g++ and ld

[sunil_7]

Is it possible, that we compile the code with
$g++ -c
and then link the objects with ld.

As i am getting the following errors when link with g++ -shared


g++: /opt/gcc/lib/libstdc++.a: linker input file unused because linking not
done
/home/manju/FiltersDepot/sunilfdk/samples/filter/CandCplus/aCC.bat[5]:
echodone compilation: not found.
/usr/ccs/bin/ld: DP relative code in file /var/tmp/ccWehcie.o - shared
library must be position

The latest error for the above problem i am getting is, although i am using -fPIC while compiling

/usr/ccs/bin/ld: DP relative code in file /var/tmp/ccc0Ehoc.o - shared library must be position
independent. Use +z or +Z to recompile.
collect2: ld returned 1 exit status

Sunil,

did you really try like this?.

$g++ -c -fPIC abc.c

Now you can combine the object files into the shared library

$g++ -shared -fPIC -o abc.so abc.o xyz.o

The -fPIC option to gcc (and g++) generate position independent code similar to the way the +z option does in HP's compiler.
