Hi. We'll be compiling a schema.

Pre-reqs

Only the basics: https://gist.github.com/rektide/6588445#pre-reqs

Compiling schema.capnp

This is the bootstrap schema! The types it encodes are used to define all other types that will ever be made.

In our case, we just want to compile something and see that thing.

Create a working space

mkdir /tmp/dive-i
cd /tmp/dive-i

Add sources

ln -sf $CAPNP_DIR/c++/src/capnp/{schema,c++}.capnp .

Compile

capnp compile -oc++ schema.capnp

Look! Results

ls -l

  lrwxrwxrwx 1 rektide rektide     55 Sep 16 20:31 c++.capnp -> /home/rektide/archive/capnproto/c++/src/capnp/c++.capnp
