Hi,
Thank you Lukas for looking at my problem.
The LSS-version of Nightshade is a clone of the official Nightsade version
+ keyboard shortcuts which can launch scripts, videos and music.
Each key of the 105 keys has a special function and it is specially
designed for a planetarium public show.
With bluetooth modules, we can drive the show with a Nintendo Wii remote ;
very useful.
http://www.lss-planetariums.info/index.php?lang=en&menu=hardware&page=keyboard
I tried to compile Nightshade-LSS on Ubuntu-12, Linux Mint and Mageia2 via
VirtualBox and i get exactly the same errors.
So, i think it is not a Gentoo problem...but nevertheless very annoying :-(
I looked at the Nightshade-LSS sources and it seems that the error occurs
with the nshade_shared_memory.h and nshade_shared_memory.cpp in
~/nightshade-11.7.1/nscontrol/src
I join the two files ; may be these files would help us.
Thank you very much,
