CMake error: graphicswindow.cpp

[y4my4my4m]

I've installed the dependencies and am met with this error when trying to build:

Any advice?

I'm using arch linux. The dependencies/gcc are all recent/latest versions.

Seems that this is no longer how things are done with OSG 3.4/3.6 (I can reproduce this error with OSG 3.6)

[y4my4my4m]

@psi29a I've tried to manually build OSG 3.2 but alas...seems like it coincidentally has a build problem specifically on arch linux.

Let me know if there's an easy fix for OSG 3.6. I'd love to try this out.

[psi29a]

Sadly no quick fix that I found. Even OpenMW does things slightly different here.

[y4my4my4m]

@psi29a I'm not too sure how I did it but I got it to build on OSG3.6

I deleted MYGUI_DBG_BREAK; from src/components/mygui_sg/diagnostic.h and it seems to have helped.

This is hacky, but figured I'd leave it as a comment in case someone stumble upon this issue later on...

[psi29a]

You must have done something else, as doing that for me doesn't change this:

/home/psi29a/workspace/opendf/src/components/sdlutil/graphicswindow.cpp: In function ‘void SDLUtil::graphicswindow_SDL2()’:
/home/psi29a/workspace/opendf/src/components/sdlutil/graphicswindow.cpp:312:27: error: ‘setWindowingSystemInterface’ is not a member of ‘osg::GraphicsContext’
     osg::GraphicsContext::setWindowingSystemInterface(new SDL2WindowingSystemInterface);
                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Are you sure it is OSG 3.6 and not 3.2 or 3.4 ?

[y4my4my4m]

@psi29a yes, the difference that I can see is that I did try to build 3.2 manually from cloning the source code on the branch 3.2... (git clone --branch OpenSceneGraph-3.2.3 https://github.com/openscenegraph/OpenSceneGraph.git)

but I never made it past make (couldnt get to make install as make would flood with errors around 30% in) so it would make no sense this helped...right? Unless it installed some dependencies without me noticing?

3.6 was completely uninstalled at this point, after 3.2.3 failing, I reinstalled 3.6 using pacman

I made it work with the current OpenSceneGraph. Fixes are in this PR https://github.com/kcat/opendf/pull/16
