Problem with orocos under xenomai

Hi,

I am switching to xenomai and I have a can driver that require to link
against libpthread and librtdm. But when I load my stuff in the taskbrowser
I have :
0.103 [ ERROR ][Logger] could not load library
'/opt/ros/orocos_toolchain_ros/rtt/install/lib/orocos/xenomai/./types/librtt-transport-mqueue-xenomai.so':

Whereas ldd find correctly the link :

Does anyone know what's happening here ?

I tried to statically link and I get
/usr/bin/ld:
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../../lib/libpthread.a(unwind.o):
relocation R_X86_64_32S against `.text' can not be used when making a shared
object; recompile with -fPIC
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../../lib/libpthread.a: could
not read symbols: Bad value

So maybe things related to my 64b linux is under the woods

I believe the solution to this issue is is to build Xenomai with the "--enable-dlopen-skins" option. If you're using "configure", just make it an option of that. If you're going with the Debian package, edit the ./debian/config file and add the option to the list.

Apologies… that should be "./debian/rules".

CONFIG_OPTS += --enable-dlopen-skins

Thanks for this, I'll try.

I am currently using pre-build package that I have taken from newer Debian
releases :
root@ard-host:/usr# dpkg -l | grep ii | grep xenomai
ii libxenomai-dev 2.5.6-2
Headers and static libs for Xenomai
ii libxenomai1 2.5.6-2
Shared libraries for Xenomai
ii xenomai-runtime 2.5.6-2
Xenomai runtime utilities
I wonder why this option is disabled since there a shared library package,
but nayway.
