into my <pro file dir>\.. folder some junctions to %QTDIR%\bin, %QTDIR%\mkspec, %QTDIR%\plugins, and %QTDIR%\translations, windeployqt stops complaining and finishes successfully. This hack is the only thing that's worked so far -- even hacking PATH doesn't work.

ok i'll ask him to reinstall it once again

Hi, How can I do it? Should I make a change to some qt recipe? In Yocto build dir I can see -staticdev ipk packages: build@c9cafac50b9b:~/shared/yocto/poky/build$ ll tmp/deploy/ipk/cortexa9hf-neon/qt*-staticdev* | wc -l 21 How can I tell bitbake to include these packages into toolchain install script?

@oswaldopr said in File not recognized: File format not recognized error: I’m trying to complie in my raspberry pi, and the same error appears, I’m using a dynamic library (.so) You need to be sure the .so file you're using is for the right platform (i.e. ARM)

Hi and welcome to devnet, This is an issue you should bring to the linuxdeployqt developers. You might be one if not the first building such a use case. I would recommend making a simple project that reproduces this, that will help the developers see what's going on.

@Dmitriy-Shmykov did you find out a way to do it? Thanks

Yes, the Qt offline installers are one-shot, you can't update the installation. There exists a ticket for this kind of feature but currently there are no plans to implement it. https://bugreports.qt.io/browse/QTIFW-1281

Hi @Saikumar123 , could you share more details about the issue and preferably open a bug ticket here: https://bugreports.qt.io Which host OS are you using (32/64bit?, OS version etc.). Are you using Qt Online or offline installer? Which version? Are you behind a proxy or firewall?

Hi @Malathi-K I'd recommed to use the Qt Online installer. With that you can install latest Qt packages and the QtCreator as well. The installer will automatically install Kits (registers compilers and debuggers) and in addition it will contain the examples and documentation of the selected Qt packages: https://download.qt.io/official_releases/online_installers/
