Delta Tau Power PMAC EPICS Device Support Manual

8 February 2013

Also update the line that defines the location of your EPICS installation. For example

EPICS_BASE=/usr/lib/epics

Save any changes and exit. cd back up to the top level and then into the application

source directory.

cd ..

cd powerPmacApp/src

It is also necessary to edit the Makefile in that source directory to ensure it points to

the correct installation location of libssh2. In the Makefile there is a variable

ssh2_DIR that should be set to the location of the installed library file. For example

ssh2_DIR = /usr/local/lib

Finally the host architecture must be defined before the build can commence. From a

terminal (assumed to be running the Bash shell) enter the following line:

export EPICS_HOST_ARCH=linux-x86

There is a test application supplied with the device support code. If this is to be used

then the startup script should be altered. cd into the iocBoot/iocpowerPMAC

directory from the top level.

cd iocBoot/iocpowerPMAC

Edit the st.cmd file and update the line that configures the asyn Power PMAC port

with the IP address of the Power PMAC unit on your network. For example

drvAsynPowerPMACPortConfigure("SSH1","10.2.2.76","root",

"deltatau","0","0","0")

Now cd back to the top level and type ‘make’ to build the device support code and the

test application. The build should complete with no errors.

6 Running the Test Application

Once the system has successfully compiled the test application should be executed to

ensure a connection to the Power PMAC is completed.

6.1 Running the EPICS Database

To run the IOC cd into the iocBoot/iocpowerPMAC directory from the top level

directory and execute the st.cmd script.

cd iocBoot/iocpowerPMAC

./st.cmd
