Cross-compiling Qt Embedded 5.5 for Raspberry Pi 2

[Heinrich]

Hi I need help

I’m using the following tutorial http://visualgdb.com/tutorials/raspberry/qt/embedded/

But at step 16 I get the following error
<div>The OpenGL ES 2.0 functionality test failed!</div>
<div> Use of pkg-config is not enabled, maybe you want to pass -force-pkg-config?</div>
<div> You might need to modify the include and library search paths by editing</div>
<div> QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in</div>
<div> c:/download/qt-everywhere-<wbr />opensource-src-5.5.0/qtbase/<wbr />mkspecs/devices/linux-ras</div>
<div>p-pi2-g++.</div>
<div></div>
<div>I have done everything to the letter please help me</div>

Hello,

 

I have exactly the same problem. My OS is Windows 10 64 bit and I follow the same tutorial.

Hi man,

I found a work around to compile qt5 on the Pi, with visualdbg. Hopes this helps

1. Download new VisualGDB (windows machine)
2. sudo apt-get update (on pi)
3. sudo apt-get install qtdeclarative5-dev (on pi)
4. edit \etc\ld.so.conf (reference https://sysprogs.com/w/fixing-rpath-link-issues-with-cross-compilers/)

/opt/vc/lib

/lib/arm-linux-gnueabihf
/usr/lib/arm-linux-gnueabihf

/usr/local/lib

1. Now in visual studio start new Linux project
2. Use Qt
3. Project template = A QT-based application
4. Build the project locally with cross-compiler
5. Synchronize headers and libraries add /opt and /etc
6. Configure QT settings =

Qt version 5.x

MKspecs directory /usr/lib/arm-linux-gnueabihf/qt5/mkspecs

Should work, let me know

Hi All,

Normally you don’t need to install any new packages on your Pi as long as your ld.so.conf is set correctly and the /opt/vc directory is synchronized.

We have added troubleshooting instructions to the step 16 of the tutorial: http://visualgdb.com/tutorials/raspberry/qt/embedded/

Let us know if you run into further problems.
