Experimental Physics and
Industrial Control System

I’ve been trying to track down the reason for multiple inclusions of the xxxMain.o when I build a library.

The output of the build looks like this:

 

/usr/bin/ar -rc    libaaitest.a      devAaiIQM.o aaitest_registerRecordDeviceDriver.o aaitestMain.o aaitestMain.o

 

Where aaitestMain.o appears twice, and causes a “multiple definition of ‘main’ “ problem.

 

Here is my App/src/Makefile:

TOP=../..

 

include $(TOP)/configure/CONFIG

#----------------------------------------

#  ADD MACRO DEFINITIONS AFTER THIS LINE

#=============================

# Build an IOC support library

 

LIBRARY_IOC += aaitest

 

DBD += aaiIQM.dbd

aaitest_SRCS += devAaiIQM.cpp

aaitest_LIBS += $(EPICS_BASE_IOC_LIBS)

 

# additional compile flags for adinstbpm code called in device support

USR_CXXFLAGS += -g

USR_CXXFLAGS += -DNETCOMMS_TRANSPORT=UDP

USR_CXXFLAGS += -fPIC

USR_INCLUDES += -I/home/rsantucc/adinstbpm

USR_INCLUDES += -I/usr/local/products/erlang-apps/cdev-1.3/include

USR_INCLUDES += -I/usr/local/products/erlang-apps/acnet-2.2/include

USR_INCLUDES += -I/usr/local/products/include/shared/ddcp

USR_INCLUDES += -I/usr/local/products/include

USR_INCLUDES += -I/usr/local/products/trace/include/TRACE

USR_LDFLAGS += -lbpmclientlib

USR_LDFLAGS += -lbbpm250x12

USR_LDFLAGS += -lbtime

USR_LDFLAGS += -liotatime

USR_LDFLAGS += -lddcp

USR_LDFLAGS += -lconfig++

USR_LDFLAGS += -lnl-genl-3

USR_LDFLAGS += -lnl-3

USR_LDFLAGS += -lrt

 

#=============================

# Build the IOC application

 

PROD_IOC = aaitest

 

# aaitest.dbd will be created and installed

DBD += aaitest.dbd

 

# aaitest.dbd will be made up from these files:

aaitest_DBD += base.dbd

aaitest_DBD += aaiIQM.dbd

 

# Include dbd files from all support applications:

#aaitest_DBD += xxx.dbd

 

# Add all the support libraries needed by this IOC

#aaitest_LIBS +=

 

# aaitest_registerRecordDeviceDriver.cpp derives from aaitest.dbd

aaitest_SRCS += aaitest_registerRecordDeviceDriver.cpp

 

# Build the main IOC entry point on workstation OSs.

aaitest_SRCS_DEFAULT += aaitestMain.cpp

aaitest_SRCS_vxWorks += -nil-

 

# Add support from base/src/vxWorks if needed

#aaitest_OBJS_vxWorks += $(EPICS_BASE_BIN)/vxComLibrary

 

 

# Finally link to the EPICS Base libraries

aaitest_LIBS += $(EPICS_BASE_IOC_LIBS)

 

#===========================

 

include $(TOP)/configure/RULES

#----------------------------------------

#  ADD RULES AFTER THIS LINE

 

 

 

Any ideas would be appreciated –

Thanks,

Dave
