Re: [Libmesh-users] rpc/rpc.h usability and other problems

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I've found that notation "--enable-2D-only=no" makes library to be
configured with 2D-only option, because, after manual assignment of DIM in
libmesh_common.h there was errors in compiling - redefining.
So, now I've eliminated this line and the library works good finally.
As to the rpc.h problem, I'm going to use ASCII variant - xda, because I
have no ideas how to fix it, and think that this change will not effect
productivity too much, main procedures take more time.
Thank you for quick help!

Regards,
Dmitry.
