Most of the std algos have iterators as arguments. Visibility seems not to propagate there.. below is my extensive test compile as c++ -O0 -shared -fPIC -fvisibility=hidden -o bha.so testICF.cpp nm bha.so | c++filt and look at the mixture of " t " and " T " for instance 000000000000ad7f t void std::__adjust_heap<__gnu_cxx::__normal_iterator<C**, std::vector<C*, std::allocator<C*> > >, long, C*>(__gnu_cxx::__normal_iterator<C**, std::vector<C*, std::allocator<C*> > >, long, long, C*) 000000000000afea T void std::__iter_swap<true>::iter_swap<__gnu_cxx::__normal_iterator<C**, std::vector<C*, std::allocator<C*> > >, __gnu_cxx::__normal_iterator<C**, std::vector<C*, std::allocator<C*> etc cat testICF.cpp #include<vector> #include<algorithm> #include<cmath> struct A { A(float q=0): v(q){} float v; bool operator<(A const & a) const { return v<a.v;} }; struct B { B(float q=0): v(q){} bool operator<(B const & a) const { return v<a.v;} float v; }; struct C { C(double q=0): v(q){} bool operator<(C const & a) const { return v<a.v;} double v; }; float cosq(A const & a) { return cos(a.v); } float cosq(B const & a) { return cos(a.v); } template<typename T> int game(std::vector<T> const & a, std::vector<T> & b) { typedef typename std::vector<T>::const_iterator Iter; for (Iter i=a.begin(); i!=a.end(); ++i) { if ( (*i).v>0.) b.push_back((*i).v+1); } std::sort(b.begin(),b.end()); return b.size(); } template<typename T> int gamep(std::vector<T*> const & a, std::vector<T*> & b) { typedef typename std::vector<T*>::const_iterator Iter; for (Iter i=a.begin(); i!=a.end(); ++i) { if ( (*i)->v>0.) b.push_back((*i)); } std::sort(b.begin(),b.end()); return b.size(); } namespace data /* __attribute__((visibility("default"))) */ { std::vector<A> a; std::vector<B> b; std::vector<C> c; std::vector<A*> ap; std::vector<B*> bp; std::vector<C*> cp; } #include<iostream> int __attribute__((visibility("default"))) go() { using namespace data; int ret=0; try { ret+=game(a,a); ret+=game(b,b); ret+=game(c,c); ret+=gamep(ap,ap); ret+=gamep(bp,bp); ret+=gamep(cp,cp); } catch (std::exception & ce) { std::cout << ce.what() << std::endl; } return ret; }
