Subject: iostream doesn't work (clang++)
Date: Wed, 5 Jul 2023 01:48:08 +0900 [thread overview]
Message-ID: <7e07e251-2ec6-b7a5-62da-8578eb638993@gmail.com> (raw)
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
