Shared library linking with external static libraries.

[FloofLeBo]

Thanks !

My application links with the shared object, and it runs with no problems !
My symbols appear in "nm -C -g --defined-only" and only the symbols I want !
Nice !

Thanks you so much ! You guys rock !

And now I'll go to the dead-stripping. How can I be sure that unused code
from the external and internal static libraries is not shipped with the
shared object ?

I tried naively to add the "-Wl,-dead-strip" to the gcc -shared command, but
this gave me the warning:

/usr/bin/ld: warning: cannot find entry symbol ad-strip; defaulting to
0000000000071f00

What would gcc need to only pull needed code for the static libs ?

Kind regards,
Florent.
