Qt5 with Mesa libraries on arm board

Dharani.R

Hi All,

  I have successfully compiled the Qt5 with Mesa libraries, but am facing below error while running the opengl based example code on arm board (No hardware acceleration).

./hellogl2 -platform eglfs

QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
Could not initialize egl display
Aborted

#./hellogl2 -platform linuxfb
QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
QOpenGLWidget is not supported on this platform.

I used below configuration to cross-compile the both Qt5 and Mesa on ARM board:

./configure --disable-glut --with-demos= --with-gallium-drivers= --enable-shared-glapi --enable-gles1 --enable-gles2 --with-driver=dri --disable-gallium-intel --disable-gallium --with-dri-drivers=swrast --with-gallium-drivers=swrast --disable-glx --with-egl-platforms=drm,fbdev

./configure -release -force-pkg-config -opensource -system-zlib -shared -no-separate-debug-info -confirm-license -no-pch -no-c++11 -no-xcb-xlib -no-strip -opengl es2

Please let me know how to enable and test the EGL driver (Mesa) on Qt5.

hello,I have recently encountered the same problem. Although you discovered this problem a few years ago, I would appreciate it if you could answer me!
