When compiling the following code, I get these errors.
(ucontext is deprecated, but these functions should still redefined)
clang++ -o main uclib.cpp -std=c++0x -U__STRICT_ANSI__ -stdlib=libc++
----- uclib.cpp--------
#define _XOPEN_SOURCE 520
#include <ucontext.h>
#include <iostream>
int main() {
std::cout << "Hello World!"<<std::endl;
}
