# Hello, BPF CO-RE!

## Trouble Shooting

### `clang` cannot compile BPF source files

If you cannot build a BPF source file with the following messages:

```

build/vmlinux.h:4629:20: error: expected member name or ';' after declaration specifiers

        struct cgroup_bpf bpf;

                          ^

:284:13: note: expanded from here

#define bpf 1

```

Then, your `clang` could be too old. I've confirmed clang-8 cannot build BPF source files but clang-10 can do.
