Experimental Physics and
Industrial Control System

Hello,

I'm having problems with inistalling EPICS on Ubuntu Linux. I've downloaded EPICS Base R3.14.10 and update GNU make to 3.8.1. I've not installed the GNU readLine library, so I  have  commentted out COMMANDLINE_LIBRARY=READLINE in configure/os/CONFIG_SITE.Common.linux-x86. 

I've set the environment variables in .bashrc:
export EPICS_HOST=linux-x86
export EPICS_HOST_ARCH=linux-x86
export EPICS_BASE=/usr/local/epics/base
export EPICS_EXTENSIONS=/usr/local/epics/extensions
export PATH=$PATH:$EPICS_BASE/bin/$EPICS_HOST_ARCH

base compile successfully!

Then I've created an example application in the "iocapps" directory:
  

cd /usr/local/epics 
mkdir iocapps 
cd iocapps/
/usr/local/epics/base/bin/linux-x86/makeBaseApp.pl -t example dcct
/usr/local/epics/base/bin/linux-x86/makeBaseApp.pl -i -t example dcct
make 
cd iocBoot/
cd iocdcct/ 
../../bin/linux-x86/dcct st.cmd
#!../../bin/linux-x86/dcct
## You may have to change dcct to something else
## everywhere it appears in this file
< envPaths
epicsEnvSet("ARCH","linux-x86")
epicsEnvSet("IOC","iocdcct")
epicsEnvSet("TOP","/usr/local/epics/iocapps")
epicsEnvSet("EPICS_BASE","/usr/local/epics/base")
cd /usr/local/epics/iocapps
## Register all support components
dbLoadDatabase "dbd/dcct.dbd"
dcct_registerRecordDeviceDriver pdbbase
## Load record instances
dbLoadTemplate "db/userHost.substitutions"
dbLoadRecords "db/dbSubExample.db", "user=xyHost"
## Set this to see messages from mySub
#var mySubDebug 1
## Run this to trace the stages of iocInit
#traceIocInit
cd /usr/local/epics/iocapps/iocBoot/iocdcct
iocInit

I open another terminal on the same computer

xy@linux:/usr/local/epics/base/bin/linux-x86> caget xyHost:aiExample2
Channel connect timed out: 'xyHost:aiExample2' not found.
xy@linux:/usr/local/epics/base/bin/linux-x86> camonitor xyHost:aiExample2
xyHost:aiExample2              *** Not connected (PV not found)

I do not know why(PV not found)?Any idea what could be wrong, and how to solve it?

Thanks

Horald
