Hi Geyang,

You are probably compiling with base  3.14.10? There are some (secret) changes
between 3.14.8.2 and 3.14.9 which require some modifications in the source code.
Have a look in gateVc.cc lines 1012-1014. Comment line 1013 and uncomment line
1014.

Maybe I should add some macro tests for EPICS_MODIFICATION, but there are other
problems, eg. when using pre-releases (See my reply on the "sscan compile error
on base 3.14.10 in linux" thread).
