$ brctl addbr br0 add bridge failed: Package not installed $ grep BRIDGE /usr/src/linux-3.2.2/.config # CONFIG_BRIDGE is not set |
really not the best error message for a missing kernel feature.

MODULE ip_tables not found |
as the last posts show I’m compiling and configuring my own kernel. As I want iptables to work, I opened my .config and enabled all flags under “IP: Netfilter Configuration” by changing the comment from “#… is not set” to “…=y”. Then I answered all questions as needed during the next compilation leaving the most question on the default value.

* Unable to find the QT4 tool qmake. Trying to use QT3 * * Unable to find any QT installation. Please make sure that * the QT4 or QT3 development package is correctly installed and * either qmake can be found or install pkg-config or set * the QTDIR environment variable to the correct location. |
for using make xconfig to configure your kernel, you need to install the following packages:
qt4-qmake
libqt4-dev

* Unable to find the GTK+ installation. Please make sure that * the GTK+ 2.0 development package is correctly installed... * You need gtk+-2.0, glib-2.0 and libglade-2.0. |
for configuring your kernel with make gconfig, you need to install the following packages:
libgtk.2.0-0
libgtk2.0-dev
libglade2-0
libglade2-dev
glib2.0-0
libglib2.0-de

*** Unable to find the ncurses libraries or the *** required header files. *** 'make menuconfig' requires the ncurses libraries. *** *** Install ncurses (ncurses-devel) and try again. |
if you want to make changes to your kernel configuration under ubuntu 11.10 you have to install libncurses5-dev to be able to run make menuconfig.
Since kernel version 3.2 my network driver doesn’t compile anymore. I downloaded the latest version from Realtek and made the following change in r8168_n.c:
|
1 |
addr = ((void *) page_address(frag->page)) + frag->page_offset; |
to
|
1 |
addr = ((void *) page_address(&frag->page)) + frag->page_offset; |
After this change the driver compiled and worked again.
To compile your own kernel you can follow these steps

I have the problem, that ubuntu uses the wrong driver for my ethernet card, so I have to use a self compiled driver. After compiling the driver I got a file r8168.ko that is automatically copied to /lib/modules/uname -r/kernel/drivers/net/. So far so good. The problem is, that the module is not found by modprobe. Therefore insert the appropriate path (kernel/drivers/net/r8168.ko) into /lib/modules/uname -r/modules.dep and /lib/modules/uname -r/modules.order. Make sure not to forget the colon in modules.dep. Then run depmod -a to make modprobe r8168 work.
