compiling with automake

[SR D]

I would like to make use of capnproto in an autotools project and wondering if anyone has any references or examples as to how to do basic compiling with a Makefile.am. Especially w.r.t. the cmake equivalent of capnp_generate_cpp().

Any help appreciated.

It should work as a subpackage. See:

Hi Kenton,

I don't have an issue with setting up and building libraries and linking my own programs to external libs like capnproto using Autotools. My problem is that, I have a test.capnp file and I don't know how to call/run the capnp tool via a Makefile.am to produce the *.capnp.h and *.capnp.c++ files.

Or did I miss your point in understanding that this would happen by nesting packages?

Once the capnp subproject build is done, you should be able to invoke the `capnp` compiler straight from the subproject location. I think you'd have to write a raw make rule that invokes the compiler. You can see how Cap'n Proto's own build does this here:
