Hi,
clang++ fails with iostream.
Does it go well in your environment?
# I noticed that clang is orphaned. clang requires a maintainer?
$ cat sample.cc
#include <iostream>
int main()
{
std::cout << "Hello World.\n";
return 0;
}
$ g++ sample.cc
$ ./a
Hello World.
$ clang++ sample.cc

That's not a problem with <iostream>, but with <sys/cpuset.h>. It did not
anticipate being compiled with clang. I will submit a patch.
Thanks for the report,
