chaiscript_compiled_in_stdlib.cpp

#include <chaiscript/chaiscript.hpp>
#include <chaiscript/chaiscript_stdlib.hpp>
 
std::string helloWorld(const std::string &t_name)
{
  return "Hello " + t_name + "!";
}
 
int main()
{
  chaiscript::ChaiScript chai(chaiscript::Std_Lib::library());
  chai.add(chaiscript::fun(&helloWorld), "helloWorld");
 
  chai.eval("puts(helloWorld(\"Bob\"));");
}

Looks like this example need to be updated... The latest version of ChaiScript doesn't work with this usage. I think you'd need to replace ChaiScript with ChaiScript_Basic, in order for the first argument to still be the Std_Lib::library() (e.g. if you want to compile the standard library in a separate file). It seems you've changed the default ChaiScript constructor to create Std_Lib by default, rather than searching for an external library at runtime, as mentioned here.
