plugin question

[Matt Brown]

Hi,

I'm pretty new to Genode so this is probably going to sound like a trivial
question:

I've been playing around with many of the examples you've provided and I
saw that you guys have included qt support so I played with most of the
examples. I then tried porting over a network messaging app that I wrote a
while ago. I got it to load but when I try to establish a connection the
log says "no plugin found for socket()". I looked at the arora target and
run files to see if there was anything NIC/socket related that I should add
and I found "set feature(NIC) 1" but that didn't work.

Is there something I'm missing?

My app is trying to make a connecting using the QTcpSocket library. Any
help would be greatly appreciated.

Thanks

-Matt

You have to link your component against a libc plugin that provides the
socket API, e.g., libc_lwip_nic_dhcp or libc_lxip. If you take a closer
look at Arora's target.mk file you will see that the lwip plugin is
indeed added to the LIBS variable.

Josef,

I tried adding the library to the target.mk of my application and it didn't
work. I noticed that even though I added the library it wasn't addressed in
the build output. Just to make sure I'm doing this correctly in my target.mk
I added:

LIB += libc_lwip_nic_dhcp

*QT5 stuff*

I feel like maybe I'm missing a prepare_port call but the make script is
telling me I am.

Thanks for the help,

It could be that it tries to open an IPv6 socket, I believe I've seen this
error in that case.

Hi Matt,

welcome to the list!

LIB += libc_lwip_nic_dhcp

the variable is called 'LIBS', not 'LIB'.

Cheers
