HI Jörn,

I am successfully doing what you are trying to do using RELEASE*.local files that are identical to the EXAMPLE_RELEASE*.local files in the master branch of  areaDetector/configure.

I suspect you did not define the path to the V4 libraries in RELEASE_PATHS.local.  This is the symbol EV4_BASE. My version of that file contains these lines:

# If CONFIG_SITE.local defines WITH_EPICS_V4=YES then define the path here
EV4_BASE     = /corvette/usr/local/epics-devel/epicsV4/EPICS-CPP-4.6.0


RELEASE_LIBS.local contains these lines:

# V4 modules.
PVCOMMON=$(EV4_BASE)/pvCommonCPP
PVACCESS=$(EV4_BASE)/pvAccessCPP
PVDATA=$(EV4_BASE)/pvDataCPP
PVDATABASE=$(EV4_BASE)/pvDatabaseCPP
NORMATIVETYPES=$(EV4_BASE)/normativeTypesCPP

Let me know if you still have problems.

Mark

Subject: EPICS areadetecto and EPICSV4

Hi all,

I have a probably stupid question concerning the use of EPICS V4 and the
areadetector code in an IOC.

I'm trying to build an IOC with which I want to readout a GiGE based camera.
To do performance comparisons I also want to include the EPICS V4 code. But If
I enable WITH_EPICS_V4 in the Makefile, I fail to find the  „../../../lib/linux-
x86_64/libpvDatabase.a“ The makefile is searching in the wrong directories. I
included

include $(AREADETECTOR)/ADCore/ADApp/commonDriverMakefile

in my IOC makefile. And therein the EPICS V4 libraries are added to PROD_LIBS.
What variable do I need to set so that make will find those libraries? If I
change PROD_LIBS to PROD_SYS_LIBS, everything compiles fine.

With kind regards,

Jörn Dreyer
