Hi Josep,

Hello,

I am a teacher and I've been user of openSankore, which is an open source software for interactive whiteboards. Previous versions of openSuse had a built package to install through One-click-install. But it seems that openSankore has been left since the newest version is a little bit old. Actually, there is no package for Leap.

Otherwise, I have realized that there is a fork of that project called OpenBoard which has more recent versions. But unfortunately there isn't any opensuse version. They offer the source code to be compiled by yourself which is far from my possibilities.

Is there someone that could do it for me?

Thanks in advance

Josep

I was trying to build OpenBoard for you. I created a OBS project to build it: https://build.opensuse.org/package/show/home:okurz:OpenBoard/OpenBoard

I am getting as far as a compile error which I don't know immediately how to handle.

The compiler error details:

Maybe someone else has an idea how to continue from here.

Have fun, Oliver

Oliver,

A c++ programmer can probably fix (patch) that up pretty quickly, but it would be better to report it to upstream and get them to do a real fix that will be part of the next release. They could probably provide you the needed patch as well will little problem.

Yes, should be reported upstream, but I just checked the Qt docs and qreal is typedfed to double. abs(), according to

http://www.cplusplus.com/reference/cmath/abs/

comes in three flavors. So I don't see why abs(double) is not chosen as the prototype for abs(qreal). But, looking at the error message, it is taking the "usual" C prototype for abs (which is abs(int)). A fix for this until you hear from the upstream maintainers is to use std::abs() instead of abs().

Another option is to include cmath: #include <cmath> to get the C++ prototypes -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
