Can't find file s7plc.dbd

[jwlodek]

Hello all,

this is my first time building s7plc as part of an automated pipeline we are working on for all the epics modules at NSLS2. I am building on RHEL 8, and when I clone the module into my support directory, edit the path in configure/RELEASE and run make, I get the following output:

[jwlodek@rhel8vm s7plc]$ make

Likely I am just missing something since it is my first time. Base version is 7.0.5. Any help would be appreciated, Thanks!

I have not tried this with EPICS 7 yet. Maybe I need to change something in the Makefile.

I was able to build the IOC application by editing the Makefile to the following:

TOP=.
# R3.14+
include $(TOP)/configure/CONFIG

# Want local functions non-static? Define DEBUG
#CFLAGS += -DDEBUG

# Suppress warning in EPICS 7
USR_CPPFLAGS += -DUSE_TYPED_RSET

# library

LIBRARY = s7plc
LIB_SRCS += drvS7plc.c
LIB_SRCS += devS7plc.c
HTMLS += s7plc.html
INSTALL_DBDS += $(INSTALL_DBD)/s7plcBase.dbd
INSTALL_DBDS += $(INSTALL_DBD)/s7plcCalcout.dbd
INSTALL_DBDS += $(INSTALL_DBD)/s7plcReg.dbd
# Uncomment this if you want a dynamically loadable module
#LIB_SRCS += s7plc_registerRecordDeviceDriver.cpp

# stand alone application program
PROD_DEFAULT = s7plcApp
PROD_vxWorks = -nil-
s7plcApp_SRCS += s7plcApp_registerRecordDeviceDriver.cpp
s7plcApp_SRCS += appMain.cc
s7plcApp_LIBS += s7plc
s7plcApp_LIBS += $(EPICS_BASE_IOC_LIBS)
s7plcApp_DBD += base.dbd
s7plcApp_DBD += s7plcBase.dbd
s7plcApp_DBD += s7plcCalcout.dbd
s7plcApp_DBD += s7plcReg.dbd
DBD += s7plcApp.dbd

include $(TOP)/configure/RULES

Though I am not sure if that would break compatibility with previous versions of EPICS base

I've put some time into re-organizing the module a bit to mimic some of the other epics modules I've been working with, the re-organized format builds OK on EPICS 7 as well. It is available on my fork

Hello, everyone,

this is the first time i am building the s7plc with epics 7.0.6.1 and centos 8. Unfortunately, I get the following error message from the compiler. I downloaded the S7plc driver from jwlodek /s7plc. Since I very rarely work with epics, I always have a few difficulties at the beginning. I would be very grateful for hints on troubleshooting.

The swait record is not part of s7plc. You probably added parts of the swait record support but not everything needed. Try to build the s7plc project without swait.

Thanks Dirk, I think I got it working now
