Hi, The -fvisibility feature in GCC 4.0 is a really useful way of hiding all non-public symbols in a dynamic shared object.
While I'm aware of a patch which backports this feature to GCC 3.4 (over at nedprod.com), I was wondering whether there is a similar patch available for GCC 3.3. I'm aware that GCC 3.3 (and some vintages of 3.2) support the __attribute__ means of setting a symbol's visibility, but I want to be able to change the default visibility for all symbols. The problem is that we're stuck for now with the GCC 3.3 compiler as we need v5 ABI compatibility for Orbix 6.2 and cannot move to 3.4 until Iona catch up. Does anyone know if such a patch exists, or even if it is feasible in the 3.3 framework? Thanks, Gary
