[Solved] Qt everywhere 5.3.2 source compile failure on beaglebone black with -DQT_NO_DEBUG_OUTPUT

pgregory

I'm planning on developing beaglebone debian 7.6 applications on a beaglebone black using Qt 5.3.2
I compiled the qt everywhere 5.3.2 open source library fine on the beaglebone with the following configure options

configure -v -opensource -confirm-license -prefix /usr/local/qt-5.3.2 -no-largefile -qt-zlib -qt-libpng -qt-libjpeg -no-nis -no-cups -opengl es2 -qt-xcb -qt-freetype -qt-xkbcommon -no-kms -v

And it compiles and works fine.
However, the terminal is overrun with debugging messages and it runs very slow.
I attempted to turn off the debugging messages using the option:

configure -v -opensource -confirm-license -prefix /usr/local/qt-5.3.2 -no-largefile -qt-zlib -qt-libpng -qt-libjpeg -no-nis -no-cups -opengl es2 -qt-xcb -qt-freetype -qt-xkbcommon -no-kms -v -DQT_NO_DEBUG_OUTPUT -DQT_NO_WARNING_OUTPUT

Now it compiles until it reaches qtdeclarative/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:

src/qtdeclarative/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:256:20: error: expected primary-expression before 'while'

It bombs out trying to compile the line

    QDebug d = qDebug();

I'm compiling with gcc version 4.6.3-14

Any ideas on how to get the compile to work?
Or another way to disable debug and warning console messages?

Hi and welcome to devnet,

There's a patch pending for 5.4 for that problem.

In between you can comment the offending code since it's all debugging related and you don't seem interested

Commenting out the code that uses QDebug in a manner that throws exceptions when debug messages are turned off works.
I successfully compiled the code with -DQT_NO_DEBUG_OUTPUT -DQT_NO_WARNING_OUTPUT.
It runs without messages output to the console window.

Patch got in, so you'll be fine when 5.4 RC comes out
