In gcc 4.3, implicit includes were removed [1].
This patch fixes includes in beagle-4.0.0-alpha1 for compilation with gcc-4.3 and above.
To apply the patch:
%> tar xf OpenBEAGLE-4.0.0-alpha1-Source.tar.gz
%> cd OpenBEAGLE-4.0.0-alpha1-Source
%> patch -p0 < ../OpenBEAGLE-4.0.0-alpha1-Source-gcc43.patch
The above assumes that OpenBEAGLE-4.0.0-alpha1-Source-gcc43.patch and OpenBEAGLE-4.0.0-alpha1-Source.tar.gz reside in the current working directory.
