OpenGLES test project on Android fails to compile

[Metadr]

I did all the configuration steps and provided every directory for jdk, sdk, ant & android ndk.
I'm trying now to compile a simple test project which builds and run fine while compiling it with the desktop compiler but fails on armv7 since "error: OpenGL.so: No such file or directory"

extended error:

here's the source.cpp:

#include "controller.h"

MainWindow::MainWindow(QWindow *parent) : QWindow(parent),
                                          m_context(0),
                                          fmt(new QSurfaceFormat)
{
    setSurfaceType(QWindow::OpenGLSurface);
    //fmt->setRenderableType(QSurfaceFormat::OpenGLES);
    //fmt->setVersion(2,0);
    //fmt->setProfile(QSurfaceFormat::CoreProfile);
    //I'll need later fmt to try and set an alpha buffer on it
    fmt = new QSurfaceFormat(requestedFormat());
    resize(640,480);

    setFormat(requestedFormat());

    m_context = new QOpenGLContext(this);
    m_context->setFormat(requestedFormat());
    m_context->create();
}


void MainWindow::render()
{
    if (!isExposed())  return;
    
        m_context->makeCurrent(this);
        initializeOpenGLFunctions();

        
    QTime t;
    t = QTime::currentTime();
    glClearColor(1, 0.5f, 0, 0.5f);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);


    m_context->swapBuffers(this);
    QCoreApplication::postEvent(this, new QEvent(QEvent::UpdateRequest));
}

Lastly the .pro file:

TEMPLATE = app
TARGET = Android OpenGL

QT += core gui opengl

SOURCES += \
    main.cpp \
    controller.cpp

HEADERS += \
    controller.h

CONFIG += mobility
MOBILITY =

Unfortunately this is the first time I try to build a project targeted for android and it all seems fine while compiling for desktop but it crashes on arm7
Is something missing in the ndk? I don't even know where i'm supposed to place the missing opengl.so nor how to compile it

Hi and welcome to devnet,

I'd remove the space between Android and OpenGL in your TARGET directive.

[Metadr]

Awkward moment of the day I guess

Quick unrelated question: Is it possible to have a format that can make the opengl application's background transparent?

in the desktop it's sufficient to use :
fmt->setAlphaBufferSize(8);
for the desired effect

Anyway, thanks a lot for your help

EDIT: nevermind, I solved it. you only need to change the manifest and apply android:theme="@android:style/Theme.Translucent" to the application tag

Glad you found out and thanks for sharing !

Since you have it working now please mark the thread as solved using the"Topic Tool" button so that other forum users may know a solution has been found :)
