do you have libstdc++ installed?

[retsyo]

I have I can compile

#include <string>
#include <iostream>

int main(){
    std::string s;
    s = "Hello World!";
    std::cout << s << '\n';
}

by using g++ a.cc, then

$ ./a.exe
Hello World!

if I add {.passL: "-lstdc++" .} on the header of uibuilder.nim, then

$ nim c -r uibuilder.nim
