[1] Check whether a plain libstdc++.so is installed/avail.
On Debian, if installed the dev packages, e.g.
libstdc++-4.9-dev:amd64
lib32stdc++-4.9-dev
you will have the following standard symlinks:
/usr/lib/gcc/x86_64-linux-gnu/4.9/libstdc++.so -> ../../../x86_64-linux-gnu/libstdc++.so.6
/usr/lib/gcc/x86_64-linux-gnu/4.9/32/libstdc++.so -> ../../../../../lib32/libstdc++.so.6
which allows usage of '-lstdc++' at compilation!
+++
[2] Disable OVR:
ant -Dc.build.oculusvr.skip=true ...
+++
Hope it helps.
