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

Hello,
I have not been able to run any of the lwip examples (I am using 32 bits): loopback hangs in socket() call, and http_srv hangs in the lwip_nic_init() call. I am using the Nic driver from dde_gpxe, since I got compilation errors when building the linux_drivers:
.../genode/linux_drivers/src/linux26/arch/i386/lib/bitops.c: In function 'find_next_zero_bit':
.../genode/linux_drivers/include/linux26-x86/asm/bitops.h:283: error: can't find a register in class 'BREG' while reloading 'asm'
.../genode/linux_drivers/include/linux26-x86/asm/bitops.h:283: error: 'asm' operand has impossible constraints
Any clue what I could be missing here to make these examples work? Let me know if you need more info about my environment.
Thanks.
