Any prebuild version of 5.1(mingw4.8 32 + angel)



  • Can't find angel version on the download page
    "downloads":http://qt-project.org/downloads

    Do anyone have a prebuild Qt5.1 of mingw4.8 32 + angel?
    Any plan to release a prebuild version on next release(5.1.1 or 5.2)?

    There seem to be a contradiction since the note below the sdk downloads says:

    The Windows offline installers are by default ANGLE based. If you want to know more about the differences between ANGLE and OpenGL packages on Windows, please visit Qt 5 on Windows ANGLE and OpenGL.

    Did you check the online installer?

    Haven't tried it yet, but I wonder it would provide a different version
    or not?I will give it a try and tell you the result

    bq. The Windows offline installers are by default ANGLE based.

    I am sure that the offline installers of mingw is openGL based but not ANGEL

    Qt 5.1.0 for Windows 32-bit (MinGW 4.8, OpenGL, 666 MB) (Info)

    This don't look like a ANGEL based for me

    The online installer says:
    @
    msvc2010 32bit
    msvc2010 32bit with OpenGl
    msvc2012 64bit
    msvc2012 64bit with OpenGl
    MinGW 4.8 (32bit)
    @
    no mentioning of OpenGL for MInGW though.

    The version installed with online installer has QtOpenGL.dll. Is there another way to check?

    The method I use is very rough, "read and show the jpg by Image"

    @
    import QtQuick 2.0

    Rectangle {
    width: 100
    height: 62

    Image{
        anchors.fill: parent
        fillMode: Image.PreserveAspectFit
        source: "file:/Users/xxxx/Downloads/1320561238261.jpg"
    }
    

    }

    @

    The msvc2012 ANGEL based could show the image without any problem but the mingw can't

    I installed it by oneline install tool and give it a try but have no luck to read the image either

    my laptop is lenovo G770, if your windows are same as mine
    do not have decent support for openGL than this simple test should work for you

    I am using qwt, which requires OpenGL dll, but that is all I know. I do some graphs with qwt and that is it.

    My desktop uses Qt 5.1.0 MinGW all from online installer and my laptop has been installed with offline installer IIRC.

    The "funny" issue I had lately was that my installation are somehow not directly interchangable. I tested in the release folder that I can start the app with all the required dlls from command line (Qt eliminated from path env var). However, it did not work on laptop. Even though both have Win7 64 bit and both have Qt 5.1.0 installed as described above. This occurs only when I have GUI in my application. With CoreApplication I could exchange. That way I found out about the platforms plugin. Do not know if this helps.



  • Thanks for your helps :)

    I am sure that the Qt of mingw is based on OpenGL because my laptop
    do not have decent support for openGL, maybe update the driver could
    solve the problem, but this do not mean the programs could run on other
    win7 machines without update their driver.

    A "bug" report on jira
    "provide angel for mingw":https://bugreports.qt-project.org/browse/QTBUG-32270?page=com.atlassian.streams.streams-jira-plugin:activity-stream-issue-tab

    I don't know why, but since Qt5.1, they prefer to release prebuild openGL version rather than ANGEL version.
    Maybe ANGEL version have some bugs?
    If there are no plan to provide a prebuild ANGEL version, than I have no choice but try to compile Qt5.1.x(or Qt5.2) by myself(not a trivial task for me).

    Hello ! Ihave installed via Online Installer "MinGW 4.8" and I've used "Dependency Walker"(free windows program) on my fresh compiled app (On Qt5.1.1): It says it's "using OpenGL":http://cl.ly/image/0x3e3q1o3G0B

    :/

    Yep, that is the point of the discussion.
    Even so ANGLE compilation is referred to as default, it is not for MinGW. It is only true for msvc compilations.
    For the offline installers it is apparently declared correctly that there is only an OpenGL version available. The declaration in the online installer is misleading.
    Note: checks above are done with Qt 5.1.0 installations. However, it may be the same with Qt 5.1.1.

    I've edited my post, actually I'm on 5.1.1, so same same.
