Compiling HP-UX 11.23

Carlo Henrico_1 — Wed, 22 Mar 2006 04:31:45 GMT

I can't link archive or shared libraries that include STL (standard template library) code.
If I compile and link the code without making use of an archive library step, it works.
As soon as I include the STL code within the archive or shared library, the link step fails.

Here is my .mk file:

#--------------------------------------------------------------
# HP-UX C++ compiler
#--------------------------------------------------------------
COMPILE=/opt/aCC/bin/aCC
CCFLAGS= -AA -c -v +p +DA2.0 +DS2.0 \
-D_HPUX_SOURCE \
-D_POSIX_C_SOURCE=199506L \
-DRWSTD_MULTI_THREAD \
-DRW_MULTI_THREAD \
-D_REENTRANT \
-D_THREAD_SAFE

#--------------------------------------------------------------
# HP-UX C++ linker
#--------------------------------------------------------------
LINK=ld
LDFLAGS= \
/opt/langtools/lib/crt0.o \
/opt/aCC/lib/cpprt0.o \
-L /opt/aCC/lib \
-v \
+vallcompatwarnings \
+pd 16M \
-lstd_v2 \
-lCsup_v2 \
-lm \
-L$(ORACLE_HOME)/lib32 \
-lclntsh

#--------------------------------------------------------------
# excutable
#--------------------------------------------------------------
exe: main.o failing.a
$(LINK) $(LDFLAGS) main.o -o tester.exe

main.o : main.cpp
$(COMPILE) $(CCFLAGS) main.cpp

failing.a : failing.cpp
$(COMPILE) $(CCFLAGS) failing.cpp
ar r failing.a failing.o
#--------------------------------------------------------------

Any ideas please?

Thanks

Carlo

You didn't mention how the link step failed.

Generally you must NOT use ld to link aC++ applications. Use aCC instead.

You need to change your LDFLAGS to remove the default libs and then you need to add -AA. And change ld specific options to the -Wl form: -Wl,+pd,16M.

This is the error I get:

ld: Unsatisfied symbols:
fxFailingToLink__Fv (first referenced in main.o) (code)
*** Error exit code 1

Where have you defined fxFailingToLink(void), in failing.cpp?

I don't see failing.a added to your link line, after main.o

Hi Dennis

I think the problem is with the creation of the archive file
"ar r failing.a failing.o"

If it is compiled with just the objects (failing.o) all is fine, but as soon as an archive is created, it is as if the archive file (failing.a) is not picked up?

Dennis

Your comment got me on the right track...hence the points, thanks.

PS: The problem was the link command:
$(LINK) $(LDFLAGS) main.o -o tester.exe
did not include the .a as follows:
$(LINK) $(LDFLAGS) main.o failing.a -o tester.exe

Cheers
