Hello,
I am trying to migrate my project to the Goa build system. However, when I try running Genode throws 'Genode::Xml_node::Nonexistent_sub_node'. Below I have provided a simplified file containing the isolated code from where the error is thrown along with the full runtime file. Line 13 is the where the error is thrown from.
I cannot figure out why this is not working, since it works just fine with the traditional build system (i.e. with make).
Any help will be greatly appreciated!
Best, Rumen
Hi Rumen,
I gave this a test run and noticed that your runtime file is very odd. First of all, there are multiple start nodes but it also mentions 'binary="squid"'. I guess the runtime is rather indented to use init, hence you'll need to add 'binary="init"' instead. In this case, the XML provided as <config> must be understood by the init component. Your config is missing the '<parent-provides>' and you likely also want to add a '<default-route>' and '<default caps="..."/>'.
Please have a look at 'goa help runtime' and Section 6.2 "The init component" of the Genode Foundations book for more details.
Note that, with Goa, you do not need to add your own timer component as Goa is taking care of this.
Cheers Johannes

Thanks that solved it!
I was also wandering how to add lx_block to my runtime. I cannot seem to find the corresponding depot url to put in my archives file. The closest I found was _/src/lx_block in repos/os/recipes/pkg/test-lx_block/archives, but from what I can tell that is relative to test-lx_block.
Best, Rumen

The depot recipe is in repos/os/recipes/src/lx_block. Since this, however, is not part of Sculpt OS nor the Goa release, it is not published on the genodelabs depot. You therefore have to build it yourself using tool/depot/create (see Section 5.5 of Genode Foundations).
