Watcom C++ does not allow nested vectors?

[Lynn McGuire]

I had to put a #ifndef around some common code between my Visual Studio app and my Watcom C++ app. Does Watcom C++ not support
nested vectors?

#ifndef __WATCOMC__
// Watcom C++ has a big problem with nested vectors
std::vector <std::vector <std::string>> data;
#endif


Thanks,
Lynn

You need to write that with a space inside the ">>". Otherwise ">>" looks
like a shift operator.

std::vector < std::vector<std::string> > data;

This is standard C++ 98. The new standard requires compilers to work it
out without the space. I actually think Open Watcom might implement this
if you turn on the c++0x support (such as it is).
