@Saman19 said in Qt on MarsBoard, Cross compile error, Socket can fd:

Note: QtSerialBus: Newer kernel needed for flexible data-rate frame support (canfd_frame).

It does not seem to me a problem but an informative note.

If you do not use CAN, check:

Is Kernel Network CAN enabled? Something like: Networking support ---> <M> CAN bus subsystem support ---> --- CAN bus subsystem support <M> Raw CAN Protocol (raw access with CAN-ID filtering) <M> Broadcast Manager CAN Protocol (with content filtering) CAN Device Drivers ---> <M> Virtual Local CAN Interface (vcan) <M> Platform CAN drivers with Netlink support

Mandatory, because under the kernel is the SocketCAN that handles this.

Install the can-utils package

It is necessary to include / install QtSerialPort, not for CAN but for ModBus that is part of QtSerialBus.

I'd recommend using https://doc.qt.io/qt-5.10/qxyseries.html#replace-5

Replacing points one by one destroys a cpu. The metrics for me was just not even worth measuring - it was just an immediate hell no - forget that - I need faster updates. I like declarative QML for gui as a preference but calling replace on a single point fires way too many signals and takes way too long.

I throw my QML LineSeries to a QXYSeries and call replace in c++

In the future I'll probably just declare my series in C++. I wish I could have a better supported hybrid of c++ and QML charts but I have this working very fast using useOpenGL : true; (you can also c++ setUseOpenGL(true) )

@SGaist That an excellent idea! I've sent to interest@qt-project.org. Hope someone could save me.

Ok. I have found the issue.

Since QT5_WRAP_UI macro is delivered as part of Qt5Widget packacge it is necessery to make a call to find_package (Qt5Widget) before issuing QT5_WRAP_UI call.

Ehh :D

Oh dear, you're absolutely right. I was completely overdoing it.
In that case, I must only check for the language files to be present.

Hi Jamie,

Could you put the relevant parts in a minimal compilable example?

otherwise we only can guess...

Hi!
Another option (but also QML only) is the AppDrawer available with V-Play Engine.

It is also possible to use the Navigation type to create a menu that uses a drawer on Android and a tab-bar on iOS.

For example like this:

import VPlayApps 1.0 App { Navigation { NavigationItem { title: "Home" icon: IconType.home NavigationStack { Page { title: "Main Page" } } } NavigationItem { title: "Lists" icon: IconType.list NavigationStack { Page { title: "Lists" } } } } }

Best,
GT

@prithiviraj Something like this could happen because of virtual coordinate system, http://doc.qt.io/qt-5/highdpi.html. Test with Qt::AA_EnableHighDpiScaling and Qt::AA_DisableHighDpiScaling and see what happens.

@SGaist New output (after getting logged out): https://pastebin.com/yJK4tFeQ

Output of diff dmesgOutputBeforeLogout.txt dmesgOutputAfterLogout.txt: https://pastebin.com/5jGtEiUd (differences between two outputs)

It looks like it's searching for the 56 version.

I'm not sure whether the official package comes with a bundled version but I think so. Can you check that ?

Hi everyone!

I'm found the solution of my problem with cross compilation on OS X. The solution is MXE.

Here is script to install:

#install all need tools using home brew. brew install autoconf automake coreutils gdk-pixbuf gettext gnu-sed gnu-tar intltool libtool p7zip wget xz #install scons tool ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null brew install scons mkdir mxe && cd mxe #install mxe git clone https://github.com/mxe/mxe.git . export PATH=$PATH:/usr/local/opt/gettext/bin #install qt 5 for windows 32 bit by default. make EXCLUDE_PKGS='gsoap' qt5

After install you will need to add compiler to QtCreator. Also add path to MXE bin folder:

<path_to_mxe_foler>/usr/x86_64-apple-darwin16.1.0/bin <path_to_mxe_foler>/usr/bin

Thats it!

Now I test it on my project and let you now about results.
