Hi Renato,


You need to put each of the EPICS 4.6.0 modules in your application's configure/RELEASE file.  For example:


EV4_BASE=/corvette/usr/local/epics/epicsV4/EPICS-CPP-4.6.0
PVCOMMON=$(EV4_BASE)/pvCommonCPP

PVACCESS=$(EV4_BASE)/pvAccessCPP
PVDATA=$(EV4_BASE)/pvDataCPP
PVDATABASE=$(EV4_BASE)/pvDatabaseCPP
NORMATIVETYPES=$(EV4_BASE)/normativeTypesCPP
EPICS_BASE=/corvette/usr/local/epics/base-3.15.5


The EPICS build system will search all modules listed in configure/RELEASE for include files, dbd files, library files, etc.

Mark

Subject: Telling gcc the location of EPICS

Hi,

This is probably a newbie question. I have built EPICS base and EPICS 4.6.0 modules following the instructions in the README files. But I notice that gcc doesn't know where the headers are. The linker doesn't know either. So when I compile a program using pv/pvAccess I get an error (of course). I found that I can add the paths to  $CPLUS_INCLUDE_PATH and $LD_LIBRARY_PATH manually for fixing the errors.

Is there a more practical way to do it?

The path to my EPICS base is: /opt/epics/base
The path to EPICS v4 modules is: /opt/epics/EPICS-CPP-4.6.0

But if I want to compile a program I will have to add many subdirectories of the previously mentioned directories manually.

Best regards,
