Hello,

I'm having problems with inistalling EPICS on Ubuntu Linux. I've
downloaded EPICS Base R3.14.10 and the following modules:  Asyn,
drvIpac and Sequencer compiler 2.0.11. These were all compiled ok.
I've also installed the GNU readLine library, so I didn't have to
comment out the line in the config file.

So it all compiled fine, I've set the environment variables in .bashrc:
export EPICS_CA_ADD_LIST=127.0.0.1
export EPICS_ROOT=/opt/epics
export EPICS_HOST_ARCH=linux-x86
export EPICS_BASE=$EPICS_ROOT/base
export EPICS_EXTENSIONS=$EPICS_ROOT/extensions
export PATH=$PATH:$EPICS_BASE/bin/$EPICS_HOST_ARCH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$EPICS_BASE/lib/$EPICS_HOST_ARCH:$EPICS_EXTENSIONS/lib/$EPICS_HOST_ARCH:$EPICS_APPS/lib/$EPICS_HOST_ARCH

Then I've created an example application in the "work3" directory:

makeBaseApp.pl -t example myexample3
makeBaseApp.pl -i -t example myexample3

It all worked fine, I wrote "make" and the application was built.
However, when I started the application, it didn't work fine. It says
for example "unknown type ai" and "unknown type calc". I'm guessing it
cannot find the database. This is the complete output:

user@ubuntu-vmware:~/work3/iocBoot/iocmyexample2$

Any idea what could be wrong, and how to fix it?

Thanks, Csaba
