I am current developing a shared library (libMainapi.so) which intergrating with the Cobra client service:
Source:
-Mainapi.cpp
-CobraClient_c.hh
-CobraClient_c.cc

Mainapi.cpp will include CobraClient_c.hh

I can successfully compile Mainapi.cpp and CobraClient_c.cc separately and built the Mainapi.o and CobraClient_c.o object.  However I don't know how to link up them together to build the libMainapi.so library.  Can anyone provide the exact command with parameter for the object linking? Thanks.

P.S. I am using VisiBroker's idl2cpp to generate the CobraClient_c.hh and CobraClient_c.cc file.

ld -G -z text -o libMainapi.so Mainapi.o CobraClient_c.o

beware that you need to supply the "-K pic" option on the cc command line, so that both object files you created contain relocatable code.

I got the following error following your ld command
ld: fatal: relocations remain against allocatable but non-writable sections

I cannot specify the K parameter within the ld command

 

by: kalamariusPosted on 2009-01-15 at 23:20:17ID: 23390772

"-K pic" is needed in the "cc" command, to create relocatable code.
