> I am trying to use Boost built using stdcxx on Solaris. I was able to build the date_time
> library but when I try to compile a test program I end up with errors related to incomplete
> types. I have narrowed the issue to the following code
>
> #include <map>
> #include <string>
> using namespace std;
> template <class T>
> struct C {
> typedef multimap<T,C> maps;
> typedef typename maps::value_type value_type;
> };
>
> int main () {
> C<std::string> c;
> }
> When I compile using the default Sun CC libraries or rwtools7_std or stlport4, the code
> compiles fine. But when I compile using stdcxx, I end up with the following errors.
