Hi,
I have been able to compile the rtt for lxrt fine on Debian Lenny with gcc 4.3 with RTAI patched kernel 2.6.26. I don`t have any problem running the testsuites from RTAI. However, I am getting seg faults when doing a make check. Attached are the logs for the make and make check. I did loaded the module using
insmod /usr/realtime/modules/rtai_hal.ko
insmod /usr/realtime/modules/rtai_lxrt.ko
insmod /usr/realtime/modules/rtai_sem.ko
but still fails all the tests. I have tried to start the deployer and i get a seg fault right away as well. Anyone encountered this issue before?
Thanks in advance
David

If RTAI tests work, Orocos tests should work too, we use the same API. Are you
sure only one RTAI version (also liblxrt libraries) is installed on your
system ?
If you're familiar with gdb, could you run as root:
gdb ./core-test
run
bt
where run and bt are commands for gdb. and post the result of 'bt'.

Hi Peter,I ran gdb and
Hi Peter,
I have only one liblxrt installed at the moment. I had a different version previously but I made sure it was removed with make uninstall and make clean. I also removed the /usr/realtime/ directory before installing the new version. If i do a updatedb and locate liblxrt, I have it in /usr/realtime/lib/ and the rtai source directory.
I ran gdb and here's the output i got.

This looks catastrophic. Do the unit tests work if you compile for the
gnulinux target ? Just to be sure that we aren't hunting bugs not related to
RTAI. Also, did you change any configuration or build option in cmake ?
Peter
Yes the tests passes under
Yes the tests passes under gnulinux and I was able to load deployer and cdeployer without problem. No I did not change any configuration beside setting the target to lxrt.
It appears to have
It appears to have something to do with the compiler version, I was compiling previously with gcc 4.3. I changed to gcc 4.1 and recompiled/reinstalled rtai and orocos-rtt and I was able to pass the tests. I have also compiled orocos-ocl successfully, however when I attempt to start any of the deployer:

Yes, but have you configured the dynamic linker to know where the
libaries are? This was answered on the list only a few weeks ago, but
for most Linux distro's, add /path/to/lib (within which liborocos-
xxx.so resides) into /etc/ld.so.conf (or similar) and run "sudo
ldconfig"
We need a how-to/troubleshooting/common-problems section on the
wiki .... same thing keeps popping up ... and it isn't always easy to
grok mail lists to find this sort of answer. IMHO.
