Library versioning interface - urgent
 
Hi,

I have a library say old.so which does not have version
library interface applied.

After a new requirement, I have modified the old.so
to have (ABI) library versioning enabled using mapfiles.
Call the modified one as modified.so

Now the scenario is as follows:

We have applications existing using old.so (by linking to
this library). After the change from old to modified
if the same application wants to use modified.so for linking
and use old.so for runntime.. it seems like there
is backward comaptability problem..

While linking a shared object (A) with another shared object (B) that has version interface enabled , how to supress
recording of version info (like SUNW_1.1) so that, we can
get backward compatibility ??

In solaris it seems like there is an option -z noversion
to suppress version info. Is there any similar one on
LINUX ?

thank you so much , in advance,
-r
