Hi all,
I have a little problem with the installation of rtnet and my new RT-System. I
use Xenomai 2.5.6 with a 2.6.37.6 Linux kernel.
I tried to configure rtnet with it's script:
./configure --with-linux=/usr/src/linux
--with-rtext-config=/usr/xenomai/bin/xeno-config --enable-examples
--enable-rtcap
I got this error message:
checking for RT-FireWire installation... none
configure: error: *** Unsupported kernel version
In the error message there is no information about the versionnumber. But in
the script I saw thet the number should be print out.
So I repleased the line:
RTEXT_LINUX_VERSION=`grep "#define UTS_RELEASE" $LINUX_RELEASE_FILE 2>/dev/null
| sed -e 's/[^\"]*\"\([^\"]*\)\"/\1/'`
with:
RTEXT_LINUX_VERSION=2.6.37.6
because I thought that it was not possible to read out the kernel Version and
this cause the failure. With this modification the script runs fine. But when I
tried to make "make" I got the following message:
Making all in stack
make[1]: Betrete Verzeichnis '/usr/src/rtnet-0.9.12/stack'
Making all in .

For me it seem so that the function local_inc is not longer in linux/module.h.
I tried it with
__this_cpu_inc(module->refptr->incs);
instead of:
local_inc(__module_ref_addr(module, get_cpu()));
but this causes a lot of other errors.
Does somebody has an idea?
regards,
franz
