20 Tutorial part 1: "Hello world"
21 ==============================
23 Before we look at the details of the API, let's look at building and
24 running programs that use the library.
26 Here's a toy "hello world" program that uses the library's C++ API to
27 synthesize a call to `printf` and uses it to write a message to stdout.
29 Don't worry about the content of the program for now; we'll cover
30 the details in later parts of this tutorial.
32 .. literalinclude:: ../../examples/tut01-hello-world.cc
35 Copy the above to `tut01-hello-world.cc`.
37 Assuming you have the jit library installed, build the test program
40 .. code-block:: console
43 tut01-hello-world.cc \
44 -o tut01-hello-world \
47 You should then be able to run the built program:
49 .. code-block:: console
