[dtrace-discuss] Getting error ld: fatal: symbol `__SUNW_dof' is multiply-defined:

[[EMAIL PROTECTED]]

I have 2 .cpp  files in two different directories in which I need to put DTrace 
probes. They are compiled into two .a libraries one after another. In the end 
they are combined to a single .so file. This sequence I can not change. I get 
an error "ld: fatal: symbol `__SUNW_dof' is multiply-defined:". What is the 
solution for this?

Here is my simulation of real world problem in sample files.

$gmake
CC -mt -xtarget=ultra -g -xs -c -o a.o a.cpp
dtrace -G -32 -s 1.d a.o -o 1.o
CC -xar -o liba.a a.o 1.o
CC -mt -xtarget=ultra -g -xs -c -o b.o b.cpp
dtrace -G -32 -s 2.d b.o -o 2.o
CC -xar -o libb.a b.o 2.o
CC  -G -o libc.so a.o b.o 1.o 2.o -mt -norunpath
ld: fatal: symbol `__SUNW_dof' is multiply-defined:
        (file 1.o type=OBJT; file 2.o type=OBJT);
ld: fatal: File processing errors. No output written to libc.so
