## 2 Build autofdo tools

Note, "-DBUILD_SHARED=On" is required for CentOS 9, this will build the tools linked with shared libraries. For Ubuntu 20.04 and Ubuntu 22.04, "-DBUILD_SHARED" is optional, when it is not given, this will build the tools linked statically.

```

$ cd autofdo
$ mkdir build
$ cd build
