lwip examples

[Amadeo Cuadrado]

Thanks Stefan for your answer. Yes, I am building lwip and libc statically.

I am using qemu to run the .iso, basically:

qemu -cdrom  'myiso.iso' -net nic,model=pcnet

I have also used VBox, with same luck. This is the Nic driver I am using:

<start name="gpxe_nic_drv">
	<resource name="RAM" quantum="4M"/>
	<provides><service name="Nic"/></provides>
</start>

This is the output from the serial port:

int main(): --- create local services ---
int main(): --- start init ---
int main(): transferred 431 MB to init
int main(): --- init created, waiting for exit condition ---
[init -> test-lwip_loop] void init_loopback(): init_loopback()
[init -> test-lwip_loop] Libc::Lwip_plugin::Lwip_plugin(): using the lwIP libc plugin
[init -> test-lwip_loop] void init_libc_lwip(): init_libc_lwip()
[init -> test-timer] --- timer test ---
[init -> test-lwip_loop] int server(): Create new socket ...
[init -> test-lwip_loop] virtual void Client::entry(): Create new socket ...

And then it just stops there.

What do you mean exactly about the signaling framework? Are these examples supposed to not work yet?

Thanks,
Amadeo

Hello Amadeo,

thank you for pointing us out to the build-problem in the linux_drivers
repository. We immediately fixed that problem. You can checkout the fix
from our subversion repository.

With respect to your problems related to lwip. I assume that you
compiled lwip and libc as static libraries, as ldso and shared libraries
aren't supported for Genode/Fiasco.OC yet?

Without knowing much details I would guess it's a configuration issue.
Could you please provide some information with respect to your
test-environment, like what hardware or VM you use, especially which NIC
you've enabled? Moreover, the init-configuration and the complete serial
output would be helpful.

But even when we fix your (probably configuration-)issues it's unlikely
that the NIC service will work out of the box now, because it's based on
the signalling framework, which isn't supported yet. But we work on
that, and it will be supported at the latest by the upcoming release.
Nevertheless, the mentioned problems have nothing to do with a
non-functional signalling framework.

Regards
Stefan
