Mark

Thanks for the help again. Have things working now, and the sCalcout does

what I want. Excellent! Needed to run the make at the top level. I'm afraid

I'm still getting the hang of things.

Steve,

If you are getting this error:

No rule to make target ..... libcalc.a ....

then make is not looking in the right place for libcalc.a. If you added the

line to configure/RELEASE

CALC=/home/steve/epics/calc/2-6-7

then perhaps you did not run make in the configure/ or top level directory

of your application? If that does not solve the problem then please send

the output of your build so we can see what is and is not being searched.

Is the second dbd step necessary for the app make?

It is necessary to have calcSupport.dbd in your xxxInclude.dbd file in order

for your application to have access to the sCalcout record and other things

defined in calcSupport.dbd

Mark

Thanks Mark

Forgot to say I had already added the following to my apps configure/RELEASE
file, based on looking at what else was already in there.

CALC=/home/steve/epics/calc/2-6-7

This directory is where I had extracted the calc module and done a make. So
it contains a lib/linux-x86 directory containing libcalc.a and libcalc.so.

Is the second dbd step necessary for the app make?

Just add the path to the calc module to your applications configure/RELEASE
file.

You don't need to do anything with LD_LIBRARY_PATH.

You do also need to add calcSupport.dbd to you application's xxxInclude.dbd
file.

Subject: Using SynApps Calc Module

I am trying to use the SynApps calc module in a Linux IOC. I would like to
use sCalcout records in my application. The calc documentation says to
include calcSupport.dbd and link to libcalc. Trying to do the 2nd part first
I tried adding lines like app_LIBS += calc in my Makefiles but I get errors
like

No rule to make target ..... libcalc.a ....

I have already downloaded the calc module and done the make. I hoped adding
the calc lib directory to my LD_LIBRARY_PATH  would then make the
application link work.

Could anyone offer me some advice on how to link libcalc with my application
please.

Thanks

Steve
