Cannot compile swconfig

[k.szczesny@…]

I'm getting this when compiling debwrt [in swconfig package:]

Seems that adding:

#define _GNU_SOURCE

on top of cli.c fixes the problem.

always something...

Any idea what's wrong?
Maybe it's because I am just running build.sh not to build the whole damn thing for another hour...?

[k.szczesny@…]

Is there any chance I could download the packages compiled for ar71* ?
I really need to have swconfig in order to get the damn switch working :/
I am going through all of the build process in order to get this one thing working :/
I don't have access to .lan .wan devices.
devices connected to the switch will not see one another :/
damn

can I somehow take the swconfig which can be built as part of openwrt and install it on debwrt?

Thanks in advance

[stappers]

There was an update on the swconfig from Openwrt.

Will have to look into this.
I have to say I am getting tired with it.

[stappers]

For me is a succesfull compile of swconfig possible,
at least it was last night.

My build system has nl stuff available as side effect of building libnl.
My guess is that libnl has to be build, before the build of swconfig starts.

[k.szczesny@…]

Phew... finally made it
I had to make this changes to the swconfig patches though:
[as suggested by stappers before:]

And I was finally able to compile on Ubuntu 10.10

Unfortunately, same set of patches on OpenSUSE using the Xeno Build technique didn't work.
I guess I am missing some libs here and there :/ Not sure which though.

Thanks!

Thanks! Committed in changeset #170.
