Re: [porting-dev] Compiling Error in PPC with gcc-3.2
Hi,
I think there is some misunderstanding.
Our OOo tree officially has the following in it in memmgr.cxx
std::new_handler
SAL_CALL std::set_new_handler (std::new_handler pfnHandler) throw ()
{
std::new_handler f = g_pfnHandler;
g_pfnHandler = pfnHandler;
return f;
}
But for some reason your version is showing the "throw ()"" commented out.
I posted a gcc 3.1.1 patch that did exactly this but it should have never
made it into any tree since all it did was workaround a gcc 3.1.1 pre
compiler problem (gcc headers never had the throw() which was actually
spec (set_new_handler may not throw any exceptions according to the rules)
but gcc was never picky about the throw specifier before 3.1.1 pre.
So please back out the patch in memmgr.cxx (probably that came from my gcc
3.1.1 patch) that comments out the throw() on the set_new_handler code (to
make it look like it did previously) and you should be fine.
Hope this explains things in more detail.
