[BUG]SamplesFrameworkBase has pure virtual function error

[bvanevery]

I'm building CEGUI 0.8.2 on Linux. 98% of it builds but this bug kills the build and prevents "make install". It looks like a trivial error in pure virtual function specification? I have not chased through the .h files to determine the exact problem. The Mercurial repository also has this problem.

Are you using DirectFB?

It is kinda broken right now in CEGUI and we dont know how we will proceed about DirectFB yet... If you dont use DirectFB just deactivate it in CMake explicitly. Otherwise a fix should be easy but i cant test it because i dont use DirectFB and got no Linux work environment set up atm.

Yes it's DirectFB. I got the same error last night. Fix:

Code: Select all

cmake -DCEGUI_BUILD_RENDERER_DIRECTFB=OFF -DCEGUI_SAMPLES_USE_DIRECTFB=OFF
