Hi! I have a problem with singleton_pool when I use it into a struct. I think that this problem is my bad knowledge of C++ and not a problem of boost pool. #include <iostream> #include <boost/pool/pool_alloc.hpp> using namespace std; struct data { int a,b; char name[50]; }; struct MyOrderTag {}; typedef boost::singleton_pool<MyOrderTag,sizeof(data)> poolMemory; struct myStruct { struct MyOrderTag {}; typedef boost::singleton_pool<MyOrderTag,sizeof(data)> poolMemory; }; int main() { data *d = (data*)poolMemory::malloc(); //This is ok myStruct ms; // data *d1 = (data*)ms.poolMemory::malloc(); //Error! d->a = 2; poolMemory::release_memory(); return 0; } I obtain a compiler error on row: data *d1 = (data*)ms.poolMemory::malloc(); The poolMemory in struct is only a typedef and not a struct field. How can I use a singleton_pool into a struct? -- View this message in context: http://boost.2283326.n4.nabble.com/Pool-Use-singleton-pool-in-struct-tp46367...
