[Interest] Shader Program Linker error

[Ramakanthreddy_Kesireddy]

Hi,

am pasting the complete error here when I try to run sample video using Mediaplayer. Same error is being observed for the qtdeclarative scenegraph example.

libEGL warning: use software fallback
Qt at-spi: error getting the accessibility dbus address:  "The name org.a11y.Bus was not provided by any .service files"
Accessibility DBus not found. Falling back to session bus.
Module 'QtMultimedia' does not contain a module identifier directive - it cannot be protected from external registrations.

Hi,

The OpenGL version string: 4.2.0 NVIDIA 302.26 on target.

Does the below shader program error related to bug QTBUG-18529<https://bugreports.qt-project.org/browse/QTBUG-18529>?

Thanks and Regards,
Ramakanth

Hello,

We build Qt5 natively on tegra3 target board.

However, when I try to compile the sample example as mentioned below in qtdeclarative, it gives error
QOpenGLShaderProgram::uniformLocation( qt_Matrix ): shader program is not linked and
couldnot create shader program.

/qt-everywhere-opensource-src-5.0.0/qtdeclarative/examples/quick/scenegraph/openglunderqml

Please let me know what could be the issue on the target.



Thanks and Regards,
Ramakanth
