Thanks for support. In fact I am not using dlopen directly (dynamic linking) but in ordering the linking I got it working (without having to set the flag which might be set underneath). I'm quite surprised thougth that is is a "soft" dependency. Is it my bad not having used --xeno-config directly ? (I use a shortcut because all the stuff is under CMake and I am not an expert with it). _______________________________________________ Xenomai-help mailing list Xenomai-help@gna.org https://mail.gna.org/listinfo/xenomai-help
