static and shared library options for aCC

Ram Regar — Wed, 11 Nov 2009 00:54:50 GMT

Hi,
I have

module1 should be built as static library.
module2 should be a shared library and it should like module1 statically.

module3 is an executable which dynamically links to module2 library.

I am looking for aCC command options to achieve this goal.

It should work on 64 and 32 bit OS.

Thanks,
Ram

>module1 should be built as static library.

(The correct HP-UX terminology is archive lib.)
What OS and architecture are you using?

>I am looking for aCC command options to achieve this goal.

aCC -c foo1.c foo2.c
ar -rv libmod1.a foo1.o foo2.o

aCC -c +z foo3.c foo4.c
aCC -b o libmod2.so foo3.o foo4.o -L . -lmod1

aCC -c foo5.c foo6.c
aCC -o module3 foo5.o foo6.o -L . -lmod2

Thank you for ur response.

I have this box.
-bash-3.2$ uname -a
HP-UX ramregar-hp11i B.11.23 U ia64 1869050062 unlimited-user license
-bash-3.2$

I want to build 32-bit and 64-bit builds on the same box.
Thanks,

The default is 32 bit or you can use +DD32.
And +DD64 for 64 bit.

Thank you so much for your support so far. Please do continue until I finish this.

Module1 a static library.
aCC -O -g0 -O2 +Oopenmp +z +DD64 -b -Wl,-ashared -D_HPUX -D__LP64__ -DPIC -I/build/jdk/include -lunalign -o/build/rel/lib/static/libmodule1.a *.cpp *.c

Module2 a dynamic library which statically links the Module1
aCC -O -g0 -O2 +Oopenmp +z +DD64 -b -n -v -D_HPUX -D__LP64__ -I/build/jdk/include -Wl,-L/build/rel/lib/static/ -lmodule1 -o/build/rel/lib/libmodule.so *.cpp *.c

Module3 a dynamic library which statically links the module1
aCC -O -g -O2 +Oopenmp +z +DD64 -b -v -ashared -D_HPUX -D__LP64__ -L/build/rel/lib/static/ -lmodule1 -o/build/rel/lib/libmodule3.so *.cpp

Module4 an executable which dynamically links module2. Module2 loads Module3 at runtime.
aCC +DD64 +Oopenmp -I/build/clients/include -L/build/rel/lib/ -lmodule2 -lrt -lunalign -o/build/bin/module4 *.cpp

aCC version:
aCC: HP C/aC++ B3910B A.06.23 [May 18, 2009]

Problem:
When I run module4
/usr/lib/hpux64/dld.so: Unsatisfied data symbol '_ZTV14MyListener' in load module '../lib/libmodule2.so'.
Killed

I looked in library with nm command. Here is the output.

build@hp16 /build/rel/lib $ nm -D libmodule2.so | grep MyListener

I would appreciate your help. Please do review compiler options and suggest me the changes.

>module1 a static library.

Again, please use the correct terminology. There are only archive and shared libs.
In this case, this is a shared lib since you used -b and not ar(1).

>aCC -O -g0 -O2 +Oopenmp +z +DD64 -b -Wl,-ashared -D__LP64__ -lunalign -o /build/rel/lib/static/libmodule1.a *.cpp *.c

There is no need for both -O and +O2. There is no need to define -D__LP64__ or -Wl,-ashared, they are set by the driver or the default. Also, why bother with +Oopenmp?
Also, you should NOT use -b with libmodule1.a. Rename it to libmodule1.so.

>module2 a dynamic library which statically links the module1
>aCC -O -g0 -O2 +Oopenmp +z +DD64 -b -n -v -Wl,-L/build/rel/lib/static/ -lmodule1 -o /build/rel/lib/libmodule.so *.cpp *.c

The output should be libmodule2.so
Remove useless -n. Also remove "-Wl," before -L.

>module4 an executable which dynamically links module2. module2 loads module3 at runtime.
>aCC +DD64 +Oopenmp -lmodule2 -lrt -lunalign -o/build/bin/module4 *.cpp

And also has module1 as a dependent shlib.

dld.so: Unsatisfied data symbol _ZTV14MyListener load module ../lib/libmodule2.so
>I looked in library with nm command.

Where should it be defined? Where have you defined the class MyListener and the first non-inline virtual function?
