When I run xilinx tool, I open a new cmd window, and source .bashrc_xil, this window only run xilinx tool. The action can solve my problem.

Create a wrapper function/alias/script around your tool which will run

LD_LIBRARY_PATH=/opt/Xilinx/Vivado/2014.3/lib your-xilinx-tool

, e.g. like adding

alias your-xilinx-tool="LD_LIBRARY_PATH=/opt/Xilinx/Vivado/2014.3/lib
your-xilinx-tool"

to the bashrc.

Given the nature of the message you are seeing it is extremely bad
idea to run *anything*, but xilinx tool with that LD_LIBRARY_PATH:
given that they override at least some system shared libraries any
application using overridden libraries may malfunction, not only gvim,
and possibly not only by refusing to work at all.

And I would suggest to contact whoever packaged xilinx tools, I have
seen software like this (coming with their own libs) placed in /opt
and corresponding packages *already come with a wrapper script* which
do exactly that (plus sometimes with more modifications to environment
and/or argument list) without requiring user to modify environment on
their own. But first search your xilinx package for preexisting
wrappers, maybe you are using what you are not supposed to use
directly.
