Hi,
I just installed GhostBSD 24.10.1 and one of the first things I wanted to try was a C/C++ compiler. So I created a simple hello world app:
#include <iostream>
int main()
{
std::cout << "Hello on FreeBSD!" << std::endl;
return 0;
}
Then I tried to compile it: c++ -v hello.cpp and it gave me this error:
FreeBSD clang version 18.1.6 (https://github.com/llvm/llvm-project.git llvmorg-18.1.6-0-g1118c2e05e67)

I thought FreeBSD came with a built-in C/C++ compiler that works, but for some reason only the clang binary seems to work on my machine, not the includes. I also tried to find the iostream header with find / -name iostream but didn't find anything. What am I doing wrong and how can I fix this?
