I have not had any luck building YAC on Ubuntu 15.10.

Ideally, I would prefer to run the headless library server version, but for now, I was just trying to build the GUI version with the "no_opengl" option.

The odd thing is that I think "qmake CONFIG+=no_opengl" still results in a build that looks for OpenGL?

If I run it over VNC it crashes with a "Could not initialize GLX" error.

If I run it directly on the machine, the initial screen launches then freezes with the following log:

Any ideas?

Hi max6166,

the no_opengl config option is intended for embedded systems that only support embedded OpenGL. It removes hard dependencies on desktop grade OpenGL. Since the Qt toolkit itself makes use of OpenGL for other stuff we can't remove it completely. So it's probably not what you're looking for ;)

I'm not sure what exactly happens in your build of YACReaderLibrary. QOpenGLWidget shouldn't be used with the no_opengl option. I'll have to setup a 32 bit virtual machine to test it - after the holidays.

P.S: Since you feel comfortable building YAC* yourself you might want to contact Luis regarding the headless version. It's still very much a work in progress (alpha or pre-alpha), but he might be interested in having a tester or two who are skilled enough to compile the code themself ;)
My answers are not necessarily official YACReader statements but mostly represent my own opinion in technical matters.
