Hi,
     I am facing problem running Xenomai test programs and it gives me following error.
>clocktest
>/usr/xenomai/bin/clocktest: error while loading shared libraries: /usr/xenomai/lib/libpthread_rt.so.1: ELF file OS ABI invalid

similar error is seen when I try to run latency or any other Xenomai test program.


I am using Xenomai 2.5.6 patched to Kernel 2.6.37. When I do uname and dmesg following are the output

>uname -a

Linux (none) 2.6.37-ipipe #2 SMP PREEMPT Mon May 30 15:28:24 IST 2011 i686 unknown

>dmesg | grep I-pipe

[    0.000] I-pipe 2.9-0: pipeline enabled.
[    2.330] I-pipe: Domain Xenomai registered.

>dmesg | grep Xenomai
[    2.330] I-pipe: Domain Xenomai registered.
[    2.336] Xenomai: hal/i36 started.
[    2.339] Xenomai: scheduling class idle registered.
[    2.330] Xenomai: scheduling class rt registered.
[    2.302] Xenomai: real-time nucleus v2.5.6 (Wormhole Wizards) loaded.
[    2.307] Xenomai: SMI-enabled chipset found
[    2.309] Xenomai: SMI workaround enabled
[    2.305] Xenomai: starting native API services.
[    2.306] Xenomai: starting POSIX services.
[    2.302] Xenomai: starting RTDM services.

What I tried-
- Tried setting LD_LIBRARY_PATH=/usr/xenomai/lib/
- Tried rebuilding xenomai with
     --enable-x86-sep --enable-smp --host=i686-linux CFLAGS="-m32 -O2" LDFLAGS="-m32" option
    and also only --enable-x86-sep --enable-smp options

- Tried building and running 'rtprint' example program and had same error.
- Tried to statically link the 'rtprint' example program and got following error

gcc -static -I/media/New1/Linux/xenomai/install/usr/xenomai/include -D_GNU_SOURCE -Wall -pipe -D__XENO__ -L/media/New1/Linux/xenomai/install/usr/xenomai/lib -Xlinker -rpath -Xlinker /media/New1/Linux/xenomai/install/usr/xenomai/lib -o rtprint rtprint.o -lnative -lxenomai -lpthread_rt -lrtdk
/usr/bin/ld: cannot find -lc
collect2: ld returned 1 exit status
make: *** [rtprint] Error 1

Please help me to solve this problem.

Thanks & Best regards,
Sanjay

There is no need to try 100 different things. First try to compile
Xenomai and run the tests it contains. If that does not work, no need to
go further.

The problem you have seems to be a toolchain problem: the toolchain you
use does not seem to correspond to the libraries installed. Where does
the libc you use come from? Where does the toolchain you use come from?

Hi Gilles,
     Thank you very much for your quick reply. I tried replacing latest 'lib' files into my 'Initramfs' and Xenomai
clocktest worked fine. I will start my RTOS porting now.

Thanks again.

Best Regards,
Sanjay
