Experimental Physics and Industrial Control System
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).
