[etherlab-users] Etherlab Prerequisites

[Viktor Rees]

Hi there,

I mangaged to get RTAI 3.7 installed on Suse 11.0 (Kernel 2.6.25.5). 

When trying to install etherlab I got following error:

mylinux:/opt/etherlab/etherlab-1.2-rc5 # ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking RTAI path... /usr/realtime
checking Linux kernel path... /usr/src/linux
checking IPIPE configured in kernel... yes
checking EtherCAT path... configure: error: No installed EtherCAT found in
//opt/etherlab

As documented in the etherlab manual (Chapter: 3.1 Prerequisites) the
EtherCAT Master should be an optional dependency:

". optional: EtherCAT master 1.4, if the Simulink EtherCAT blocks shall be
used. See http://etherlab.org/en/ethercat
<http://service.gmx.net/de/cgi/derefer?TYPE=3&DEST=http%3A%2F%2Fetherlab.org
%2Fen%2Fethercat> ."

1.) Where is my problem? Is EtherCat Master an optional dependency to
Etherlab?


2.) Unfortunaetly I wasn't successful to install EtherCat Master 1.4.0:

mylinux:/home/vrees/ethercat-1.4.0 # ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes

checking whether the C++ compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C++ compiler... yes
checking whether g++ accepts -g... yes
checking for style of include used by make... GNU
checking dependency style of g++... gcc3
checking for Linux kernel sources... /usr/src/linux-2.6.25.5 (Kernel
2.6.25.5-pae)
checking for kernel for 8139too driver... configure: error: kernel 2.6.25
not available for 8139too driver!

I found out that the problem is a missing 8139too driver for my kernel in
the devices subdir:

mylinux:/home/vrees/ethercat-1.4.0/devices # ls -al 8139too*
-rw-r--r-- 1 vrees users 74894 Dec 29 15:10 8139too-2.6.13-ethercat.c

-rw-r--r-- 1 vrees users 70876 Aug 13  2008 8139too-2.6.23-orig.c
-rw-r--r-- 1 vrees users 74831 Dec 29 14:52 8139too-2.6.24-ethercat.c
-rw-r--r-- 1 vrees users 70749 Aug 13  2008 8139too-2.6.24-orig.c

I don't know which kernel I should use. RTAI only supports hal-linux patches
for kernel 2.6.24-x86, 2.6.25-x86 , 2.6.27.19-x86, 2.6.28.7-x86. This does
does not really match with 8139too-versions available for Ethercat Master. 

2.) So I cannot find kernel version that fits all involved participants. How
can I get off this situation?
