PCAN Driver for Linux
=====================

This directory contains the files needed to download the linux driver
for PEAK CAN controllers, to compile the driver and to build RPMs. 


Preparation
-----------

Requirements for building:

  - gcc
  - g++
  - make
  - kernel headers
  - redhat-rpm-config

The following command should do the trick for SLC5:

yum install gcc gcc-c++ make redhat-rpm-config
yum install kernel-headers-`uname -r` kernel-devel-`uname -r`

If you want to compile the packages as a normal user instead of root,
you have to set up ~/.rpmmacros to contain a line like this:

%_topdir /home/trd/RPM/

This directory has to contain the directory structure to build RPMs,
i.e. SPECS/ SOURCES/ SRPMS/ RPMS/noarch RPMS/i386 BUILD/.


Building
--------

The whole build process can be started with:

    make rpm

The RPMs will be build under the RPM topdir specified above.


ToDo
----

There should be the possibility to provide modules for several kernel
versions at once.


Frequent Problems:
------------------

Problem: build fails due to unknown rpmbuild macro

    error: line 13: Dependency tokens must begin with alpha-numeric, '_' 
    or '/': BuildRequires: %kernel_module_package_buildreqs

Solution: yum install redhat-rpm-config
