Duplicate symbol "sqlca" in files <file1.o> <file2.o>

[soumya das]

I am getting the same problem as Peter's while running makefile. The error is Duplicate symbol "sqlca" in files .

My aCC version is
aCC: HP ANSI C++ B3910B A.03.33

Still I'm having the same error. can anyone pls. help me out?

Soumya,
I was told version 3.33 would have the fix.

Have you tried ranganath ramachandra idea with the +allowdups ?
Available with the latest linker (PHSS_28434/PHSS_28436 : B.11.36).

Hi Peter,

Thanks for your reply.

I downloaded the patch. But how to use that "+allowdups" ? I have a makefile. Where this "+allowdups" is to be used? Can you help me in this regard.

The link did not copy correctly, should be:
http://docs.hp.com/en/B2355-60105/ld_ia.1.html

Hi,
Thanks for the documentation.
I used "+allowdups" in LD_FLAGS option along with many other options like -Z and -b etc.

But the following error is still comming :

aCC: warning 901: unknown option: `+allowdups'

and the duplicate symbol "sqlca"

Soumya,
try the following:
remove the allowdup flag
include a -h sqlca in your link stage
This should hide the symbol at a local level.

I found the original problem and reply:

"Hi Pete,

I've identified the problem you're seeing. It is a bug in the compiler and
listed as:

JAGad39135 -Ae enum constants, results in duplicate symbols at link
time

The problem is that the compiler is incorrectly making enum constants global
to the program whereas they should be local to the file being compiled. This
is resolved in aCC compiler revisions A.03.33 and later. You currently have
A.03.30. To obtain a later revision you will have to install a new compiler
from application CDs from December 2001 or later. Please see
http://hp.com/go/c++ for details of the revisions available and required
patches for each. The later the revision the better, but anything including
A.03.33 and after will resolve this problem."

Hi,

thanks for ur reply ..

Actually I have a makefile which is as shown in the attatchment. Pls. see the attatched notepad file.


Here in the LD_FLAG I am using those options loke -allowdups and -h sqlca as u said. But errors are coming saying these options are not allowed there.

The option +allowdups is working with ld separately for the object files.

Can u give any suggestions regarding how to modify my makefile so as to remove the duplicate sqlca errors?

Soumya,
an extract from our make script:
ld -h sqlca -h __SIGEV_NONE -h __SIGEV_SIGNAL -h __SIGEV_THREAD -h CLOCK_INVALID -h CLOCK_REALTIME -h CLOCK_V
IRTUAL -h CLOCK_PROFILE -h RTTIMER0 -h RTTIMER1 -h SI_QUEUE -h SI_USER -h SI_TIMER -h SI_ASYNCIO -h SI_MESGQ -h P_PID -h P_PGID -h P
_SID -h P_UID -h P_GID -h P_CID -h P_ALL -r -o 1.o

Hi peter,

following is the make file code .. I used in the LD_PATH those options like +allowdups and -h sqlca. But they are not allowed there.
These options are allowed with ld. I tried the +allowdups which worked with one warning of overriding the sqlca in one object file.


include ../../Include_Paths

CC = /opt/aCC/bin/aCC
CCFLAGS = -g0 +Z -D_HPUX_SOURCE -DRW_MULTI_THREAD -D_REENTRANT -mt
.SUFFIXES :
.SUFFIXES : .cc .h .pc .o

PROC_COMP = $(ORACLE_HOME)/bin/proc
PROC_FLAGS = CODE=CPP CPP_SUFFIX=cc
PROC_INCLUDE = SYS_INCLUDE=/opt/aCC/include/iostream SYS_INCLUDE=/opt/aCC/include

PROC_src=AlertDBConnectionManager.pc

SRCS = $(PROC_SRC:.pc=.cc)
CC_SRCS = $(SRCS) AlertCollectionManager.cc AlertEntry.cc AlertServer.cc ClientSurveillanceObject.cc EventInterfaceServer.cc
OBJS = $(CC_SRCS:.cc=.o)

IFLAGS = -I$(COLLECTIONAPI) -I$(CONFIGURATIONAPI) -I$(EVENTAPI) -I$(SOCKETAPI)

LD_FLAGS = -L$(CONFIGURATIONAPI) -L$(COLLECTIONAPI) -L$(EVENTAPI) -L$(SOCKETAPI) -L$(MQAPI) -lconfigurationmanager -lcollectionmanager -leventmanager -lsocketlib -b

TARGET = AlertServer

$(TARGET) : $(OBJS)
$(CC) $(OBJS) $(CCFLAGS) $(LD_FLAGS) -o $@
chatr +s enable $(TARGET)

.pc.cc:
$(PROC_COMP) $(PROC_FLAGS) $(PROC_INCLUDE) $<

.cc.o: $(CC_SRCS)
$(CC) $(CCFLAGS) $(IFLAGS) -c $< -o $@

clean:
rm -rf $(SRCS) $(OBJS) *.lis

Soumya,
so this mean it is now working?
The -h option was added to the ld stage of the make. See my pevious mail.
Hope this is the solution.
Regards

[soumya das]

Hi peter,

If I add the -h option in the LD_FLAG errors are coming that -h is not recognised there. The same is case for +allowdups.

My prob. is where in my make file can the option -h sqlca or +allowdups be added.

[soumya das]

Hi Peter,

Could you find out any solution??

-- regards,

soumya

[Peter Godron]

Soumya,
please amend:
LD_FLAGS = -L$(CONFIGURATIONAPI) -L$(COLLECTIONAPI) -L$(EVENTAPI) -L$(SOCKETAPI) -L$(MQAPI) -lconfigurationmanager -lcollectionmanager -leventmanager -lsocketlib -b
to
LD_FLAGS = -hsqlca -L$(CONFIGURATIONAPI) -L$(COLLECTIONAPI) -L$(EVENTAPI) -L$(SOCKETAPI) -L$(MQAPI) -lconfigurationmanager -lcollectionmanager -leventmanager -lsocketlib -b
and try it (added -hsqlca [no space])

[soumya das]

Hi Peter,

I amended as u told .. but the error persists and says "unknown options -hsqlca".

This option works with ld option ie. ld -h sqlca is not giving any error.But not with the LDFLAG options.

Actually it's not recognising the sqlca symbol in the makefile.

Can in any ways the ld option be included in the makefile like ld -h -sqlca be included?? Or we have to put the -h -sqlca in a place where make file will understand the sqlca symbol.

[Peter Godron]

Soumya,
we will need a little help from a make expert for this final part. We have written our own scripts for compilation and we separate the process into ProC Pre-compile, C compile and ld steps.

I would suggest you complete this thread with the exisiting solution of adding the -hsqlca and allowdups parameters.

Then open a new thread calling all make experts (include a brief description of the problem and proposed solution).
Many Thanks

[soumya das]

Ok, Peter,
Many thanks. I would do what you suggetsed.

--regards,
soumya

[soumya das]

Hi,

I think the thread should be completed now.
-h sqlca and +allowdups are some options that can be used with ld.
