rebuilding the driver
Even if you are using a Linux distribution that already ships with the Gigaset drivers, you may still want to rebuild them yourself in order to take full advantage of their capabilities. The most frequent reason for this is that your distribution did not enable the recommended configuration options, GIGASET_CAPI to enable CAPI 2.0 support and GIGASET_DEBUG to enable debug messages.
Rebuilding the drivers requires three steps:
- install required software packages
- prepare the source tree
- actual compilation and installation
installing required packages
Building a kernel module requires certain software packages, notably
- C development tools (C compiler, linker, etc.)
- kernel source tree
- kernel symbols
preparing the source tree
In order to build modules that will be usable with the installed kernel, the kernel source tree has to be prepared with that kernel's configuration. The following commands have been tested with openSUSE 11.4 but should work for other distributions as well, possibly with small adaptations. They must be run as "root" because the /usr/src/linux directory is typically not writable by regular users:
cd /usr/src/linux make clean cp /lib/modules/$(uname -r)/build/.config . cp /lib/modules/$(uname -r)/build/Module.symvers . make menuconfig make scripts make prepareThe make menuconfig step will run the kernel configuration utility. (You may use make nconfig or make xconfig if you prefer; the latter requires the Qt development libraries to be installed.) Go to the section
Device Drivers - ISDN Support - Siemens Gigaset supportand set the configuration options:
- Gigaset CAPI support to enable CAPI 2.0 support (recommended for kernel release 220.127.116.11 and later)
- Gigaset debugging to enable debug messages (recommended except for systems with very limited resources)
compiling and installing
After preparing the source tree, the Gigaset driver modules can be compiled and installed with the commands (to be run as "root"):
cd /usr/src/linux make M=drivers/isdn/gigaset make M=drivers/isdn/gigaset modules_install depmod -aThe newly compiled modules will be installed in the 'extra' modules directory of the current kernel. The separate depmod -a command is necessary, otherwise the system will continue using the original ones in the 'drivers' directory.
Now that you have installed the Gigaset drivers with the options you need, go ahead with setting them up as described on the driver page.
